About Me
Hello! I'm Santanu Dutta, a passionate full stack developer with expertise in the PERN stack, Next.js, PostgreSQL with Prisma, React Native, and Supabase. I specialize in building responsive applications that combine professional design with powerful functionality. Currently expanding my skills in DevOps practices. I'm committed to continuous learning and pushing boundaries to deliver innovative solutions in modern development.
Work Experience
- Developed an iOS app blocking system in React Native (Expo) that lets users block and temporarily unlock apps for a user-selected duration, with automatic relocking using the Device Activity Monitor Extension. Customized the iOS Shield UI via Shield Configuration Extension and handled action interactions with the Shield Action Extension.
- Built a full timezone-handled recurring notification system for a mobile app using Supabase Edge Functions, cron jobs, and Expo Push Notification Service.
- Developed an AI-powered automation system where admins upload promotional PDF leaflets, extract images using pdfjs-dist, and process them with OpenAI OCR to extract product names, prices, discount percentages, retailer details, and promotion timelines, then automatically generate promotion entries.
- Implemented an AI voice interaction system that adapts to user-selected moods, leveraging the OpenAI Realtime API for speech processing and response generation, and ElevenLabs for natural voice synthesis.
- Built a real-time chat system with messaging, emoji reactions, thread replies, and moderation features (ban functionality), supporting both mobile and web platforms.
- Developed a mapping system where users upload GPX files or Google Maps point links, extract coordinates, and display them on an interactive map using Mapbox API with zoom and drag controls.
