I will make esp32 and arduino firmware for sensors and iot projects
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
You have an idea, a sensor, or a module but no working firmware yet.
Getting a new sensor or module talking correctly to an Arduino or ESP32 isn't always straightforward. Wrong wiring, unclear datasheets, timing issues, protocol mismatches (I2C, SPI, UART, BLE)... it's easy to lose hours just getting a single component to respond reliably.
I specialize in building custom Arduino and ESP32 firmware from scratch, based on your specs or hardware. I work directly on real hardware (not just in simulation) and always deliver clean, commented, and tested code.
I can help with:
- Single or multi-sensor integration
- IoT communication (BLE, WiFi, LoRa, MQTT)
- Custom drivers for sensors and modules
- System architecture for multi-component projects
- Firmware optimized for stability and power efficiency
I test every project on physical hardware before delivery, so you get firmware that actually works not just code that compiles.
Got a sensor, module, or IoT idea that needs to come to life in firmware? Send me the details and let's build it.

FAQ
Will you test the firmware on my exact hardware, or a similar one?
I test on hardware I own; common ESP32/Arduino boards and sensors. If I have your exact part, I test on it directly. If not, I'll tell you upfront: I can usually still build and test with an equivalent module, but final validation on your unit is on your side.
Can I add more sensors than what's included in my package?
Yes, via the "Additional sensor/module" extra. Note that adding sensors this way covers individual drivers; if you need multiple sensors working together with a unified architecture, the Standard or Premium package is a better fit.
Do you provide documentation with the code?
Basic and Standard packages include clean, commented code but not a separate documentation file. Detailed documentation is included in the Premium package, or available as an extra on any package.
What if my project doesn't fit any of the packages?
Send me your specs first. If your project needs something outside these packages (larger scope, different sensor count, custom requirements), I'll send you a custom offer.
Which boards and sensors do you support?
Arduino (Uno, Nano, Mega, etc.) and ESP32. For sensors and modules, most I2C/SPI/UART/BLE components are supported: if you're unsure whether yours is compatible, message me before ordering.
