I will program esp32 stm32 and arduino firmware for your project
Embedded engineer & electronics specialist with expertise in microcontrollers, PCB design, IoT, and firmware. I deliver professional, reliable, and optimized solutions tailored to your project needs.
About this Gig
Firmware that actually works on real hardware.
Hi, I'm Ali an embedded systems engineer who writes firmware for ESP32, STM32 and Arduino, and honestly, solving tricky problems is the part I enjoy most. I've shipped a battery-powered IoT product end-to-end (BLE, OTA updates, power management, sensors, display), so I know how to make firmware that's reliable in the field not just on the bench.
What I can do for you:
Sensor interfacing (I2C, SPI, UART, ADC) any sensor, any protocol
BLE / WiFi connectivity and device-to-phone communication
FreeRTOS multitasking, timers, interrupts, low-power modes
Displays & UI (LVGL), LEDs, motors, actuators
OTA firmware updates, debugging, and fixing your existing code
Bonus: I design PCBs too, so I understand your hardware deeply. Send me your schematic and I'll hit the ground running.
Stuck on a bug? Send it over solving it is my favorite part. Message me before ordering so we can scope it right. Let's build something that works!
FAQ
Do you offer simulation?
Yes, as an optional add-on. I simulate firmware for supported microcontrollers and components. Note: some hardware-specific timing, RF (WiFi/BLE) and analog behavior can only be verified on real hardware — I'll always tell you upfront what can and can't be simulated.
Which microcontrollers do you support?
ESP32 / ESP32-S3 (ESP-IDF & Arduino framework), STM32 (CubeIDE / HAL), and Arduino (AVR). Not sure which fits your project? Just message me.
Can you fix or improve my existing code?
Absolutely. Send me your repo or files and describe the issue — debugging is one of my favorite parts.
Do I need to send you physical hardware?
No. I develop and test the logic on my side, then we validate together. For tricky timing issues I may ask for serial logs or a short video.
Do I get the source code?
Yes, always. The full source code is yours to keep and modify.
Do you offer simulation?
Yes, as an optional add-on. I simulate firmware in Proteus or Wokwi for supported microcontrollers and components. Note: some hardware-specific timing, RF (WiFi/BLE) and analog behavior can only be verified on real hardware — I'll always tell you upfront what can and can't be simulated.
Can you also design the PCB or hardware?
Yes! PCB design is my other specialty (KiCAD / Altium). Message me and we can bundle hardware + firmware together.
