About this gig
Stuck on an Arduino or ESP32 project? Need sensor integration, serial communication, or IoT functionality? I'll write clean, well-tested embedded C/C++ code that runs on your hardware.
I've built IoT systems with WiFi, MQTT, multiple sensors, and real-time data logging so I know what actually works in practice, not just in simulation.
What I work with:
- Arduino (Uno, Nano, Mega) and ESP32/ESP8266
- Sensors DHT, ultrasonic, IR, MPU6050, BME280 and more
- Communication UART, I2C, SPI, WiFi, Bluetooth
- IoT platforms ThingSpeak, Blynk, MQTT brokers
- Motor control, relay switching, LED arrays
Every delivery includes working .ino or .c files plus a short explanation of how to run it. Not sure if your project fits? Message me first I'll give you a straight answer.

Hi, I'm Joel — an Electronics & CS engineering student with hands-on experience in Python automation, embedded systems, and FPGA/Verilog design.
I've built web scrapers, data processing scripts, Arduino and ESP32 IoT projects, and Verilog modules for real hardware targets. I know what it's like to be a student working on tight deadlines — so I keep my communication clear and my deliverables clean.
Whether you need a Python script that saves you hours, an embedded project done right, or Verilog code that actually synthesizes — I've got you covered.
Let's build something.
FAQ
What hardware information do you need to get started?
Just tell me your board model and sensor model numbers. I don't need the physical hardware — I write and test the code based on datasheets and specifications.
Will the code work directly on my board?
Yes — I write for your specific hardware. If something doesn't work after uploading, message me and I'll fix it free of charge.
Can you help debug existing code that isn't working?
Yes — send me your code and describe what's going wrong. I can debug and fix it, just select the appropriate package based on complexity.
Do you support other microcontrollers besides Arduino and ESP32?
I primarily work with Arduino and ESP32 but can also help with STM32 and other ARM-based boards. Message me with your specific board before ordering.
