Project details
Get production-grade STM32 firmware engineered directly in STM32CubeIDE using Embedded C/C++ with HAL, LL drivers, or FreeRTOS. Whether you need bare-metal peripheral drivers, interrupt-driven communication pipelines, or real-time multitasking architecture, I deliver clean, scalable, and memory-optimized code.
Why choose this service:
• Optimized Peripheral Drivers: Precise setup for GPIO, TIM, ADC, DAC, PWM, RTC, and DMA registers using HAL/LL drivers.
• Industrial Communication Protocols: Robust implementations for UART/USART, SPI, I2C, RS485 (Modbus), and CAN Bus.
• FreeRTOS Multitasking: Deterministic task scheduling, queues, semaphores, and power-saving sleep modes for complex systems.
• Robust Architecture: Defensive memory management, Watchdog timers (IWDG/WWDG), and fault handling.
I review your target MCU datasheets, IOC pinout configurations, or custom schematics upfront to deliver fully compiled projects with source code and flashing documentation. Select a tier or message me to get started!

ESP32-S3 Firmware Developer for IoT Project
Muhammad did an excellent job delivering the ESP32 firmware and met all project requirements. His communication was clear, professional, and timely throughout the process. The code quality and reliability were exactly what I was looking for, and he was very responsive to feedback. I would definitely work with him again and highly recommend him.

ESP32-S3 Custom Board Speech Output Development
Tabish did a great job on this project. That's why we expanded the project after the first task and had him program additional components. He replicated the hardware we used for development and was able to create code that could be used immediately. He communicated very well, familiarized himself with new areas, and developed solutions. Highly recommended!

Job Success
Karachi, Pakistan - 2:36 am local time
I build reliable, low-power firmware that turns hardware prototypes into production-ready devices and I guide clients through every stage of product development, from early proof-of-concept to final manufacturing firmware.
I work bare-metal and with FreeRTOS on STM32, Nordic nRF52, and ESP32 platforms. My focus is clean, deterministic code: real-time sensor processing, robust wireless stacks (BLE, Wi-Fi, LoRaWAN), and efficient peripheral drivers (SPI, I2C, UART, CAN, Modbus) that don't crash under load.
What I do:
1. Firmware architecture and bring-up for custom PCBs
2. End-to-end product development support from prototype to production
3. Low-power optimization and real-time sensor fusion
4. Wireless IoT device development (BLE, Wi-Fi, LoRa)
5. Debugging broken codebases and protocol troubleshooting
6. BSP/HAL and driver development
If you need firmware that works reliably in the field , not just on the bench , send me your requirements and let's talk.
Steps for completing your project
After purchasing the project, send requirements so Muhammad can start the project.
Delivery time starts when Muhammad receives requirements from you.
Muhammad works on your project following the steps below.
Revisions may occur after the delivery date.
MCU Pinout & Datasheet Review
I review your STM32 part number, clock configuration, IOC pinout mapping, and schematic to verify hardware setup.
STM32CubeIDE & Driver Development
I write modular Embedded C/C++ code, setting up HAL/LL drivers, interrupts, DMA channels, and state machines.
