Uses

The stack and tools I actually work with — not an affiliate-link graveyard.

Languages & frameworks#

• TypeScript / Node.js — default for product code, including this site (Next.js 15, App Router).
• Python — everything retrieval and evals: pipelines, benchmarks, notebooks.
• React — Server Components first; client components only where interaction demands it.

AI tooling#

• Claude / OpenAI APIs — model calls behind a thin gateway with logging, evals, and cost tracking.
• pgvector + hybrid retrieval — dense + lexical retrieval; rerankers where the eval set proves they pay for themselves.
• Custom eval harnesses — every pipeline change runs against a fixed eval set before it ships.

Infrastructure#

• GCP & AWS — GCP for current work; years of AWS before that.
• Vercel — this site: static-first ISR, deploys on push.
• MongoDB Atlas — backs the hand-rolled CMS behind this blog.

Editor & desk#

• VS Code + Claude Code — agentic coding for the mechanical parts; review stays human.
• MacBook Pro — one machine, no external monitor evangelism.
