Radhika J.

Mobile app developer with 9+ years building Android, iOS and Flutter apps, including IoT and Bluetooth (BLE) device apps, AI features, and OCR. Top Rated, 60+ completed jobs. If your app needs to talk to a device, read a document, or use AI to do something genuinely useful, I've most likely built something close to it before. RECENT WORK • BLE command-sync for a French pet-tech company's smart dog-training device. Fixed the Bluetooth reliability issues that had stalled their iOS launch. • AI soil-analysis feature for an AgriTech Flutter app. Pulls soil data by GPS location and turns it into plain-language reports for farmers. • AI photo-enhancement app that scores photo quality and recommends fixes automatically. • Field-inspection app with OCR and image upload for structured data capture. • Carpool app with live chat, real-time location tracking and ride matching. • Barcode and RFID-based inventory and tracking apps. • WearOS/watchOS apps connected to smart devices. WHAT I DO • Native Android (Kotlin/Java) and iOS (Swift), Flutter and React Native • BLE/Bluetooth, IoT device provisioning, RFID and barcode systems • OCR and document scanning (ML Kit), LLM integration (OpenAI, Claude) • Android enterprise: MDM/EMM, Samsung Knox, Device Owner provisioning • Firebase & Supabase, REST and real-time APIs, Play Store and App Store releases HOW I WORK You'll hear from me early if something is out of scope or behind schedule. You get regular commits, clear updates, and clean code your next developer can maintain. I'm comfortable working inside your existing repo and backend, or independently from a spec. Send me a short description of your app and what's blocking you, and I'll reply with how I'd approach it.
