At C4Micro Tech, I develop cross-platform Flutter apps and web dashboards for connected hardware. I built BLE device-control and OTA firmware-update flows, along with real-time video, telemetry, and sensor-monitoring features.

At GRID Systems (Pvt) Ltd, I revamped a customer portal with Angular, NgRx, and RxJS and migrated a legacy AngularJS codebase to Angular 9. I also built a WebSocket chat application and portals for telemedicine appointments and surveys.
