I build scalable, intelligent software across the stack, from Rust systems and AI-integrated APIs to full-stack web apps and native iOS. I care about clean architecture, real performance numbers, and shipping things people actually use.

Halley — Your production traffic is your test suite.

An open-source, self-hostable LLM observability and regression testing platform. It records production AI agent runs as bit-fidelity cassettes, turns any run into a permanent regression test, and replays your whole fixture library in CI at $0 LLM cost, then bisects to the exact commit that broke it.

• ⚙️ Rust ingester (tokio, axum, tonic), OpenTelemetry-native, normalizes 5 trace dialects into one canonical schema
• 📊 Next.js 14 dashboard · TypeScript & Python SDKs · halley ci CLI for replay and bisect
