About this Gig

End-to-end embedded prototype: schematics, PCB, and working firmware.

Gig Description

If youre serious about building a hardware product, you need more than a random breadboard and copied code. I help you move from idea working prototype ready for small-batch manufacturing.

I work on embedded systems, IoT devices, controllers, and sensor-based products, covering both electronics and firmware.

What I can do for you:

  • Concept review and architecture selection
  • ESP32 / ESP8266 / STM32 / Arduino / Raspberry Pi-based designs
  • Schematic design (sensors, power, communication, protection)
  • PCB design (single/multi-layer) ready for fabrication (Gerber + BOM)
  • Firmware development:
  • Sensor reading, actuators, motors, relays, pumps, valves
  • UART / I²C / SPI / RS-485 / Modbus
  • Wi-Fi / BLE / GSM (basic cloud/API integration)
  • Prototyping guidance (JLCPCB/PCBWay etc. what to order and how)
  • Testing logic: self-tests, status LEDs, error reporting
  • Basic documentation: pinout, connection diagram, and firmware build steps
