Industry Leaders We Work With

What Data Engineering Covers

Data Engineering, Defined

Data engineering moves data from systems that produce it to systems that depend on it.
Ingestion

Ingestion

Batch loads, change data capture, and API pulls extract records without slowing the source applications that own them.
Streaming

Streaming

Event streams carry clicks, orders, and payments as they happen, so consumers react in seconds, not after a nightly batch.
Transformation

Transformation

Versioned logic turns raw records into consistent, joined, deduplicated tables and produces the same output every time it runs.
Data modeling

Data modeling

Shared definitions of customer, order, and product sit underneath every metric, so two teams querying revenue get one answer.
Storage

Storage

A warehouse, lake, or lakehouse holds history at a price and query speed matched to how the business reads it.
Orchestration

Orchestration

Schedulers and dependency graphs run each step in order, retry failures, and backfill history without anyone rerunning jobs by hand.
Testing

Testing

Automated checks on every run say whether today’s output can be trusted before a report or model consumes it.
Analytics boundary

Analytics boundary

Engineering builds the layer, and analytics computes on it. Dashboards built before pipelines are reliable produce numbers people argue about.

“By 2028, 80% of GenAI business apps will be developed on existing data management platforms.” — Gartner

The platform your team runs today becomes the base for tomorrow’s AI applications. Zoolatech engineers that base as tested code, ready for new workloads.
Services We Deliver

Data Engineering Services We Deliver

Scope your backlog against data engineering services and solutions with named tools and measured results.

Pipeline design and build

Batch and event pipelines run on Apache Kafka, Apache Spark, and Apache Airflow, the stack behind a Fortune 500 retailer’s platform. Our big data engineering services plan for idempotent reruns and schema drift from the first commit.
check icon

Streaming and real-time ingestion

Event collection replaces delayed batch exports when decisions depend on the last few minutes. For Zalando, mobile analytics events that once arrived 15–90 minutes late now land in near real time through an abstraction layer over Google Analytics 4.
check icon

Data integration

Data integration engineering services connect operational databases, SaaS tools, and event streams behind one access layer. A low-code data platform we built on GraphQL and PostgreSQL consolidated access to several source systems through a single interface.
check icon

Transformation and modeling

Versioned transformation logic turns raw events into modeled tables with lineage back to every source. Spark jobs in Zalando’s customer data pipeline feed Braze campaigns and Looker reporting from the same tables, the base that data analytics engineering services need.
check icon

Warehouse and lakehouse build

Storage layers go live on Azure Databricks, Azure Synapse, Google BigQuery, and Teradata. We size clusters, partitions, and retention to your query patterns instead of vendor defaults, which keeps query latency and the monthly bill predictable.
check icon

Platform migration and modernization

Data engineering and modernization services move pipelines off aging schedulers and on-premises warehouses through staged migration and output reconciliation. For a global retailer, a unified platform built on Azure Databricks replaced fragmented data processing and enabled near real-time insights.
check icon

Data quality engineering

Schema checks, tests, and reconciliation jobs run in continuous integration (CI) on every change and again on every scheduled run. Bad records stop at the stage that produced them, while threshold design stays with the data owners.
check icon

Managed pipelines and support

After launch, pipeline operation can include monitoring, dependency upgrades, and cost reviews, with scope agreed with you at the start. On a job-processing platform, job-level telemetry we built in Datadog made every job traceable and brought vanishing jobs down to 0.
Consulting and Advisory

Data Engineering Consulting Services

Enterprise data engineering consulting gives leadership an evidence-based plan before a budget commits to a platform, migration, or team.
01

Platform assessment

We inventory sources, pipelines, and failure history, then rank what blocks delivery now. You receive written findings with evidence attached.
02

Target architecture

Data engineering advisory services compare warehouse, lake, and streaming options against your latency, cost, and skills constraints, with trade-offs stated.
03

Roadmap and sequencing

A sequenced plan names the first pipeline to ship, the sources that follow, and the decisions your team must make.
04

DataOps maturity review

We examine how pipeline changes get versioned, tested, and released today, then list the gaps behind your production incidents.
Your pipelines run as code, pass tests before production, and flag a broken run before anyone decides on it. One team delivers data engineering services and data engineering consulting services.

