Industry Experience

Software & Internet
    Full-Stack AI Application Development — Next.js, Supabase & OpenAI Integration

    Developed and deployed a production-grade AI SaaS web application using Next.js 14 App Router, React, TypeScript, and Tailwind CSS.

    The Problem
    A founder had three weeks before investor demo day to validate a fitness subscription model. They needed offline workout logging, streak mechanics, and Apple Health integration — but had no mobile app and no time to hire a team.

    What I Built

    A cross-platform fitness tracker using Flutter and Firebase. Users log workouts without internet, maintain streaks with local notifications, and sync biometrics through Apple HealthKit. RevenueCat handles the subscription tiering.

    The Outcome

    • 3 weeks from first call to TestFlight beta
    • 2,400+ beta signups in the first 30 days
    • 4.8 star rating on App Store at launch
    • Founder secured pre-seed funding after demo day

    My Role

    Sole mobile developer. Scoped the MVP, architected the offline-first data layer, built the UI, integrated HealthKit, and handled App Store submission including the initial rejection and resubmission.
