I am Christian a professional PCB design and embedded hardware engineer specializing in reliable, production ready electronic hardware. I help startups and developers turn circuit concepts into clean,...
Sobre este Serviço
Got an ESP32 hardware project that needs rock-solid code, stable connectivity, and clean cloud integration? I will write, optimize, and debug custom firmware tailored for your exact IoT use case.
What is included in this service:
* Custom ESP32 C++/Arduino or ESP-IDF firmware development
* WiFi, Bluetooth / BLE, and MQTT / HTTP client communication
* WebServer, OTA (Over-The-Air) update, and captive portal setup
* Sensor interfacing (I2C, SPI, UART, ADC, GPIO) & power optimization
* FreeRTOS multi-threading for fast, non-blocking execution
* Clean code structure with detailed setup documentation
How the process works:
1. Requirements Review: We lock down your exact sensors, pinouts, and desired communication protocols before coding.
2. Development & Testing: I write modular code and test it on real hardware or simulation environments.
3. Delivery & Handoff: You receive full source code, library dependencies, and clear compilation instructions.
Whether you need a simple sensor node or a full enterprise IoT device connected to AWS IoT, Blynk, or a custom dashboard, let's build it right.
Message me before ordering to confirm project scope and hardware compatibility!

Perguntas frequentes
Which development framework do you use?
I primarily write in Arduino C++ for quick deployment or ESP-IDF (C/C++) for heavy, low-level FreeRTOS performance requirements.
Do I get the complete source code?
Yes, every order includes 100% full, unencrypted source code ownership and list of library dependenci
What happens if I find a bug in the code after the order is completed?
If any bug or issue arises that deviates from our original agreed project scope, I will fix it free of charge even after order completion. Revisions cover bug fixes and adjustments within the original scope. New feature additions outside the original agreement can be added as a custom gig extra.
Can you help me connect my ESP32 to cloud platforms like AWS IoT, Blynk, or Adafruit IO?
Absolutely. I configure secure communication protocols including MQTT (with TLS/SSL encryption), HTTP/REST APIs, and WebSockets. Whether you use AWS IoT, ThingsBoard, Firebase, Blynk, or a custom dashboard, I can handle full integration.
What do I need to provide before placing an order?
To ensure a smooth build, please provide your target board pinouts, datasheets or links for all connected sensors/modules, your desired communication protocol (WiFi, BLE, MQTT, etc.), and a clear functional breakdown of what the system should do.
