Backend for a living: 1C-Bitrix and Bitrix24, PHP, MySQL, fourteen years of it. Moscow. The rest of my time goes to a game and to other people's codebases.

Browser MMORPG. Phaser on the client, an authoritative NestJS server on the other side, TypeScript across npm workspaces. Authoritative means the server owns the world state and the client only asks: no trusting the browser about where you are or what you hit. That constraint is most of the interesting work, and it is why realtime PvP is the part I care about getting right.

I contribute bug fixes and API documentation corrections to other people's projects. The bugs range from infinite recursion and broken Windows paths to object comparisons that throw on valid input and layer-name handling that silently skips work. Sometimes the mismatch is between a comment and a signature; sometimes it is between what the code is meant to do and what it actually does.

I use language-specific checkers to find suspicious patterns, then inspect each finding in context: the surrounding code, callers, and history. A checker result is a lead, not proof. For behavior changes, I reproduce the failure and add regression tests where practical, checking that they fail before the fix and pass after it. False positives go into a separate record so the tools can improve. The aim is a small, useful patch that a maintainer can verify.
