I design and build production ready AI systems that solve real business problems. My work focuses on large language model applications, retrieval augmented generation systems, document intelligence, and AI driven automation. I currently work as a Python LLM developer where I build AI platforms used by international teams. My experience includes building systems that analyze large documents, automate workflows, and enable natural language interaction with complex data.

My typical work involves designing reliable backends using Python, FastAPI, and modern AI frameworks such as LangChain and LangGraph. I also build scalable retrieval pipelines using vector databases like Qdrant, ChromaDB, and Milvus.

Services I provide:
AI chatbots and intelligent assistants
Retrieval augmented generation systems for private knowledge bases
Document AI systems for PDFs, reports, and contracts
AI agents that automate workflows and decision making
Natural language to SQL systems for business analytics
Voice based AI assistants with real time interaction
Custom AI APIs and backend services

I have built systems such as:
A government tender analysis platform that extracts financial and legal insights from large procurement documents.
A financial analytics platform that converts bank statements into structured insights and visualizations.
An AI recruitment system that evaluates and ranks candidates across multiple criteria.
Voice AI assistants that manage calls, reminders, and conversations in real time.

Technologies I work with include:
Python
FastAPI
LangChain and LangGraph
OpenAI and Gemini models
Vector databases such as Qdrant, ChromaDB, and Milvus
PostgreSQL and distributed data systems
Docker based deployments and cloud infrastructure

My focus is always on building systems that are reliable, scalable, and easy to integrate into existing products. I pay close attention to architecture, performance, and maintainability so the solution continues to work as your data and usage grow.

If you are building an AI product or looking to add intelligent capabilities to your existing platform, I would be glad to help design and implement the system.
