Design engineer and full-stack AI engineer with 5+ years of experience designing and building production LLM products in TypeScript and Python — from interaction design and front-end implementation to backend systems and deployment.

I work across AI agents, RAG, document intelligence, voice AI and sensitive workflows, with a focus on interfaces that make complex systems clear and reliable to use.

Recent work:
• p.AI (AI pharma, Germany) — redesigned three applications end to end and built secure document pipelines that cut time spent finding information by ~40%. Added evaluation and observability to make AI features more reliable, in EU-compliant setups for pharmaceutical clients.
• Nexilan (AI language products, Switzerland) — built LLM inference systems serving 10k+ daily requests and reduced latency by 40% with semantic caching and retrieval improvements.
• AxeGenAI (USA) — shipped AI-integrated Next.js interfaces and REST APIs for a generative AI SaaS that turns requirements into AWS architecture diagrams.

What I can help with:
• AI products: LLM apps, agents, RAG with citations, voice AI (ElevenLabs, LiveKit)
• Front end and design engineering: React, Next.js, Tailwind, Figma, design systems
• Backend and infrastructure: FastAPI, NestJS, ElysiaJS, Node.js, PostgreSQL, Redis, Qdrant, Docker, AWS, Cloudflare
