Zona Gilreath

Senior full-stack engineer specializing in React, TypeScript, and Node.js. Five years leading patient payment products at athenahealth — $2.5B in annual volume, 30M users. Now available for freelance and contract work.

What I can build for you

I work best on focused, high-impact engagements — typically 1–6 months. Here's what I bring to the table.
End-to-end feature builds from database to UI. React frontends, Node/TypeScript backends, and everything in between.
From zero to deployed. Tech stack selection, infrastructure setup, CI/CD, and a codebase structured to hand off cleanly when the engagement ends.

How I work

I build production web applications with an emphasis on clarity — predictable data flow, type-safe boundaries, and interfaces that feel fast and obvious. I care about the whole loop: product intent, UX, implementation, and long-term maintenance.
Previously a lead engineer at athenahealth, where I owned features across a patient payments platform at scale, and a frontend contractor at Apple, where I built internal tooling that turned user actions into test automation code.
That experience shapes how I approach contract work: I write systems that are clean enough to hand off, reliable enough to trust, and documented well enough for the next engineer.

Have a project in mind?

I'm taking on new freelance and contract engagements — React, TypeScript, full-stack, API design, AI integration, or greenfield builds. I typically respond within 24 hours.
