I build, debug, and fix production Roku streaming apps — including playback issues, ad failures (RAF/VMAP), and Channel Store certification problems.
15+ years shipping real Roku channels used at scale (Foxtel, ABS-CBN, MwareTV). Roku-only specialist — not a generalist experimenting with BrightScript.
I’m often brought in to fix apps that are already live but failing — playback issues, ads not working, crashes, or repeated certification rejections.
What I deliver:
- End-to-end Roku channels (BrightScript + SceneGraph, content feeds, deep linking, voice support)
- Debugging and fixing existing apps (crashes, render thread issues, legacy BrightScript problems)
- Streaming stability (HLS/DASH, DRM, adaptive bitrate, buffering fixes)
- Monetization that works (RAF, VMAP, SSAI, Roku Pay, AVOD/SVOD/TVOD)
- Channel Store approval (compliance, edge cases, first-pass approvals)
Common issues I solve:
- Playback failures (HLS/DASH, DRM errors, buffering)
- Ads not working correctly (RAF/VMAP/SSAI issues)
- App crashes and performance issues
- Channel Store certification failures
- Debugging legacy or poorly written BrightScript code
Delivered production channels for:
- Foxtel Australia — Kayo Sports, Binge, Flash
- ABS-CBN Philippines — iWant
- MwareTV Netherlands — IPTV platform
- Accedo USA — CenturyLink Prism, EPIX, AccuWeather
