No hype. Working systems.
I don't sell potential. Every project ends with something you can run on Monday. If a model isn't the right tool, I'll say so.

Things I've shipped.
Rizzma
2024 — 2026A dating-assistant app that writes what to say next, powered by a private multi-model pipeline.
Built solo end-to-end: React Native app, Python backend, RAG over conversational context, fine-tuned response generation, subscription billing, App Store launch.
Visit rizzma.io§ 03ApproachPrinciples, not process theatre.
How the work gets done.
Solo through the full stack.
Design, frontend, backend, infra, hardware if needed. One person keeping the mental model means less friction, faster iteration, fewer bugs.
Your data stays yours.
Comfortable with local LLMs, private inference, GPU servers. If privacy matters, nothing has to leave your box.
Built to be maintained.
Documented. Tested. Handed off cleanly. I've been the only engineer on teams — I know what good handoff looks like.

What people say.
Give Liam any project and he can deliver it on time and efficiently. He is a natural born leader when it comes to managing and building any project.
Work was excellent, efficient, and very easy to work with. The quality speaks for itself. Will work with him again on future projects.
Met in Tokyo, bonded over cocktails. Big vision, serious ability to deliver. He helped us build systems we couldn't have done alone.
