Professional networking, unchained. NFC business cards linked to a sub-100ms web portal.

01. THE NATIVE NFC WRITER

Programming standard NFC tags requires deep Android system integration. I built a custom writing pipeline that format-locks generic NTAG213 chips, writes secure URL payloads conforming to the NDEF standard, and handles transaction state failures. Business professionals can tap their cards against the phone to program new networking links instantly.

02. SVELTEKIT COMPANION CARD

Digital business cards must be lighter and faster than standard websites because they are loaded under pressure. I built the card web app using SvelteKit adapted for static delivery. By compiling dynamically from Simple Icons, it eliminates heavy image asset loading, reducing page sizes to a mere 35KB with a sub-100ms time-to-interactive.

03. FIRESTORE REAL-TIME SYNC

Users modify their contact configurations on the fly. The Android client connects directly to Cloud Firestore. Upon editing links in the native console, the data is instantly synchronized with the companion card serverless routes. The target viewer page updates in real-time for anyone browsing the card, requiring zero manual refreshes.
