I’m Yehor Yurkevycn.

I’m a DevOps Engineer specializing in building stable, fast, and scalable systems that let developers focus on writing great code instead of struggling with deployment and infrastructure.

My journey began in 2018 when I was part of a small team that constantly faced the same painful question: “It works on my machine, but not in production.” That moment made me realize I wanted to eliminate those problems before they even appeared. Over the past seven years I have built dozens of deployment pipelines, automated testing, releases, and monitoring for both Dart and C# projects.

One of my proudest achievements was fully automating releases for a high-load system handling over 800,000 requests per day. Release time dropped from 3 hours to 11 minutes, and critical incidents were reduced by 12 times. I also introduced Infrastructure as Code practices that are now the standard across every project I work on.

Before focusing purely on DevOps, I worked as a regular developer, then as a Team Lead, and for the last four years exclusively as a DevOps Engineer. I became the person everyone calls at 3 a.m. when something breaks in production.

Why did I create this course in December 2025?

Because after years of watching talented developers lose weeks or even months on manual deployment setups, I realized almost no one teaches developers how to deliver their code safely and reliably. I got tired of seeing great code die because of bad infrastructure. That’s why I decided to put everything I’ve learned into one course — so that anyone learning Dart and C# can immediately understand how real professional development works.

This course is not just another set of lessons. It contains exactly what I wish someone had shown me when I was starting out. My goal is simple: when you finish this course, you should feel confident that you know how things should actually work in real life.
