About Me

Full‑Stack Developer & Support Specialist — Bridging Engineering & Customer Experience

I build reliable, user‑centered web apps and act as the bridge between technical teams and customer‑facing realities. My stack includes Ruby on Rails, React/TypeScript, Python (Flask), and growing experience with Node.js/Express. Years in SaaS support honed my API debugging, data analysis, and production troubleshooting—so I ship features that work for real users.

Recent work: Fern Finance (turns raw transactions into clear insights) and Bitcoin Journey (interactive learning app). I care about clear UX, measurable impact, and maintainable systems. If that resonates, let’s connect.
