FAQ
I just need a bug fixed in my existing firmware. Can you help?
Yes, send me the code and describe the issue. Small fixes usually fall under the Basic package.
My MCU isn't ESP32 or STM32 — can you still help?
Probably yes. I've worked on PIC, AVR, NXP LPC2129. Message me first and I'll confirm
Will the code work on my actual hardware, not just an emulator?
Always. I write firmware for real hardware. I'll need your datasheet or schematic for hardware-specific work.
Can you add Wi-Fi OTA updates to my existing ESP32 project?
Yes — that's a Standard or Premium job depending on your current codebase. Message me with your code.
