What I'm looking for

I'm looking to build and support production systems where I can turn unclear business needs into practical architecture, reliable software, and trustworthy AI integrations while working closely with owners and non-technical teams.

At MDS Pro Solutions, I'm the sole engineer behind the timekeeping and billing platform used daily by a US healthcare staffing company. I replaced an editable payroll spreadsheet with a secure, attributed approval workflow and onboarded nurses and the owner as the system evolved.

I've spent 5+ years shipping web, mobile, automation, and AI-integrated systems end to end. My work includes source-verified LLM pipelines, a live AI website redesigner, open-source fixes for Mastra and Recharts, and WordWarz.io, a real-time multiplayer game shipped to the browser and App Store.
