- Integrating Supabase, Firebase, RevenueCat, Stripe, OpenAI, and other third-party services
- Building AI-powered mobile features such as chat, analysis, content generation, voice interaction, and automation
- Improving existing apps, fixing production issues, and preparing them for release
Tech stacks I work with:
