I got into embedded systems in 2017. Not through a structured course or a bootcamp — through curiosity, a cheap development board, and a lot of time spent reading datasheets that assumed you already knew everything.

The early years were the hard way. Most tutorials stopped at blinking an LED. If you wanted to understand how to build firmware that actually survived in the field — reconnecting after a network drop, handling sensor failures gracefully, running multiple tasks without everything stepping on each other — you were mostly on your own. Forums, source code, trial and error.

Eight years later I still love this work. ESP32, FreeRTOS, Modbus, MQTT, industrial IoT — the kind of firmware that runs in factories and field devices, not just hobby projects on someone's desk. That's where the interesting problems are.

I started LogicFrenzy because the resource I needed in 2017 still doesn't really exist. There are beginner tutorials everywhere. There are Espressif API docs. There's almost nothing in between — practical, production-focused content that treats you like a developer, not a student. That's what this site is trying to be.
