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.

What I Do

AI Product Development

You have a prototype that's hit its ceiling. I scope, architect, and build what comes next — full-stack, end-to-end, no handoffs.

AI Integration

Your team is using LLMs but it's duct tape. I build the structure: versioned prompts, agent contracts, methodology your team can run without me.

I also build custom AI tools for musicians and creators — audio analysis, generative pipelines, creative workflow tooling. More on the services page.

In Parallel

StemSense

Personal project. A co-writing assistant that works with raw audio — upload a track, talk about it, get musical ideas grounded in what you actually played. Not MIDI rolls, not generated slop. Proof of interest in the audio tools space.