DataOps in Practice

How We Run Data Platforms: DataOps

Your platform keeps changing long after launch. DataOps puts every change through version control, automated tests, and identical environments before it touches production data.
Step 1

Terraform and AWS CloudFormation describe every cluster, queue, and permission in version control. Your team rebuilds an environment from the repository and reviews infrastructure changes like application code.
Step 2

Each pipeline change opens a merge request in GitLab CI/CD, where builds, unit tests, and data tests run automatically. A change that fails never reaches production, and every release leaves an audit trail.
Step 3

Development, staging, and production share the same definitions, versions, and configuration. A transformation that produces one number in staging produces the same number in production, so release day holds no surprises.
Step 4

Unit tests cover transformation logic, and data tests assert row counts, uniqueness, and referential integrity on sample and full datasets. Failures block the merge, so defects surface in review instead of in a dashboard.
Data Platform Architecture

Platforms We Build On

Modern data architecture engineering services start with the storage pattern that fits how you query.
Data warehouse
Data lake
Lakehouse
Streaming-first

Governed SQL analytics

Choose a warehouse when reporting and finance need consistent, governed answers from structured data.
  • Inside: Modeled schemas, a semantic layer shared with analytics teams, and scheduled loads that preserve full history.
  • You pay for: Compute per query and storage per terabyte, a pricing model that rewards well-modeled tables.
  • Our example: Cloud data warehouse engineering services on Google BigQuery, running alongside Teradata for a Fortune 500 retailer.
Image slot

Raw, cheap storage

Choose a lake when you must keep raw, varied data before every use is known.
  • Inside: Cloud data lakes engineering services organize object storage into raw, cleaned, and curated zones with a catalog on top.
  • You pay for: Low-cost storage, with compute billed only while jobs run, so dormant data stays cheap.
  • Our example: Enterprise data lake engineering services that land retail data through Kafka and Azure Data Factory for downstream processing.
Image slot

One governed copy

Choose a lakehouse when analytics and machine learning must read the same governed tables.
  • Inside: Transactional tables on object storage, with notebooks and SQL endpoints reading one copy of the data.
  • You pay for: Cluster hours, which makes auto-termination and right-sizing your main cost levers.
  • Our example: A global retailer’s platform on Azure Databricks and Synapse cut time to insight and ownership cost.
Image slot

Events come first

Choose streaming-first when the business acts on events within seconds, not on reports.
  • Inside: Kafka topics as the system of record, stream processors, and sinks into a warehouse or lake for history.
  • You pay for: Always-on brokers and consumers, so partition counts and retention settings drive the bill.
  • Our example: Data platform engineering services on Kafka and Airflow that give a Fortune 500 retailer one real-time data feed.

Choosing a cloud

Event-driven on AWS

AWS data engineering services from Zoolatech center on event-driven designs that scale down as well as up.
  • Delivered work: Kafka on Kubernetes with Terraform and Splunk for a fashion retailer, plus Lambda, SQS, and CloudFormation for payments.
  • AWS services for data engineering: Queues, functions, and containers matched per workload keep data engineering services in AWS cost-proportional.

Lakehouse on Azure

Azure data engineering services cover ingestion through reporting inside one tenant and one security model.
  • Delivered work: Azure Data Factory, Databricks, Synapse, and Power BI assembled into a unified data platform for a global retailer.
  • Where it fits: Data engineering services in Azure suit enterprises standardized on Microsoft identity, networking, and procurement.

Analytics on BigQuery

Data engineering services in GCP (Google Cloud Platform) center on BigQuery as a serverless warehouse for very large datasets.
  • Delivered work: Google BigQuery fed by Kafka and Airflow pipelines inside a Fortune 500 retailer’s big data platform.
  • Where it fits: Teams that want warehouse scale without managing clusters and that accept per-query pricing discipline.

