I will develop custom esp32 arduino iot firmware with wifi mqtt and sensor integration
About this Gig
YOUR ESP32 / ARDUINO PROJECT DESERVES FIRMWARE THAT ACTUALLY WORKS
Tired of half-working code from Stack Overflow? Struggling to get your sensors talking to the cloud? I will handle the firmware so you can focus on your product.
I am an embedded systems engineer with real internship experience building production-grade IoT firmware using ESP32, MQTT, and sensor integration pipelines.
I SPECIALIZE IN:
- ESP32, Arduino, STM32 firmware development
- WiFi, BLE, LoRa, MQTT cloud connectivity
- Sensor and peripheral integration via I2C, SPI, UART
- Real-time data logging and remote control systems
- Hardware debugging using serial logs and logic analyzers
- PCB bring-up and power rail verification
REAL EXPERIENCE:
At my internship I built modular firmware for ESP32 IoT nodes deployed in live environments. Sensor data collection, MQTT cloud pipelines, interrupt-driven communication, and PCB-level debugging. This was not classroom work. This was production.
MESSAGE ME FIRST:
Send me your project details and I will give you an honest answer about what I can build for you.
No fluff. Just working firmware.

FAQ
Do I need to send you my hardware?
No. I develop and test firmware on my own hardware and deliver the complete source code. You just flash it to your device.
Can you work with my existing code?
Yes. I can review, debug, and extend your existing firmware. Just share the code and explain what is not working.
What information do I need to provide?
Just tell me what you want to build. Which microcontroller, which sensors, and what the end goal is. I will ask questions and we figure out the details together.
