I will debug and fix your arduino or esp32 code and firmware
I build your ideas into real hardware: RF, PCB, ESP32, Arduino, KiCad, Analog
I'm an embedded electronics student who actually owns the hardware I work with: ESP32, Arduino, sensors Analog electronics & RF modules.
I design PCBs in KiCad, develop firmware in C/C++, and work wit...
About this Gig
Your Arduino or ESP32 project worked perfectly until it didnt.
Random freezes, sensor failures, timing issues, variable overflows, or communication problems with BLE, UART, I2C, SPI... These bugs can waste days or even weeks of your time.
I specialize in debugging and fixing Arduino and ESP32 firmware fast. I work directly on real hardware (not just in simulation) and always deliver clean, stable, and documented code.
I can help with:
- Sensor integration and calibration
- Communication protocols (BLE, I2C, SPI, UART, etc.)
- Power optimization and long-term stability
- Timing conflicts and interrupts issues
- Code review and refactoring
I thoroughly test every fix on physical hardware before delivery. Most projects are resolved within 24-48 hours.
Got a stuck project? Send me the details and lets get it working again quickly and reliably.

FAQ
What information do you need to get started?
Your code files, a description of the bug or unexpected behavior, and the list of components/sensors involved. The more context you give, the faster I can fix it.
Do you work with code written by someone else?
Yes. I regularly work with existing codebases, even messy or undocumented ones.
What if you can't fix the bug?
If I can't identify and fix the issue, you don't pay. I'll let you know upfront if something is out of scope.
Do you have the hardware to test my project?
Yes. I own Arduino boards, ESP32 modules, and a range of common sensors. I test all fixes on physical hardware before delivery.
Can you handle large or complex projects?
For projects beyond the Premium scope, message me before ordering and I'll give you a custom quote.
What is your typical turnaround time?
Most standard bugs are fixed and delivered within 24 to 48 hours. Complex issues may take 3-5 days. I always communicate expected timelines upfront.
Do you offer code review only?
Yes, I can review your code and give you detailed feedback + recommendations without necessarily modifying it.
