I will write professional esp32 firmware and iot embedded programming
About this Gig
Welcome to professional firmware development for the ESP32 and IoT ecosystems!
Need reliable, well-structured code for your ESP32 project? I am an experienced embedded systems developer specializing in writing optimized firmware for IoT devices, industrial automation, and smart hardware applications. Whether you need a simple prototype or a production-ready application, I deliver clean, commented code tailored to your exact hardware setup.
What I Can Implement for Your ESP32:
- Wireless Connectivity: WiFi (HTTP, MQTT, WebSockets) and Bluetooth (BLE, Classic).
- Peripherals & Interfacing: Hardware timers, PWM control, I2C, SPI, UART, and parallel RGB/DPI display interfacing.
- Sensors & Actuators: Real-time encoder reading, sensor data filtering, and synchronized stepper/motor driver logic.
- Data Processing: Efficient memory management strategies, including parsing complex JSON files (up to 6KB+) without crashing.
- Frameworks: Arduino.
What You Will Get:
- Fully functional, clean, and well-commented source code files.
- A clear circuit connection diagram (if required to help you wire your prototype).
- Step-by-step documentation on how to upload and test the firmware.

FAQ
Which development environments or frameworks do you use for ESP32 programming?
I write firmware using either the Arduino framework using PlatformIO
How do you handle complex multitasking or real-time operations on the ESP32?
For advanced applications, I utilize FreeRTOS to manage multiple tasks across the ESP32's dual cores efficiently. This ensures time-critical operations—like high-speed sensor readings or hardware encoder tracking—run smoothly.
How do you guarantee the code will work perfectly on my custom hardware setup?
I test all written logic on physical ESP32 development hardware on my end to ensure the core code is functionally sound. However, because every custom board is unique, I provide full, step-by-step remote support while you flash and test the code on your actual physical setup.
