About Konstantin

I have a BSc in Applied Mathematics & Computer Science and 10+ years of experience in tech — as a software developer, then product manager, now building my own startup.

I've worked on backend systems for apps with 100M+ users, built and shipped my own software products, and spent years solving real engineering problems — not just academic exercises.

In university, I tutored programming and helped teach contest and olympiad math. I've also given lectures on software basics to adults. I genuinely enjoy the moment when something clicks for someone.

I got into programming through math — I loved algorithms and problem-solving before I ever wrote code. That foundation still shapes how I think and teach: understand the logic first, syntax second.

About the lesson

My approach is simple: I help you actually understand the code, not just get through the assignment.

If you're stuck, I want to figure out why — is the concept too abstract? Are we missing a building block? I'll bring it down to earth with examples and analogies until it clicks.

Lessons can go different ways: you bring something specific (assignment, leetcode problem, concept you don't get) and we dig into it — or we work on filling gaps, building foundations, or learning something new together. Either way, I explain the "why" behind things, not just the "how."

I'm a good fit if you're: a university or college student struggling with CS courses, learning to code on your own, prepping for technical interviews, or want to get better at algorithmic thinking and problem-solving.

Languages: Python, Java, JavaScript, SQL.
Topics: algorithms, data structures, leetcode-style problems, debugging, general programming logic.
