I will develop custom firmware for esp32, stm32, and arduino embedded systems
Embedded Systems Engineer, ESP32, Arduino, IoT Developer
About this Gig
Are you launching a new hardware product or IoT project but struggling with buggy code, race conditions, or unoptimized memory handling?
Poorly written firmware can cause hardware lockups, severe battery drain, and unsecure data leaks. Your physical prototype requires professional-grade, asynchronous firmware architecture built to operate flawlessly under tight hardware constraints.
I provide end-to-end Embedded Systems development, writing clean, memory-optimized C/C++ code for major microcontrollers to keep your device responsive and stable.
Chipsets & Frameworks Supported:
STMicroelectronics: STM32 (HAL, LL, CubeIDE)
Espressif Systems: ESP32, ESP8266 (ESP-IDF, Arduino Core)
Atmel/Microchip: AVR, PIC, Arduino ecosystems
Core Features:
Real-Time Multi-Tasking via FreeRTOS / RTOS environments
Wireless Protocols: BLE (Bluetooth Low Energy), Wi-Fi, Mesh Networks
Wired Protocols & Drivers: I2C, SPI, UART, CAN Bus, Modbus
Hardware Integration: Sensor calibration, display interfaces, motor controls
Deep-Sleep & Ultra-Low Power Management Optimization

FAQ
Do I need to mail you my physical prototype hardware for development?
In most cases, no. As long as you provide your exact circuit schematics, wiring pinout sheets, and detailed component datasheets, I can emulate or utilize my in-house development boards (STM32/ESP32 matrices) to build and thoroughly flash-test your firmware.
Can you help adapt Arduino code into native, industry-grade STM32 C code?
Yes, absolutely. If your product is moving past the hobby prototype phase, I can rewrite bloated Arduino prototype libraries into native, efficient, register-level C code using STM32 CubeIDE to optimize chip memory and execution speeds.
What do you require from me to begin writing the firmware?
I need your exact microcontroller model number, complete datasheets for any sensors or actuators attached to it, a clear schematic or pin-connection diagram, and a text walkthrough of how your device is supposed to work.
