Workflow

Structured and Data-Driven LLM Implementation

To achieve these goals, we decided to create a catalog of employees’ and candidates’ skills based on CV information and to integrate it into the company’s ERP system.
Phase 1

Skills catalog foundation

Created a catalog of employees’ and candidates’ skills based on CV information.
Phase 2

ERP integration

Integrated the skills catalog into the company’s ERP system.
Phase 3

LLM implementation

Leveraged multimodal language models (LLMs) for automatic text extraction from resumes using Google Gemini Pro on Vertex AI.
Phase 4

Reporting

Built reports using Looker Studio to address knowledge management needs.
By combining multimodal LLMs with a cloud-native platform, we unlocked hidden value in CV data—accelerating hiring, improving talent visibility, and supporting smarter workforce decisions.
Solution

Multimodal LLMs and GCP Implementation

The Zoolatech team engineered a serverless, cloud-native solution utilizing advanced LLMs to transform unstructured CV data into a centralized, searchable skills catalog for an ERP system.

Multimodal LLMs

We leveraged multimodal language models (LLMs) for automatic text extraction from resumes using Google Gemini Pro on Vertex AI. LLMs can “understand” the entire document, structuring not only specified knowledge and skills but also other relevant information.
approve

GCP implementation

The solution was deployed on Google Cloud Platform (GCP) using a serverless approach with Node.js and Google Cloud Functions. This simplified deployment and maintenance.
approve

ERP integration

Integration with the ERP system was implemented in two ways:
  • REST protocol: For real-time parsing (e.g., when a recruiter uploads a new resume or converts a resume into a corporate template).
  • BigQuery: For offline parsing when indexing an existing CV database.
Results

Increased Efficiency, Time Savings, and Enhanced Talent Management

By implementing this solution, we successfully increased the efficiency of our recruitment processes, saving time and costs while enhancing its ability to find and manage talent.
The new big data platform improved operational visibility, strengthened analytics capabilities, and enabled ML-driven optimization across the retailer’s value chain.
