Konstantin Beregovoy

About

More than 15 years in frontend and 20 in programming. I started by teaching programming and robotics, then moved into web development, fintech and cybersecurity products.

I care about the place where UX, architecture and business rules meet. I lead frontend teams, set engineering standards and bring AI into the workflow in a way a team can adopt and scale.

I contribute to web standards and open source, and I write about what I learn.
