Maker / Embedded / Automation / Open Source

I build practical software and embedded systems that solve real operational problems.

My interests sit at the intersection of automation, infrastructure, IoT, AI, and security from internal dashboards and backend services to ESP32 devices, MQTT platforms, Linux infrastructure, and AI-powered developer tools.

I enjoy turning repetitive processes into reliable systems that are easier to operate, monitor, and maintain.
