I help companies design, train, and deploy computer vision systems that solve real-world problems — not just research demos. I specialize in end-to-end computer vision solutions, taking ownership of everything from data and model performance to system reliability and deployment. What I help clients build Real-time computer vision systems (detection, tracking, segmentation) Custom deep learning models (CNNs, Transformers, U-Net variants) Medical image analysis (retinal imaging, segmentation, diagnostics support) Agricultural computer vision (crop analysis, monitoring, automation) Industrial & inspection systems (quality control, defect detection) Training pipelines & ML automation (data processing, reproducibility, CI-ready workflows) Why clients hire me 5+ years of software engineering experience, plus deep specialization in Computer Vision & ML Applied CV experience across multiple industries (medical, agriculture, industrial, AR research) Master’s degree in Computer Vision, thesis focused on retinal choroid segmentation Strong focus on production-quality code, documentation, and maintainability Comfortable working beyond the model: APIs, pipelines, backend integration, deployment Tech stack ML & CV: Python, PyTorch, TensorFlow, OpenCV Vision tasks: Detection, segmentation, tracking, image processing and analysis, stereo calibration Backend: Python, FastAPI, Java, Spring Boot, C# Frontend & tools: TypeScript, JavaScript, Qt Data: PostgreSQL, MySQL DevOps & MLOps: Docker, CI/CD Testing: Automated & end-to-end testing (WebdriverIO) How I work I don’t just deliver a model — I deliver a working system.

Tasks, approaches and even tools, they are always different and developing, so I rarely see the point in remembering something very specific - such as api framework or even language details. When a task is focused and repeated, I make different snippets/helper configs/cheat sheets for increasing speed and orientation. And even if I wanted to forget about something I repeat 100 times a day, I could not. When the project turns up, I unload it from my memory and upload there new data from a new area. I have a little hard-drive, if you catch my drift, but very effective RAM. These qualities help me look at the problem afresh; to check, find and implement the latest technologies and solutions for my projects. Taking into account software development dynamics, this approach seems quite logical. I know and use a lot of things, I realize I can't know everything, and I am open to wide range of proposals, especially for positions with career and personal growth. Multitasking is my strong side, though I also can perform agile and specialized tasks almost like a focused developer. But I easily compensate it with process automation, goal-orienting, perseverance and working from home where I have all the conditions I need and all the time available except sleep. I might have liked to be a narrower specialist, but the clients can't be chosen - they should be provided with a service. ps: I have 3 years + of work experience with Azure services
