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 Top Rated Plus · 100% Job Success · 19+ projects Based in Bangalore · Working with clients globally

I help companies build interactive solutions that improve training, safety, and product experiences. Over the years, I have delivered 70+ projects across AR/VR training, web-based simulations, and 3D configuration systems for startups, enterprises, and government-level organizations, primarily across Europe and international markets. My core focus areas: • Safety, onboarding, and SOP training modules • 3D product configurators and interactive visualization tools • AR and VR training simulations for enterprise teams • Web-based 3D simulations that run directly in the browser • Realistic digital walkthroughs using Gaussian splat environments I co-founded Gamebole, an immersive technology studio specializing in scalable AR/VR and web-based simulation systems. We work with a structured team of developers and 3D specialists to deliver performance-optimized solutions built for real business use. Companies typically work with us to: • Reduce training time and operational costs • Improve safety awareness through simulation • Replace physical training setups with scalable digital systems • Build high-performance 3D configurators for products • Develop web-first immersive systems without complex installs Technologies we commonly use: PlayCanvas, Unity, Three.js, WebXR, SUPERSPLAT, and custom backend integrations when required. If you are planning to use AR/VR or web-based simulations to improve training or product engagement, I would be happy to discuss your requirements.

I focus on building reliable software and solving difficult technical problems efficiently. I specialize in building and stabilizing VPN applications for iOS and macOS using Swift — and in hybrid stacks where a Go networking core powers the packet tunnel (gomobile, DNS interception, UDP/TCP relay) alongside Network Extension on the Apple side. My work focuses on the parts that are hardest to get right: NetworkExtension integration, tunnel lifecycle, lock/sleep recovery, kill switch and on-demand behavior, reconnect flows, and platform-specific networking edge cases under iOS memory and background limits. I also work with Xray and Libbox integrations and have hands-on experience with VPN technologies including OpenVPN, IKEv2, IPSec, WireGuard, VLESS, VMess, and Shadowsocks. Recent delivery: stabilized a production parental-control VPN app — domain and image filtering, MITM inspection, DNS hardening (including DoH fallback), and fixed intermittent "no internet while VPN is on" after extended device lock. Shipped stable TestFlight builds with production-ready, root-cause fixes. I help teams resolve difficult issues around race conditions, state management, reconnect behavior, and long-running reliability across Apple platforms (iOS, macOS, tvOS). I'm a strong fit for projects that need more than basic mobile development — especially apps where connection stability, traffic filtering, native platform behavior, and deep debugging are critical. What I can help with: • iOS and macOS VPN development (NetworkExtension, Packet Tunnel) • Swift + Go hybrid VPN cores (tunnel, DNS, stability) • Kill switch, on-demand, reconnect, and tunnel management • Parental control / content filtering (domains, HTTPS image inspection) • Debugging lifecycle, networking, and memory-pressure issues • Stability, performance, and production hardening I focus on production-grade reliability — stable tunnels, correct filtering under edge cases, and fixes that hold up in real-world use (lock/sleep, reconnects, memory limits), not temporary workarounds.

Senior C++ Audio & DSP Engineer | JUCE, VST3, AU, AAX – Low-Latency Audio Plugins & Real-Time Streaming Need a VST3/AU/AAX plugin that never drops a sample, a WebRTC streaming pipeline with perfectly synced audio, or a cross-platform desktop app with a hardware-accelerated UI? I build production-grade audio and video infrastructure that works reliably under the heaviest loads. I write high-performance C++ and Rust media engines that keep your audio buffers tight, your streams latency-free, and your UI fluid even during heavy AI inference. I bind optimized native backends to Electron, Tauri, React, or Swift/Kotlin frontends, delivering mobile and desktop products that feel snappy and professional. --- MY CORE EXPERTISE --- 🎛️ Audio Plugins & DSP (C++/JUCE) • VST3, AU, AAX plugins and standalone apps – cross-platform from day one. • Custom DSP: parametric EQ, dynamics, filters, spatial audio, AI-driven onset detection. • Multi-threaded audio buffer management, real-time safe processing, Web Audio API bridges. 🎥 Video Streaming & Broadcast (OBS, WebRTC, FFmpeg) • Custom OBS Studio plugins, WebSocket automation, live production tools. • Low-latency pipelines: WebRTC, HLS, RTMP, MPEG-DASH, frame-accurate A/V sync. • GPU-accelerated FFmpeg transcoding, stream packaging, VMAF quality analysis. 📱 Mobile & Cross-Platform Engines (C++/Rust) • Shared C++/Rust audio/video cores with native Swift (iOS) and Kotlin (Android) UIs. • Real-time, low-latency mobile audio processing and WebRTC integration. • Scalable architecture that reuses your engine logic across desktop, mobile, and web. --- FEATURED WORK --- 🚀 Render Studio – AI Music Production Suite I architected a cross-platform desktop app (C++/JUCE) featuring real-time AI voice cloning, stem separation, noise removal, and key/BPM analysis. Offloaded heavy AI inference to dedicated worker threads, keeping the hardware-accelerated UI completely smooth and responsive under full rendering load. 🎬 Live Broadcast Automation – OBS Plugin & WebSocket Controller Built a custom OBS Studio plugin and remote WebSocket control panel that automated scene switching, overlay triggers, and stream health monitoring for a 24/7 live channel. Cut manual operator workload by over 90% and eliminated on-air glitches with frame-accurate transitions. --- LET’S TALK --- I’m happy to offer a brief technical sanity check on your project’s architecture before you hire.
