Side projects
Chess tools, analytics tooling, and the CI that builds them — API and database included.
Chess fundamentals for amateur players
Strategy, pawn structures, middlegame and endgame, in English, Russian and Chinese. Every claim cites the classic text it comes from, and the positions play inside the article.
A dataLayer inspector for Chrome
A side panel that logs every push as it happens, including the ones that fired before it was opened. Search, expand and copy any payload; nothing leaves the browser.
Filter-based search over six million chess puzzles
Lichess publishes the puzzles but no way to query them. This filters by theme, rating, popularity and length, over a DuckDB file that packs 72 themes into one bitmask column.
A Vue 3 adapter for Lichess’s PGN viewer
Wraps the viewer as a component with its config, props and API typed, so an editor completes them instead of the docs. Listed as the Vue wrapper in the official README.
A chess diagram web component
Renders a position from plain text through a chess font, so a diagram can take on any typeface — including chess fonts from the 90s. Zero dependencies, around 5 kB.
Shared CI and deploy workflows
Format, types, lint and test on one workflow, a static build to GitHub Pages on the other. Every repository on this page calls them instead of keeping its own copy.
