Matt Wilson
Senior Full Stack & AI Engineer
4 years shipping production software — investment platforms, fintech mobile apps, and AI tooling.
About
Self-taught. Got into programming after discovering Bitcoin in 2022 — fell down the rabbit hole, started building, and never stopped. 4 years later I'm shipping production software across investment platforms, fintech mobile apps, and AI tooling.
I specialise in TypeScript across the full stack — Next.js, NestJS, React Native — and I've worked end-to-end on everything from frontend architecture to backend APIs to CI/CD pipelines. Currently building Ralph, an autonomous AI developer agent.
Based on the Isle of Man, working remotely. I care most about writing software that works well and solving problems cleanly — the rest follows from that.
Beyond the code — Runs ultra marathons and rides bikes when not at a keyboard.

Projects
Ralph
Autonomous AI developer agent that reads your codebase and executes full development pipelines.
Problem
Building software is slow and repetitive — even with AI copilots, developers still manually orchestrate the build-test-fix-ship cycle.
Results
Autonomously builds, verifies, and ships features — including creating PRs. Used to build this very website.
LeaseLink
Full-stack property management platform — web dashboard for managers, mobile app for tenants. Built entirely with Ralph.
Problem
Property managers juggle spreadsheets, emails, and disconnected tools. Tenants have no transparent access to leases, payments, or maintenance status.
Results
Full platform with lease lifecycle management, automated rent collection, maintenance workflows, and multi-factor tenant onboarding. Built end-to-end by Ralph autonomously.
Imperium
AI knowledge management platform for businesses, with cost-optimised LLM routing and automated data ingestion.
Problem
Business knowledge scattered across Gmail, Drive, Calendar, and messaging apps with no unified structure or searchability.
Results
Deployed on Hetzner, used daily. 600+ tests at 93% coverage. Production-grade with CI/CD, Caddy reverse proxy, cron backups.
Athena
Personal AI built on a living knowledge graph that reasons across your goals, relationships, finances, and decisions.
Problem
Generic AI assistants have no real context about you. They can't catch contradictions, track commitments, or give advice informed by your actual life.
Results
In active daily use. Solo-built end-to-end, currently mid-Epoch 6 with Ralph handling remaining sprint work.
