At Heizen, I architected the Medurun dispatch service so one driver claims each trip, and shipped its React Native apps and dashboards. I also shipped Evra’s React Native app and FastAPI API, with encrypted clinical fields and clinician authentication.

At United Protocol, I shipped web, desktop, and React Native clients, including an agentic mobile browser and voice agents. At WhatBytes, I improved rendering on a Svelte and Next.js app serving 70,000–100,000+ weekly users.
