Hi, I am
Founding Lead
Engineer
I lead engineering at Fintant, working remotely with a US-based team. Before that I spent two and a half years at Marthala Solutions in Germany, running project setup, monitoring, and deployment for Ausbildung Assist.
My core is full-stack product engineering — the MERN stack, with deeper specialization in NestJS and Next.js. I care most about scalable architecture, performance optimization, and clean, reviewable code that keeps a team moving quickly.
Alongside that I build with Generative AI and Large Language Models: autonomous agents and RAG systems, workflow orchestration with LangGraph, vector and graph-backed memory, and the guardrails that make AI features safe to ship.
