React, Next.js, TypeScript, Node.js are home base. Strong on frontend architecture and security (OWASP certified), increasingly building LLM-powered products. Specialist roots, generalist range

Going deeper on LLM app engineering: evals, agentic workflows, and token observability across providers. Also getting hands-on with Aurora Postgres for a cost-attribution tool I'm building.

A token observability tool that tracks AI usage and cost across OpenAI, Anthropic, and Gemini. Building it for the h0 hackathon.

Open to remote roles with international teams (frontend + AI product, EU-authorized). Also down to chat about LLM apps, evals, or whatever you're hacking on. Reach out!
