Senior C++ Audio & DSP Engineer | JUCE, VST3, AU, AAX โ 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 ---
๐๏ธ Audio Plugins & DSP (C++/JUCE)
โข VST3, AU, AAX plugins and standalone apps โ cross-platform from day one.
โข Custom DSP: parametric EQ, dynamics, filters, spatial audio, AI-driven onset detection.
โข Multi-threaded audio buffer management, real-time safe processing, Web Audio API bridges.
๐ฅ Video Streaming & Broadcast (OBS, WebRTC, FFmpeg)
โข Custom OBS Studio plugins, WebSocket automation, live production tools.
โข Low-latency pipelines: WebRTC, HLS, RTMP, MPEG-DASH, frame-accurate A/V sync.
โข GPU-accelerated FFmpeg transcoding, stream packaging, VMAF quality analysis.
๐ฑ Mobile & Cross-Platform Engines (C++/Rust)
โข Shared C++/Rust audio/video cores with native Swift (iOS) and Kotlin (Android) UIs.
โข Real-time, low-latency mobile audio processing and WebRTC integration.
โข Scalable architecture that reuses your engine logic across desktop, mobile, and web.
--- FEATURED WORK ---
๐ Render Studio โ 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.
๐ฌ Live Broadcast Automation โ 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.
