What I do

Four things, one throughline: helping developers ship.

I move across the stack - building products, AI tooling, and Web3 infrastructure, then teaching what I learn.

Engineering

Full-stack apps, APIs, SDKs, CLIs, and automation workflows.

AI Tooling

RAG apps, LangChain demos, MCP tools, LLM APIs, and developer-facing AI products.

Developer Education

Blogs, tutorials, workshops, videos, and code samples.

Web3 Infrastructure

Smart contracts, DApps, protocol education, and security.

Tech stack

Tools I reach for.

The languages, frameworks, and platforms I build and teach with.