Familiar cloud first

The right cloud for a data platform is usually the one your team already operates.
  • When migration is justified: Latency or cost profiles make the current cloud untenable, not because another vendor’s stack looks newer.
  • What we check first: Existing skills, identity and network setup, committed spend, and where your source systems already live.

AI and ML Data

Data Engineering for AI and ML

Models inherit every flaw in the data layer beneath them, so that layer comes first.

Training data layer

Data science engineering services deliver versioned, documented datasets, so your data scientists stop rebuilding extracts for every experiment.

Feature delivery

Feature pipelines compute the same values for training and serving, and point-in-time snapshots make any model result reproducible.

Unstructured data preparation

Text, images, and documents get parsed, deduplicated, and staged with metadata, ready for labeling, annotation, or retrieval pipelines.

Readiness handoff

AI data engineering services build the layer. A separate readiness assessment scores whether that layer meets a specific model’s needs.

“Data-related issues cause 55% of organizations to avoid certain generative AI use cases.” — Deloitte

Use cases stall when the data beneath them cannot be reproduced. Zoolatech gives your AI program versioned, tested pipelines before the first training run.
Run-Time Controls

Enforcing the Thresholds

Monitoring enforces the thresholds the data owners set, on every run, before consumers see output.

Pipeline-gating tests

Every scheduled run passes freshness, volume, and schema checks before it publishes. A failed run never reaches downstream tables.

Monitoring against thresholds

Datadog and Splunk track each stage against its limits. On one job-processing platform, incident triage dropped from hours to minutes.

Hold and replay

A failed run is held, not published. Engineers fix the cause, replay retained inputs, and release corrected output.
Engagement Models

How We Work With You

Whether you outsource data engineering services entirely or add engineers to your own team, the right model depends on who owns the backlog and when the work ends.

Successful Projects

Consulting engagement

Choose it for an assessment and roadmap. It ends when leadership approves the target architecture.

Project delivery

Under managed delivery, we own scope through launch, then hand over code and runbooks.

Dedicated data team

Through team extension, our engineers join your squads, and your backlog directs them.

Managed pipelines

We operate pipelines after launch through on-call response, upgrades, and cost reviews.

Backlog ownership

You own it with consulting and dedicated teams. We own it in delivery and operations.

Team composition

Team size and roles follow your source count, latency targets, and scope, agreed during discovery.

Outsourcing at scale

Outsourcing data engineering services long term can grow into a dedicated offshore development center.

Switching models

Engagements often start as consulting, continue as delivery, and settle into managed operation.

Platform Economics

What the Platform Costs to Run

See where platform spend leaks, what re-architecture returns, and what sets your project’s price.
Idle clusters

Idle clusters

Clusters that wait between jobs bill by the hour. Auto-termination and job-scoped compute stop billing for idle time.
Oversized nodes

Oversized nodes

Nodes sized for a peak that arrives monthly burn budget daily. We right-size from observed utilization, not vendor defaults.
Repeated reprocessing

Repeated reprocessing

Full reloads of unchanged history multiply compute. Incremental loads and partition pruning process only what changed.
Throughput gained

Throughput gained

A fashion retailer’s re-architected event pipeline on AWS and Kafka handles about 150,000 events per hour against about 21,000 before.
Compute reduced

Compute reduced

On that same platform, 3 pods of the new version do the work of 12 old ones.
Cost by design

Cost by design

We treat the cost profile as a design constraint reviewed every sprint, not a bill examined later.
Sources and latency

Sources and latency

Project price scales with the number of source systems and how fresh data must be, more than with volume.
History and regulation

History and regulation

Years of backfill and a regulatory perimeter such as payment or health data add validation, masking, and audit work.
Handover or operation

Lower run cost

We re-architect to shrink the bill, not only add capacity. One retail event platform costs roughly 4x less to run.
Published case evidence

Published case evidence

Our data case studies describe the technologies, engineering work, and outcomes, including measured results where available.
Senior engineering teams

Senior engineering teams

More than 60% of Zoolatech engineers hold senior roles, a ratio we maintain through mentorship and technical leadership programs.
Engagement Process

