Joined Oct 2026

I am a Senior C++ Software Engineer and Tech Lead with deep expertise in modern C++ (11/14/17/20) and high-performance, cross-platform development for macOS, Windows, and Linux. I specialize in real-time image and video processing, designing and optimizing performance-critical processing pipelines, GPU-accelerated compute (GPU shaders written in Slang), and computer-vision and ML-inference integration (OpenCV, OpenVINO). I have experience evolving cross-platform C++ core libraries, integrating native macOS frameworks (Objective-C++), and applying multithreading and memory-management techniques to maximize throughput. I am a strong architectural thinker who leads small feature teams from design to delivery, balancing quality, performance, and product impact across the full SDLC (SCRUM/Kanban, OOD/OOP, CI/CD, unit testing with gTest/GMock).

Lead the development of high-performance real-time audio/video processing modules in C++ (GStreamer, WebRTC), designing and optimizing pipelines and frame-level transformations for low-latency throughput. Profile and optimize hot paths using multithreading, memory-management tuning, and GPU-accelerated compute. Developed a custom GStreamer effect element with GPU shaders written in Slang to process and tune video thumbnails for recorded sessions. Architect cross-platform C++ solutions and Qt (QML) interfaces. Lead a team of 6 engineers, driving architectural decisions while remaining a primary hands-on contributor, and increased team delivery speed by more than 3× through stronger engineering processes, mentoring, and AI-assisted development workflows.

Developed and optimized C++ REST API endpoints and microservices; tuned SQL queries for faster data retrieval and lower service response times. Designed a custom high-performance Sitemap Generator with a background-job crawler that generates XML maps and uploads to AWS S3 on schedule or on demand, raising indexed dynamic-page coverage from about 60-70% to nearly 100% and eliminating manual maintenance.
