My Role
- Sole creator across the full stack — firmware, backend, and frontend.
- Arduino/ESP8266 firmware for the RFID reader/writer used for office attendance.
- Backend: Manages encryption-secret rotation and webhook signature verification so attendance webhooks can’t be spoofed.
- Frontend: React dashboard for viewing attendance data.
This is Koders’ internal office attendance tool, distinct from the separate RFID system built for the Indian Army.
