I'm Engr. Badar Hasnain Shehki — a Computer Engineering graduate from NUST and a working Firmware Engineer at Quickgen Technologies, Islamabad.
I specialize in firmware development for ESP32, STM32, and NRF52840 microcontrollers,
and I build the Flutter mobile apps that connect to them. My code runs in real commercial IoT products — not just hobby prototypes.
What I deliver: BLE firmware, sensor integration (I2C/SPI/UART), cloud connectivity (Azure IoT, AWS, MQTT), cross-platform Flutter apps, PCB debugging, and full technical documentation. Let's build something great.

FAQ
Can your Flutter app connect to my hardware device via Bluetooth?
Yes — this is my specialty. I use flutter_blue_plus and flutter_reactive_ble to connect to BLE devices. I understand GATT services, characteristics, and notifications at the firmware level, so I can build apps that communicate reliably with your hardware
Will the app work on both Android and iOS?
Yes. Flutter produces a single codebase that runs natively on both platforms. I will test on real Android devices. iOS builds require an Apple developer account for App Store submission, but I can provide a TestFlight build
Do you provide the source code?
Yes, 100%. You will receive the full Flutter source code with a README, setup instructions, and architecture notes (Standard/Premium packages).
Can you integrate my existing REST API or backend?
Absolutely. Share your API documentation and I'll build a complete Flutter frontend that integrates with your backend via HTTP/REST or WebSockets.
Can you replicate a design from Figma or a screenshot?
Yes. If you have a Figma design file or reference screenshots, I can implement them precisely in Flutter. Provide them when placing the order.
