I build embedded systems, write firmware, and love turning hardware ideas into reliable, real-world products.
My work revolves around ESP32, PIC, STM32/STM8, Renesas MCUs, FreeRTOS, Smart meter firmware, and communication stacks like Modbus, CAN, UART, I²C, and SPI.

I enjoy solving tough debugging problems, designing clean embedded architectures, and building tools that make firmware development smoother.

• Thrust Stand Data Logger — ESP32 system measuring voltage, current, RPM, thrust & temperature
• Path Recording Robot — Records manual motion & replays path autonomously
• Custom Modbus RTU Slave (ESP32 + FreeRTOS) — Supports all standard function codes
• STS Token Processing — Token parsing, credit updates, tamper integration, prepaid logic
• Seven-Segment Display Library — Character rendering, multiplexing, FreeRTOS task handling
• ADS1115 Sensor Drivers — Clean & robust analog measurement interface
