Community

NTU NEST

At NTU NEST, a student startup community, I help founders, builders and investors find each other.

I build the tools a room needs. Roomwho started as NEST Night’s guest list.

Skitwright

Animated shorts from a script

An engine that turns a dialogue script into a finished vertical reel: voices, lip sync, camera, music, mix.

  • Deterministic: frame i always renders the same.
  • Automated QC for framing, clipping and loudness.

Roomwho

Who’s in the room?

A live attendee directory, built for NEST Night. Scan a QR code, make a card, see who’s here. Live three days after the first commit.

  • Give to get: no card, no names.
  • Per-event data, hashed emails.
