I created Tago, an RFID attendance system using an ESP32-S3, RC522 RFID reader, RFID cards, buzzer, blue LED and Wi-Fi. Students tap their cards, the ESP32 sends the UID to the backend, and the system identifies the student, checks their class/session, and records attendance through the web dashboard. The most challenging part was connecting the hardware, backend, database and frontend reliably, especially handling active sessions, duplicate scans, authentication and network issues. I’m most proud of turning a physical RFID scan into a complete working attendance workflow. To test it, users need a registered RFID card, active class session, configured reader, backend and database.

I built a custom 4-key macropad using a Seeed Studio XIAO RP2040. The project involved designing a PCB in KiCad, creating a 3D-printed case in Fusion 360, assembling and soldering the hardware, and programming it with QMK firmware. The most challenging part was learning PCB design and setting up the firmware correctly. I am proud of successfully completing the entire design-to-build process. To test the project, connect it via USB-C and use VIA to verify and customize the key mappings.
