Senior Android Developer, OTT & video streaming specialist. I help video-first platforms ship scalable, stable native mobile and CTV apps: Media3/ExoPlayer, HLS/DASH delivery, multi-DRM (Widevine/PlayReady), server-side and client-side ad insertion (SSAI/CSAI), and QoE analytics.

6+ years, 10+ production apps across Android and Connected TV, 1M+ viewers. On a high-traffic MENA OTT platform I locked stability at >99% crash-free and cut cold-start by ~40%.

Here's the thing though: debugging a streaming issue the conventional way means Charles Proxy + adb logcat + manually fetching the manifest in a browser. All at the same time. On a tethered device. Each round takes 15–30 minutes. I got tired of that, so I started building tools to pull that whole workflow into the app itself, then shipped them to Maven Central and SPM.

Currently freelancing. Open to Android contract and senior full-time roles.

Kotlin Multiplatform debug SDK for Android and iOS. Manifests, per-segment metrics, CDN headers, ABR/track switches, and DRM lifecycle: all on-screen, no Charles Proxy, no tethered device, no production risk. One shared Kotlin core, a thin native adapter and overlay on each platform. On iOS 18+ it reads the AVMetric segment stream for true per-segment timing, at parity with the Media3 side.

iOS: add the package via Swift Package Manager, then import StreamProbe.

QoE analytics SDK for Media3. Crash logs tell you something broke. They don't tell you a user sat through an 8-second startup time. Media3Watch tracks startup duration, stall count, and buffer health, in Logcat or on a self-hosted Grafana dashboard (Ktor + PostgreSQL + Docker).

Shorts/Reels-style vertical video feed. Media3 + Jetpack Compose reference architecture for paged video playback.

Self-initiated Android TV app built with Jetpack Compose. R&D side project that shipped to production.

• StreamProbe: decode-capability visibility. Surfacing Tracks.Group.isTrackSupported() on VariantInfo, so a greyed-out rung can say "present but undecodable by this hardware" instead of looking the same as a config cap.
• StreamProbe: live TrackSelectionParameters. Showing why the selection pool was narrowed (max-size cap vs. max-bitrate cap vs. bandwidth fraction), not just that it was.
