The digital workspace of Serhii Hrekov

Providing Software Engineering content, creating apps.

This blog is a living collection of my engineering notes - refined through real work and side projects.
Each post is written to be practical, honest, and reusable - like a developer's guide, not a diary. I hope these notes help you learn, debug, or build something better.

These are the apps, bots, and tools I've created - each one documented like a case study.
I break down what I built, how I built it, and why - sometimes down to the last line of code. Every project is both a product and a learning resource, shared openly for builders like me.
