iOS Developer Freelance

VRT

Brussels, Belgium · Hybrid

Working on the VRT MAX iOS and tvOS apps. Joined right after VRT NU rebranded to VRT MAX and helped ship a brand new native iOS app. Extensively worked on the VRT Video Player, which originally wrapped THEOplayer and was migrated to a fully native AVPlayer implementation with Google IMA integration. The player is a modular API consumed by all VRT apps and bridged to Flutter for cross-platform use. Also responsible for writing a shared native media analytics framework used across many VRT touchpoints. Active member of the Mobile Chapter and DevOps Chapter.

MO ("Metaverse Organism"), a friendly AI companion: Tamagotchi meets Siri. A 3D creature you can talk to using Apple's Speech API, powered by GPT-3 with text-to-speech. The 3D game loop ran in React Three Fiber, communicating with native code over a custom JavaScript event bridge. Built and shipped a prototype in a couple of weeks, fast iteration speed. Early on there were Solana blockchain integrations connecting with the iOS Phantom Wallet app. Millions of views on TikTok and a vibrant Discord community.
