I will write firmware for your arduino, esp32 or stm32 projects
Embedded System Engineer, Firmware and PCB Design
About this Gig
Need firmware that actually works reliably not just a prototype that
runs once on the bench?
I'm an embedded systems engineer offering firmware development across
three levels:
- Basic Arduino Projects sensor/actuator interfacing, simple automation logic, clean and commented sketches.
- Arduino Framework (ESP32/ESP8266/AVR) WiFi & MQTT connectivity,multi-peripheral integration, interrupt-driven, structured code.
- Native SDKs & IDEs STM32 (HAL/LL/register-level), ESP-IDF + FreeRTOS, bare-metal AVR for performance, memory efficiency, and production-grade firmware.
- Clean, documented code
- Explained, not a black box
- Tested before delivery
- Post-delivery support
Not sure which tier fits? Message me first I'll tell you honestly what your project actually needs.

FAQ
What microcontrollers/platforms do you work with?
rduino (AVR-based boards), ESP32/ESP8266, and STM32 — including register-level and HAL/LL programming on STM32, and ESP-IDF with FreeRTOS on ESP32.
Do you only write firmware, or can you help with the hardware side too?
Both — I also do PCB design, so if your firmware needs custom hardware or you're debugging a hardware-firmware interaction issue (timing, wiring, peripheral communication), I can help end-to-end.
Will I get the source code and be able to modify it later?
Yes, full source code is delivered along with comments/documentation so you (or another developer) can maintain it going forward.
Can you integrate cloud connectivity (MQTT, AWS IoT, etc.)?
Yes — I have experience with MQTT-based IoT connectivity and cloud integration for connected device projects.
What if my project doesn't fit neatly into one of these three tiers?
Message me before ordering — I'll scope it out and either point you to the right package or set up a custom offer.
