Tessellate Studio
Jon Harvey
Your no-code prototype is hitting its ceiling, or your LLM workflows live in Slack threads and nobody knows what's in production. I build the real thing — sole engineer, full ownership, architecture through deployment.
About
I'm a full-stack engineer working remotely with US-based founders and teams. I've replaced a no-code healthcare research platform serving 10,000+ patients across 55 countries, transformed a no-code consultancy into a code-first operation with a complete engineering methodology, and shipped AI content systems for consumer SaaS — each time as the sole engineer. If you need someone who can hold the technical vision and build it, not just execute a spec, that's the work I do.
In Practice
“Jon was able to deep dive into our messy codebase and still make sense of it in little time. His capacity to turn chaos into order was very helpful. Jon can spot patterns and digest large amounts of logic and information — and he's efficient in using the latest AI models to make the most of his time.”
— Uri Riera, Founder, LongStories
“Jon is a systems thinker who ships clean. He helped systematize things so thoroughly that the handoff step he was filling eventually became automatable — he helped shape the very system that made his role unnecessary. I'd highly recommend anyone looking for an engineering leader on a small team, or an engineering partner to bring clarity to a vibe-coded mess.”
— Wes Wagner, Principal & Founder, Rarely Decaf
What I Do
I also build custom AI tools for musicians and creators — audio analysis, generative pipelines, creative workflow tooling. More on the services page.
