I design and ship production TypeScript and AI systems for fintech and SaaS.
Hi! I'm Martin. I'm a senior software engineer specializing in complex React/TypeScript frontends and full-stack AI/RAG SaaS products.
I own architecture, performance, and delivery end to end—and use AI agents daily to move faster without cutting corners on quality or maintainability.
