πŸ’« About Me

I am a Senior Software Engineer based in Zurich, focused on building production ready full stack AI products, backend systems, and data driven applications.

My strength is turning complex ideas into practical software: from backend architecture and APIs to user facing interfaces, AI workflows, dashboards, and product features that people can actually use. I enjoy working across the full product lifecycle, from idea and prototype to reliable production systems.

  • πŸ€– I design and build AI powered applications, agentic workflows, RAG systems, and LLM enabled product features

  • 🧱 I enjoy working on full stack products, backend platforms, developer friendly APIs, automation systems, and data heavy applications

  • 🧠 I am especially interested in AI product engineering, LLMOps, agentic systems, RAG, inference optimization, and human centered AI tools

  • πŸ› οΈ Main stack: Python, TypeScript, NextJS, React, Node.js, FastAPI, NestJS, PostgreSQL, Docker, and cloud infrastructure

  • πŸ“Š I like building products around financial data, on chain data, analytics dashboards, AI assistants, and decision support systems

  • πŸ”— I also bring experience and interest in Web3 infrastructure, DeFi protocols, trading systems, and data platforms

  • πŸ’¬ Ask me about full stack AI products, AI backend architecture, RAG, agentic workflows, product engineering, or backend systems at scale

  • ⚑ Fun fact: I enjoy turning messy data and abstract AI ideas into clean, useful products, preferably with a strong backend, a simple UI, and a clear user problem behind it


πŸš€ Featured Focus

🧠 AI Research and RAG Systems

I am currently exploring and building systems around:

  • Multi agent orchestration with graph based workflows
  • RAG pipelines with semantic search, chunking, reranking, and evaluation
  • LLM observability, tracing, and regression testing
  • Prompt versioning, evaluation gates, and model comparison
  • Backend APIs that connect AI workflows with real product use cases

Typical stack:

Python Β· FastAPI Β· LangGraph Β· LangChain Β· LangSmith Β· Langfuse Β· Supabase Β· Pinecone Β· PostgreSQL Β· React Β· TypeScript Β· Docker
