  • CIBUS - online store for ordering products

    AI & Machine Learning
    I am developing from scratch the CIBUS startup - an online store for ordering products and managing sales. The project includes a client part, an admin panel, backend logic, working with products, categories, the cart, orders, authorization, and the business logic of the platform.

    Within the project, I work as a fullstack developer: implementing the frontend, API, database integration, form validation, order processing, admin functionality, bug fixing, and technical optimization of the product. I also focus on improving the code structure, updating dependencies, configuring the Docker environment, and preparing the project for stable operation.

    … Technologies: Next.js, React, TypeScript, Node.js, PostgreSQL, Docker, pnpm, Git, REST API.

  • RAG system for semantic search in web documents

    AI & Machine Learning
    Development of a RAG system for semantic search, analysis, and processing of a large number of web documents using LLM.

    Within the project, backend logic was implemented for document indexing, working with embeddings, chunk-level search, vector search, and generating structured responses based on relevant sources. The system allows finding the necessary information in the document database and returning answers with contextual relevance.

    … Worked with API endpoints, synchronization of embeddings, document processing, retry logic, queue-based update tracking, and API key authentication. Used Flask, PostgreSQL, pgvector, Docker, OpenAI / Azure OpenAI embeddings, and pytest.
