About me

Who I am

Hi, I'm Nikita, a 17-year-old full stack AI-native developer. I'm currently studying at KPI at IASA, specialty 124 System Analysis, and building software alongside my studies.

I'm known for being responsible, kind, and dedicated, always striving to give my best in everything I do.

My Work Experience

A small selection of Top Projects

Featured

Interactive Maps City

A collaborative map platform for city utility teams to plan, draw, and maintain infrastructure on shared workspaces. Multiple editors can work on the same map at once — with live cursors, instant updates, role-based access, and a nested project structure for organizing work at scale. Built for heavy use: large maps, many objects, and reliable backups with preview and restore, plus an admin panel for users, activity, and system oversight.

After payment the coach grants access to a private Telegram group with a single Access button. A built-in AI assistant answers coaches' questions about how the panel works.
