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.
Built production-grade encoders/decoders for JPEG 2000 and HTJ2K — broadcast, medical imaging, and digital cinema. GPU-accelerated via Metal, OpenCL, CUDA & Vulkan, hitting Full HD @ 60 FPS, 4K @ 30 FPS and 85% energy reduction. Deep codec & GPU expertise I bring to new problems.
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.
