About

Build fast. Ship with AI.

I'm a software and AI/ML engineer who owns products end to end, from the data model and backend to the last pixel. Lately that means LLM applications, retrieval-augmented generation (RAG), and production-grade backends.

I build websites, desktop apps, and mobile apps powered by AI, and I set up AI workflows and automations that quietly remove busywork, usually in days. I optimize for fast delivery, reliability, and code the next developer can actually read.
