MinMax is a B2B platform that helps businesses produce consistent marketing videos from reusable templates. I built the React Native client and a Firebase/Node.js backend, including Firestore data models and secure multi-tenant access patterns. I also implemented queue-driven workers for rendering and post-processing, and handled CI/CD and production deployments.

MultiPolls is a mobile survey app where users answer polls and earn rewards. I was brought in to rebuild the mobile app in React Native, turning an early MVP into a more scalable, production-ready codebase. I focused on core UX, performance, and reliability, and helped ship stable releases to Android and iOS.

VETRI was a Web3 nonprofit project that let users earn rewards for completing surveys while keeping control of their personal data. I worked mainly on the React Native app, including wallet/crypto integrations, offline-first encrypted storage (Realm), and the core UX. I also set up dev/staging/prod environments, automated translation exports to Weblate, and built a CI/CD pipeline for app builds and releases. The project was later shut down after limited market traction.
