You will get Embedded firmware, tested, optimized, and ready to flash
Top Rated
Project details
I develop reliable and efficient firmware for STM32, ESP32, and IoT devices, helping you turn hardware into a fully functional product. With experience across wearables, automation, and wireless systems, I deliver firmware that is robust, optimized, and ready to use.
What you get:
Clean, modular, and well-documented code
Peripheral drivers (UART, SPI, I2C, ADC, PWM, GPIO, etc.)
RTOS or bare-metal (FreeRTOS, ESP-IDF)
Wireless connectivity (BLE, Wi-Fi, LoRa)
Power optimization for battery life
Debugging and performance tuning
Ready-to-flash binaries + documentation
Process:
Review your requirements and hardware.
Develop and test modular firmware.
Deliver code, binaries, and usage instructions.
As a Top Rated Plus freelancer with proven results in embedded projects worldwide, I ensure firmware that works reliably the first time.

Over the past 6+ years, I have delivered 15+ commercial products across IoT, wearables, medical devices, and industrial systems.
• Built a rock fall detection system (Impact Sentinel) with FCC/CE certification, 10-year battery life, and 10km wireless range, now deployed for rail safety.
• Designed a LoRaWAN-based wrist tracker for emergency situations, deployed across 6,000+ units.
• Developed an underground mine safety system combining UWB positioning, LoRa communication, and collision avoidance for heavy machinery.
• Designed the hardware and firmware for EKKO, an award-winning speech therapeutic device, and managed production of 100+ units.
• Created multiple ultra-low-power IoT devices with multi-year battery life using STM32, ESP32, and custom RF circuitry.
I work with STM32, ESP32-S3, and nRF52/53 families. Experienced with LoRaWAN, NB-IoT, BLE, UWB, sub-GHz RF, CAN, and Ethernet. PCB design in Altium Designer and KiCad and EasyEDA, production-oriented, compact (some as small as 30mm x 30mm), and built for manufacturability.
I do not take academic assignments. I work with clients who are building real products for real markets.
If you have a product idea or an existing design that needs to move forward, send me a message with a brief description and I will let you know how I can help
