Hi! I'm a Senior Software Engineer with 20+ years of experience in web, mobile and cross-platform solutions. I have worked as a Team Lead, CTO and Solution Architect on complex and high-load projects in e-commerce, fintech, healthcare, government, entertainment and sports tech. Today my main focus is AI and computer vision for sport: player and ball tracking, pose estimation, physical and tactical metrics from regular match video — football, futsal, tennis, squash, volleyball and more. I also build the whole product around the models: backend, dashboards and mobile apps. My key skills: - AI / Computer Vision (OpenCV, YOLO, object tracking, pose estimation) - Python (Django / Flask / FastAPI) - Front-end (Vue.js, React.js) - Cross-platform (Flutter / React Native / Electron) - Relational DBs (Postgres / MySQL) - NoSQL (MongoDB, Cassandra) - Big Data (Hadoop, Kafka, Sphinx) - DevOps & Cloud (AWS, Google Cloud, DigitalOcean) Feel free to contact me to discuss your project or check my current availability!
