❀️ Beyond Work - Personal Interests

🧠 Neuropsychology

I study neuropsychology to understand human behavior and brain working principles. This knowledge helped me found Wisepace, inspired by Andrey Kurpatov's works on neuropsychology and business development.

πŸš— Automotive

As a car enthusiast, I maintain and repair my vehicles independently. This hands-on approach not only saves money but also satisfies my passion for automotive engineering.

🌐 Web3

I'm passionate about Web3 and actively invest in cryptocurrency. Despite current corporate dominance in Web2, I believe Web3 will significantly impact the future of internet technology.
