Next.js + React Native + Expo · UI/UX Engineer · 20+ years of SWE · BS & MS in Bioinformatics age 19 · Doctor of Physical Therapy
I’m Dr. Derek Austin: an AI-native senior full-stack TypeScript product engineer and UI/UX engineer. Since 2019, I’ve specialized in TypeScript, React, Next.js, Tailwind CSS, and Node.js; since 2023, I’ve also specialized in React Native + Expo for iOS and Android.
I understand the product, decide what matters, design the system, build the software, make releases repeatable, verify the result, and explain the tradeoffs clearly.
I orchestrate AI coding agents using functional specifications, technical architecture, and persistent project context, then verify their output through human review, automated testing, and manual QA.
My engineering loop is Plan → Build → Test → Reflect: decide what matters, build it, prove it works, and use the result to improve the next cycle.
I own products across web, iOS, and Android, making deliberate decisions about state, UI, testing, and releases on every surface. I define clear requirements for architecture, accessibility, performance, testing, and maintainability before implementation.
Contact me if you need a high-autonomy code owner who can define, architect, build, verify, release, observe, and iterate a product in production.

AI-Native Senior Full-Stack SWE · UI/UX Engineer · Self-Employed | TypeScript, React, Next.js, Tailwind CSS, Node.js, React Native + Expo
I help startup founders and small teams build full-stack TypeScript products, including privacy-sensitive and regulated applications, using AI-native engineering without the tech debt of vibe coding.
ContactI’m actively seeking a long-term, full-time remote role as a full-stack SWE and code owner at a US startup.
★I build and ship full-stack TypeScript products across web, iOS, and Android with Next.js, React Native, and Expo, owning EAS Build/Submit, OTA updates, and releases to the App Store and Google Play.
★As a code owner, I take products from functional specification through production using deterministic architecture and AI-native workflows grounded in persistent context, human code review, automated testing, and manual QA.
★I have delivered production-ready MVPs in under 3 months, including a 90% reduction in network payloads and a 60× improvement to a key data visualization’s load time.
