I like building at the frontier before it's obvious — from interactive installations and a category-defining app to today's AI agents. Alongside client work I run an independent research thread on AI interpretability & efficient neural architectures: extracting exact, verifiable logic from trained networks — the "reading the unreadable" problem.
Curious about → interpretability · the geometry of meaning & computation · generative / creative tech · psychology · markets.
TypeScript · Node · React / Vue · Python · LLM agents (Vercel AI SDK · OpenAI · Anthropic · Gemini) · Temporal · PostgreSQL / pgvector · Docker
