About Me

CTO at Intensa. 11 years in the industry, 5 of which in team and project management.

I define technology strategy, implement AI automation, and manage infrastructure and project security.

I combine management with hands-on engineering — designing architecture, writing code on complex tasks, participating in pre-sales. I also build my own products in monitoring, cybersecurity, and EdTech. I host developer meetups and have experience teaching web development.

Currently growing in cybersecurity, pursuing certifications. At the same time, integrating AI into development workflows — from code review to routine automation.
