Francisco Salgueiro

Francisco Salgueiro is an independent developer whose open-source work focuses on tools that re-imagine classic board-game software for contemporary players. His single published title, En-Croissant, is a cross-platform chess database written in Rust and TypeScript that combines the archival depth of traditional chess archives with the responsiveness expected of modern desktop applications. Typical use cases span from grandmaster preparation—where seconds need lightning-fast searches through millions of games—to club coaches who build repertoires for students, and to casual enthusiasts who simply want a distraction-free board to play and automatically annotate blunders. The program imports PGN, JSON and FEN sources, performs instant position queries powered by a local embedded engine, and exports interactive HTML reports for sharing novelties on forums or in classrooms. Because the code is MIT-licensed, advanced users also treat it as a sandbox: they fork it to add cloud sync, novel visualization layers or bespoke engine farms. En-Croissant therefore sits at the intersection of database, trainer and study hub, demonstrating how a lone developer can deliver professional-grade chess tooling without subscription walls. The application is available free of charge on get.nero.com, where downloads are routed through trusted Windows package sources such as winget, always pull the newest release, and can be queued alongside other programs for unattended batch installation.
