Things I build for fun

Personal projects outside of work — an end-to-end encrypted messenger, a hydration app and a mobile game I designed and built on my own.

Nuven

Private messenger, no phone number

An end-to-end encrypted messenger where your account is just a random 16-digit number: no phone number, email or name. Messages are encrypted on the device with an X3DH + Double Ratchet design and sealed sender, and the server is a zero-knowledge relay that keeps no logs. Native SwiftUI on iPhone and iPad, plus a web client.

  • End-to-end encrypted chats, photos, voice messages and groups
  • Sealed sender: the server never learns who sent a message
  • Encrypted voice and video calls over a relay, so IPs stay hidden
  • Edit, delete for everyone, read receipts and multi-device sync

  • 8 worlds, 13 obstacle types and AI rivals with personalities that predict hazards
  • Custom HLSL toon/outline shaders, ragdoll tumbles and haptic feedback
