• Built the personalized feed from scratch using Prisma ORM and PostgreSQL with behavioral scoring, daily cron aggregation, and topic-relevance ranking;
• Migrated the mobile app from Flutter to React Native and rebuilt deep linking, push notifications, and Google Sign-In across iOS and Android;
• Shipped unified authentication across web and native with Google OAuth, subscriptions, token refresh, session recovery, and payment-state transitions;
• Extracted SigNoz and OpenTelemetry into a shared workspace package so every microservice shipped with structured logs and traceable failures by default.

AI-powered infrastructure planning platform that aggregates real-time climate, hazard, and zoning data to support government infrastructure and land-use decisions through an interactive geospatial interface.
