I will develop professional esp32 and stm32 embedded iot firmware
About this Gig
Tired of buggy firmware, memory leaks, and quick Arduino patches that fail in production?
I am an Embedded Software Engineer with 5 years of commercial experience building reliable, memory-efficient firmware for industrial and consumer products. I have successfully shipped real-world devices, including biometric terminals, thermal printers, and IoT systems.
What I Deliver:
- Microcontrollers: ESP32 (ESP-IDF), STM32, AVR, Jieli (JL) SDK
- Architecture: FreeRTOS multitasking, custom drivers, and memory optimization
- Connectivity: BLE 5.0, Wi-Fi, USB, MQTT, and secure networking
- Storage & Peripherals: NVS, LittleFS, sensors, RFID, and face recognition
- Lifecycle: Secure bootloaders, OTA updates, and rigorous debugging
Why Choose Me:
- Production-Ready Code: Clean, modular, and fully documented C/C++ source code
- Commercial Quality: Built for stability, edge-case handling, and low power
- Complete Support: Clear step-by-step build, flash, and integration instructions
Stop risking hardware failures with amateur code. Send me your schematics, requirements, or MCU details today, and let's bring your embedded product to life reliably!

FAQ
Can you help fix or complete existing code?
Yes, I can debug and improve existing code or help you finish an ongoing project.
What do I need to get started?
You just need a rough idea or project description. If you're using specific hardware (e.g. sensors, displays, modules), let me know the exact components.
Which IoT SOC do you support?
I work with ESP32, ESP8266, and Jieli. If you are using a different microcontroller, feel free to contact me first.
What information do I need to provide?
Project requirements, hardware specifications, communication interfaces needed, and any existing schematics or datasheets if available.
Do you provide source code and documentation?
Yes. All deliverables include well-commented source code. Documentation is provided based on project scope.
Do you work on custom embedded projects?
Yes. I work on custom embedded projects based on your specific requirements. Please share your project details before ordering so I can confirm feasibility.
Do you offer revisions?
Yes. Revisions are covered within the agreed project scope. Any additional requirements outside the original scope will be discussed separately.
