Kostiantyn takes gadgets apart — and not just metaphorically. Over nine years working at a leading Ukrainian IT company he has tested and configured hundreds of devices — from budget smartphones to professional laptops and smart home systems.
He graduated from Odessa Polytechnic University, where he gained a deep understanding of how technology works from the inside. This gives him an edge over most reviewers: Kostiantyn doesn't just describe specs from a press release — he understands what's behind them and how they perform in real-world use.
At TechVisor.pro Kostiantyn runs the Gadgets section — objective reviews and device rankings for our readers. Smartphones, laptops, headphones, charging stations, smart home — he tests all of it from the perspective of practical value and real price-to-quality ratio. His core question when reviewing any gadget: is it worth the money for an everyday user?
