I help European startups, SMEs and product teams turn AI ideas into production-ready full-stack applications, from prototype to cloud deployed traceable product

I specialize in building AI-powered web apps such as RAG agents, GraphRAG agents, multi-agent architectures, chatbots over internal documents and data, and in general SaaS MVPs. My work usually covers the full delivery cycle: identifying and understanding the business core problem, designing scalable architecture, building the backend, integrating LLMs/(LLM agents if needed) and data sources, creating the UI, adding observability, and deploying the solution to the cloud

I bring 5+ years of experience across AI engineering, data engineering and full-stack software development and have shipped more then 5 AI systems to the production, including multi-agent architectures for civil aviation, customer-facing GraphRAG product discovery agents, agents for PDF and Excel analysis

My core stack includes Python, TypeScript, Node.js, FastAPI, LangChain, LangGraph, PyTorch, Hugging Face, Qdrant, Neo4j, Redis, SQL databases, Docker, AWS, Azure and Databricks

What makes me different is that I bridge AI research, backend engineering, data systems and product thinking. I do not just build POCs but reliable AI applications that users can actually interact with, teams can maintain, and businesses can measure

Typical deliverables I can help with:

- AI SaaS MVPs and full-stack prototypes

- RAG and GraphRAG applications

- LLM agents and multi-agent systems

- Workflow automation with AI

- AI observability, evals, tracing and performance optimization

Would be very happy to work together on something cool and AI related! :)
