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.

Islamabad, Pakistan - 7:45 pm local time
I design and build electronic products from schematic to manufacturing: PCB design, firmware development, RF integration, and production support. My devices are FCC/CE certified and deployed in the field, including a rail safety sensor with 10-year battery life and 10km range, a 10,000-unit wearable production run, and an underground mine collision avoidance system.

Over the past 6+ years I have delivered 15+ commercial products across IoT, wearables, medical devices, and industrial automation:
• Impact Sentinel, a rock fall detection system for railway safety. FCC/CE certified, 10-year battery life, 10km wireless range.
• A LoRaWAN wristband for emergency alerts and location tracking, with 10,000 units manufactured and deployments ongoing.
• An underground mine safety system combining UWB positioning, LoRa, CAN, and Ethernet for machine-to-person collision avoidance.
• EKKO, an award-winning speech therapy device. I designed the hardware and firmware and managed production of 100+ units.
• Multiple ultra-low-power IoT devices with multi-year battery life on coin cells, some as small as 30mm x 30mm.


What I can do for you:
• Schematic capture and PCB layout in Altium Designer, KiCad, or EasyEDA, designed for manufacturability from the first revision
• Firmware development in C/C++ for STM32, ESP32-S3, and nRF52/53, bare metal or RTOS
• Wireless design: LoRaWAN, NB-IoT, BLE, UWB, and sub-GHz RF with custom antenna matching
• Battery life optimization for devices that need to run for years, not months
• Prototype bring-up, testing, certification support, and transition to volume production

If you have a product idea or an existing design that needs to move forward, send me a brief description and I will tell you exactly how I can help.

Steps for completing your project

After purchasing the project, send requirements so Khuram can start the project.

Delivery time starts when Khuram receives requirements from you.

Khuram works on your project following the steps below.

Revisions may occur after the delivery date.

Professional firmware Development.

I will develop firmware for commercial products.

Review the work, release payment, and leave feedback to Khuram.
