About this Gig
If you need reliable BLE firmware for your device, youre in the right place.
I develop custom Bluetooth Low Energy firmware for ESP32 and Nordic nRF52 devices, focused on stable connections, efficient power usage, and seamless mobile integration.
Most BLE issues come from poor GATT design, weak pairing logic, or unstable communication. I solve that by building structured firmware with clean GATT services, optimized data flow, and strong connection handling.
What I can build for you:
Custom BLE firmware (ESP32 BLE, nRF52 firmware)
GATT services and characteristics design
Secure BLE pairing and bonding
Data transmission between device and mobile app
Low power optimization for battery devices
OTA-ready firmware architecture
Debugging unstable BLE connections
I design firmware that works in real-world conditions, not just in testing.
Whether youre building a wearable, IoT device, smart product, or mobile-connected hardware, I ensure your BLE communication is stable, efficient, and production-ready.
