Selected Work
Production deployments — not concepts. Each project below is live or shipped to its target platform.
A workout timer built by athletes, for athletes.
Code4U built a cross-platform app in React Native with native iOS polish, plus a web version on Vercel. Covers AMRAP, For Time, EMOM, TABATA, and Complex timers, all the standard WOD formats with saveable favourite timers and mobile-first ergonomics for gym environments.
The ultimate word-crafting adventure.
We designed and launched an interactive word-forging game from concept to deployment. Seven letters glow like embers; players hammer them into five unique five-letter words, racing toward the elusive Final Word of the day. Built with HTML, CSS, JavaScript, and Node.js, hosted on AWS S3 + CloudFront with strict free-tier budgeting.
