About me

I am an engineer and Full-Stack IoT Developer. I design hardware and write software, handling projects comprehensively from PCB schematics to final web or mobile applications. I take full responsibility for bridging these two worlds.

My core expertise covers:

• Hardware (PCB Design): Designing multilayer boards (EasyEDA/KiCad) with production files for JLCPCB. I specialize in ESP32/ESP8266, advanced LED control, sensors (I2C/I2S), and stable power architecture.
• Firmware: Writing reliable code for microcontrollers (C++, MicroPython), focusing on memory optimization and network communication.
• Web, Mobile & Automation: Creating web/mobile apps and interactive frontends. I integrate hardware with the cloud (IoT) and automate processes using Python.

I deliver complete solutions - from PCB tracks to code repositories. Have an idea for a device, an app, or a prototype that needs fixing? Let's talk.