How an Engagement Runs

You see a working pipeline early, then watch the same pattern repeat source by source. Each step ends with an artifact you keep, whether or not we continue.
Step 1

Discovery and source inventory

We interview data owners, list every source system, and record access paths, volumes, and known defects. Artifact: a source inventory with a ranked problem list. Access approvals are frequently the longest single task.
Step 2

Target architecture

We choose the storage pattern, cloud services, and orchestration against your latency and cost constraints, and document the trade-offs. Artifact: an architecture decision record and a delivery plan your architects approve.
Step 3

First pipeline in production

One high-value source goes live end to end, built as code with environments reproducible from the repository. Artifact: a production pipeline and the repository template that every later source reuses.
Step 4

Tests and monitoring

We add gating tests, dashboards, and alerts to the first pipeline, then rehearse a failed run and its replay. Artifact: a runbook and alert rules an on-call engineer can follow at night.
Step 5

Migration of remaining sources

Remaining sources move in ranked batches through the same template, with old and new outputs reconciled before each cutover. Artifact: a reconciliation report per batch and a list of retired legacy jobs.
Step 6

Run or hand over

Your team takes over with documentation, pairing sessions, and a support window, or our engineers continue operating the platform. Artifact: a handover pack or an operations agreement with defined responsibilities.
Share your source systems, priorities, and target timeline with our sales team.

Questions You May Have

What do data engineering services include?

Data engineering moves data from the systems that produce it to the systems that use it, in a shape those systems can rely on: ingestion, transformation, storage, orchestration, and the tests that say whether today’s run can be trusted. Platform migration and ongoing pipeline operation are the 2 other common scopes.

What is the difference between data engineering and data analytics?

Data engineers own the pipelines, the storage, and the models underneath the metrics, while analysts own what the numbers mean and how they are presented. Teams that start with dashboards before pipelines are trustworthy get numbers people argue about instead of act on.

How do you know a pipeline run is correct before someone builds on it?

Tests gate the pipeline instead of reports describing it afterward: transformations are tested in CI, environments stay at parity, and monitoring watches the thresholds the data owners set. A run that fails is held instead of published, and threshold design and ownership belong to data quality management services.

Do you work with AWS, Azure, and Google Cloud?

Yes, all 3: delivered work includes AWS with Kafka, Kubernetes, Lambda, and CloudFormation, Azure on Databricks, Data Factory, and Synapse, and Google Cloud through BigQuery on an enterprise big data platform. The right choice is usually the cloud your team already operates, unless latency or cost profiles make it untenable.

Can you work with our existing platform, or do you rebuild?

In most cases we work with it, because a rebuild is justified only when the platform cannot meet the latency or cost profile you need. More often the problems are structural: no tests on transformations, no environment parity, and no owner for a dataset everyone depends on.

How do you keep pipeline costs from growing with volume?

We review idle compute, node sizing, and repeated processing, then match capacity and loading patterns to the workload. Incremental loads, partition pruning, and job-scoped compute can reduce unnecessary processing as data volumes grow.

What is DataOps, and do we need it?

DataOps applies to pipelines what software teams take for granted: infrastructure defined as code, changes tested in CI before they reach production, parity between environments, and a defined rollback when a run is wrong. You need it once more than one person changes pipelines, which happens earlier than most teams expect.

How long before the first pipeline is in production?

The sequence matters more than the total: a first pipeline in production early, with tests and monitoring on it, sets the pattern every later source follows. Timelines scale with the number of source systems and the state of their documentation, not with data volume.

How do we choose a data engineering consulting partner?

Compare the best data engineering consulting companies on evidence: which clouds and tools they have run in production, whether they operate what they build, and whether their case studies state throughput, cost, and latency. A data engineering consulting company that answers in those terms measures its work, and one that promises quality in general does not.

Do you provide a team, or do you deliver a project?

Both, and the choice depends on who owns the backlog: consulting produces an assessment and target architecture, project delivery builds a defined scope and hands it over, and a dedicated team works inside your backlog. Managed pipelines keep our engineers operating the platform after launch, and engagements often move from one model to another.
