Senior iOS Engineer & founder of Dro1d Labs. Building privacy-focused, on-device tools for Apple platforms since 2010.

Core Focus

  • Nu11VLT: Zero-knowledge vault for secure media and encrypted notes.
  • NuDefndr: On-device media scanning for explicit content.
  • Defndr: Machine learning-driven SMS filtering and spam protection.
  • Interactive Media: "App-Books" (NullKit) bridging software and content experiences.

Timeline

  • 2025–Present: Expansion into interactive media, gaming, and publishing.
  • 2020–2024: Shipped Defndr (ML SMS filtering) and NuDefndr (media scanning).
  • 2014–2019: Android system modding, root-level privacy toolkits, low-level security experiments.
  • 2011–2013: Early App Store apps: Fact File (App ID: 406480795) and several viral soundboards.
  • 2010: Started iOS engineering (Objective-C).
