About Kasphyn:

We are building Kasphyn — an EMG + IMU wearable device for responsible fitness enthusiasts. The device reads real-time muscle activation data via Bluetooth Low Energy (BLE) and delivers AI-powered coaching through a React Native mobile app.

What You Will Do (End-to-End Ownership):
Build and maintain our React Native (Expo) mobile app — screens, navigation, state management, animations
Implement and debug BLE data streaming from our custom hardware device to the app
Work with real-time sensor data (EMG + IMU signals) — parsing, filtering, visualization
Integrate with backend — auth, real-time database, edge functions
Build data pipelines for our AI coaching layer




Fix bugs across the stack — firmware-adjacent issues, app crashes, performance bottlenecks
Ship features rapid. We prototype in days, not sprints.

Tech Stack:
React Native (Expo) + TypeScript + NativeWind
Zustand (state management)
react-native-ble-plx (Bluetooth LE)
Supabase (PostgreSQL, Auth, Realtime)
react-native-svg, react-native-reanimated
Git + GitHub + Cursor/Claude Code workflows

Pay: From ₹30,000.00 per month
