Freelance Firmware Engineer

Freelance-upwork
02.2024 - Current
  • ATtiny13A Multi-State Timer: Wrote AVR C firmware implementing PB1-triggered timing states (T1–T5 delays up to 250 min), PB2 pulse sequencing, and PB0 inverse-mirror output with EEPROM-backed parameters → https://github.com/alexhaya4/TimerControl13A
  • ESP32 Sensor Acquisition: Developed FreeRTOS C drivers on ESP32 for LM35 temperature, ACS712 current, PIR and LDR sensors; streamed data via MQTT/WebSocket to a React dashboard → https://github.com/alexhaya4/smart-streetlight-dashboard
  • AS5600 Encoder & Stepper: Debugged long-lead I²C noise on AS5600 with pull-ups, shielding, and timing tweaks; wrote modular C++/Arduino code for stepper control with encoder feedback
