Real products, internal systems and experiments I've helped bring to life.

Software Developer @ 89FM

2026 — Present

I build production software for a major radio station — from public-facing products to internal platforms, automation systems and mobile experiences.

  • Developed campaign websites and digital experiences designed for high-traffic moments during live radio promotions.
  • Built an internal asset management system using RFID technology to track production equipment like cameras, lenses and accessories.
  • Developing the official radio app, bringing live streaming from multiple stations into a modern mobile experience.
  • Built Xablaw, a mobile-first entertainment platform focused on movie discovery, personalized recommendations and a swipe-based experience.
  • Created automation tools and AI-powered experiences that process user interactions and connect online campaigns with real-world events.
  • Built a background daemon that keeps the radio's "Now Playing" data synchronized in real time, automatically updating what is currently on air.
  • Built an internal monitoring and notification system for CI, self-hosted runners and production VPSs, detecting failed containers, unexpected services and infrastructure issues.
  • I designed and developed a game hub for the GC2 group, featuring various game templates that enable promotions with games to be easily created and managed by any team member, regardless of programming knowledge.
