I build production full-stack software and Cloudflare-native products.

I've spent 10 years building and shipping production software, independently and with distributed teams. I currently run an independent engineering practice delivering client builds, open-source tools, and productized SaaS templates.

For clients on Upwork and Contra, I've delivered 10+ e-commerce, professional-service, and internal-tool projects using React, Next.js, Firebase, and Cloudflare—with zero missed deadlines.

I built and maintain WaiChat, an open-source AI chat app on Hono, Cloudflare D1, and Workers AI. Across 5+ alpha releases, I designed its deployment pipeline, resolved a D1 migration race condition, and used three GitHub Actions workflows to bring failed deploys near zero.

At Züs (0Chain), I led frontend work across six products and 30+ engineers, reviewed most merged pull requests, and closed 1,500+ across the organization. I also owned Vult end to end across web, iOS, Android, Mac, and Windows teams.
