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 use frontier LLMs to increase velocity and quality, not to outsource judgment. I orchestrate AI coding agents using functional specifications, technical architecture, and persistent project context, then verify their output with my own 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.
Inside that loop, my Five-Step Forge is the execution protocol: 1PLAN → 2CHECK → 3WRITE → 4CHECK → 5RUN. The loop describes how I work; the forge defines the checkpoints that keep agentic work reliable. Before the forge, 0LIST audits canonical ownership and impacted files.
I maintain language-specific coding standards and 40 anti-slop engineering pillars so architecture, accessibility, performance, testing, and maintainability are explicit requirements instead of last-minute cleanup.
This approach lets me own products end-to-end across four product surfaces: desktop web, mobile web, iOS, and Android. On every surface, I make deliberate decisions about state, UI, testing, and releases.
Contact me if you need a high-autonomy code owner who can take a product from functional specification through production release.

AI-Native Senior Full-Stack SWE · UI/UX Engineer · Self-Employed | TypeScript, React, Next.js, Tailwind CSS, Node, 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 technical debt of vibe coding.
Inquire About AvailabilityI’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 deliver production-ready MVPs in under 3 months without sacrificing performance: I have cut network payloads by 90% and reduced a key data visualization’s load time from more than 10 minutes to under 10 seconds.
