I will develop custom esp32 iot firmware using espidf and arduino
About this Gig
Need reliable ESP32 firmware that actually works with your hardware and project requirements?
I am an Embedded Firmware Engineer with 5 years of experience building stable ESP-IDF and Arduino IoT solutions.
Whether you are building a new smart device from scratch or debugging an existing board, I deliver clean, optimized C/C++ code designed for stability and real-time performance.
Expertise & Services:
- Frameworks & OS: ESP-IDF, Arduino, FreeRTOS task management, memory & PSRAM optimization
- Connectivity: Wi-Fi, BLE 5.0, TCP/IP, WebSockets, MQTT, STOMP protocols
- Advanced Features: Face detection/recognition (ESP-DL), camera integration (OV3660, GC0308), and LVGL
- Peripherals & Sensors: Custom hardware drivers, I2C, SPI, UART, barcode scanners, and data loggers
- Maintenance: Secure OTA updates, GATT table configuration, and rigorous debugging
You'll receive clean, structured C/C++ firmware with proper hardware integration, debugging, optimization, and clear documentation.
Send me your project requirements, schematic, hardware details, or existing code, and let's build a robust solution for your hardware today.

FAQ
Can you help fix or complete existing code?
Yes, I can debug and improve existing code or help you finish an ongoing project.
Can you help me understand the code you deliver?
Yes! I always include comments and will answer your questions after delivery.
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.
Can you add a web interface or GUI?
Yes! I can build simple web interfaces (ESPAsyncWebServer, SPIFFS, etc.)
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.
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.
Do you provide source code and documentation?
Yes. All deliverables include well-commented source code. Documentation is provided based on project scope.
Can you design PCB along with firmware?
Yes. I provide both PCB schematic design and firmware development as a complete embedded solution.
What information do I need to provide?
Project requirements, hardware specifications, communication interfaces needed, and any existing schematics or datasheets if available.
Do you offer revisions?
Yes. Revisions are covered within the agreed project scope. Any additional requirements outside the original scope will be discussed separately.
