I'm a senior software engineer based in Berlin, focused on building practical, product-facing systems with React, TypeScript, Node.js and AI-assisted workflows.
I spent the last decade working across frontend, backend, internal tools, billing flows and product-heavy SaaS systems. Recently, I've been building projects around AI evaluation, retrieval quality, review queues and developer-facing AI tools.
- Building product-facing systems with React, TypeScript, Next.js, Node.js and APIs
- Designing product workflows for SaaS, billing, internal tools and support teams
- Exploring AI-assisted interfaces with structured outputs, retrieval evaluation and human review
Tests whether a help-center assistant retrieves the correct source documents before generating an answer. Compares keyword, embedding and hybrid retrieval strategies using metrics.
Analyzes UI screenshots and DOM context to produce structured frontend QA findings for accessibility, UX and implementation issues.
A review queue for support messages that identifies revenue-risk signals and turns AI output into human-reviewable product decisions.
