This project builds a QR-code classroom attendance system with two parts: an Android app for instructors/students and a Java Spring Boot backend with MySQL. REST APIs handle login, CRUD, class join, session creation, check-in, stats, and report export, while WebSocket pushes real-time attendance updates for large classes. Scales for 100+ students!!

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.

Pushes, PRs, issues, reviews and comments — stars and forks excluded, so this is contribution rather than popularity

No issue or PR events — this repo's activity is pushes only.
Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 0 stars here means stars gained during the window, not the repo's star count.
