⚡ What I Do

🚀 GPU & Performance Engineering

I specialize in squeezing maximum performance out of Apple Silicon using Metal 4, NEON SIMD, and custom compute pipelines. My work spans video codecs, image processing, and real-time GPU monitoring — often achieving 5-10× speedups over industry-standard tools.

🎬 Multimedia & Codecs

Building production-grade encoders/decoders for JPEG 2000 and HTJ2K — targeting broadcast, medical imaging, and digital cinema. GPU-accelerated via Metal, OpenCL, CUDA & Vulkan with real-world results: Full HD @ 60 FPS, 4K @ 30 FPS, 85% energy reduction.

🔌 Developer Tools Ecosystem

Creator of 35+ JetBrains IDE plugins spanning security, architecture, DevOps, and productivity — plus extensions for VS Code and Safari. Highlights include GPU-accelerated SAST scanning (50-100× faster), Metal shader support, Kubernetes safety guards, and architecture decision tracking.
