A 13-year-old who made his own chess app

Hey everyone,
My name is Nikola. I am 13 years old and the current U14 Chess Champion of Serbia.
Preparing for championship tournaments taught me exactly what a player needs to win. But I got tired of big platforms locking deep analysis and opening tools behind expensive paywalls. I needed a limit-free app to practice my lines, so I decided to build my dream platform myself.
I took all my real tournament experience and transformed it into a free web application designed for competitive players.
I will let the features speak for themselves. Check out my custom tools and see the app for yourself: https://masterchess.live ♟️👑
