About the Author

Oleksandr is someone who doesn't just understand how technology works — he knows how to explain how to get the most out of it in real life. For over 12 years he has worked at a Ukrainian IT company, dealing with practical challenges every day — from configuring data protection to automating routine processes.

He graduated from Odessa Polytechnic University, where he built a solid engineering foundation and learned to think systematically. But Oleksandr's greatest asset isn't theory — it's practice: years of work on real IT projects have turned into an extensive collection of proven solutions that actually work.

At TechVisor.pro Oleksandr runs the Lifehacks section — the most practical part of the site. Here he writes about how to protect your data online, choose a reliable VPN, learn to code from scratch, earn money online, and use AI for real-world tasks. Every article isn't a retelling of someone else's experience — it's personally tested advice from someone who has spent over a decade in IT.
