As a forward-thinking Senior Engineer and Team Leader with over two decades of experience, I work as a full stack developer specializing in Video Streaming and real-time communication solutions based on WebRTC. I combine strong architecture thinking with hands-on delivery, acting both as a technical leader and a practical full stack web developer who understands real product needs and builds scalable WebRTC-powered systems. Today, my focus as a full stack developer includes the strategic application of advanced AI technologies alongside WebRTC-based real-time communication platforms. I actively work with OpenAI APIs, Whisper for speech recognition, LLaMA2 for open-source large language models, and LangChain for building AI-driven workflows. This positions me as a full stack developer AI who can integrate intelligence directly into real-world WebRTC video and streaming products. Throughout my career as a full stack developer, I’ve contributed to Telemedicine, Online Education, and Real-time Entertainment by building WebRTC-powered communication platforms. I’ve led teams delivering webinar platforms, live chat systems, and complex real-time applications, acting both as a senior web developer and system architect who ensures scalability, security, and long-term maintainability for WebRTC infrastructures. In AI-focused projects, I operate as a full stack developer who bridges data, logic, and user experience inside WebRTC-enabled applications. My team and I integrate conversational AI, speech-to-text, and knowledge-driven systems using OpenAI, Whisper, and LLaMA2. With LangChain, we design intelligent pipelines that automate workflows and data processing, enhancing WebRTC communication platforms with AI-driven capabilities. WebRTC remains a core part of my work as a full stack developer, especially for building high-performance real-time systems. We design everything from low-latency WebRTC infrastructure to complete applications, delivering solutions that work seamlessly across web and mobile. This includes building scalable video streaming app architectures capable of handling thousands of concurrent users through WebRTC. As a full stack developer, I also provide consulting and development services across North America and Europe, helping companies design and build WebRTC-based video communication platforms. I work with companies in Entertainment, E-Learning, Healthcare, and Finance. Depending on project needs, I act as a React developer, Wordpress developer, or mobile app developer while implementing scalable WebRTC solutions. Our services as a full stack developer team include system architecture, UI/UX design, and custom development of WebRTC streaming and real-time communication platforms. We build modern interfaces, robust back-ends, and real-time systems, including secure WebRTC video stream delivery for live and on-demand use cases. We have worked with most of the major Webinar and Online Education platforms on the market, delivering solutions as a full stack developer team that understands both the business and technical sides of WebRTC video streaming products. We frequently modernize existing platforms and migrate legacy systems to scalable cloud-based architectures built around WebRTC technologies. As a full stack developer, I’ve led the creation of webinar systems, live chat apps, WebRTC video conferencing platforms, real-time video auctions, messengers, e-learning platforms, telemedicine solutions, dating apps, Twitch-like platforms, TikTok-style apps, VoD systems, and live shopping platforms. Many of these solutions rely on modern stacks including full stack developer React and full stack Lavarel approaches integrated with WebRTC. Beyond development, I support clients as a full stack developer with load testing and performance optimization for large-scale WebRTC streaming systems. My background across front-end, back-end, databases, and cloud platforms allows me to lead projects end-to-end and deliver reliable, production-ready WebRTC platforms. I invite you to collaborate with me as a full stack developer who understands AI, WebRTC, and scalable real-time product development. Together, we can build innovative WebRTC-powered solutions that align with your business goals and grow with your users.

Expert-Vetted Top 1% on Upwork | Top 10 Machine Learning Agency on Upwork | 7+ Years in Production AI | Sports, Industrial, Satellite, Healthcare I'm a Computer Vision Engineer and Machine Learning Engineer with 7+ years delivering production-grade AI systems. Upwork has Expert-Vetted me as a Top 1% specialist in this niche, and our team is ranked among the Top 10 Machine Learning agencies on Upwork. I work with product teams and startups across sports analytics, industrial inspection, satellite and aerial imagery, access control, healthcare, and generative AI — any domain where visual data needs to become reliable, actionable output running in production. As a Computer Vision Engineer, my core work covers object detection, multi-object tracking, pose estimation, image segmentation, image processing, and real-time video analysis. I build end-to-end pipelines in Python using OpenCV, PyTorch, TensorFlow, and Keras, from dataset preparation and model training through TensorRT optimization and Docker deployment on cloud or NVIDIA Jetson edge hardware. I use C++ for performance-critical components where Python latency is a bottleneck. The domains where computer vision engineer experience creates the most value: sports analytics (player tracking, performance metrics, automated statistics from broadcast video), industrial inspection (defect detection and quality control on production lines), satellite and aerial imagery (object detection and segmentation for infrastructure analysis), access control and security (vehicle identification, multi-camera real-time monitoring), and healthcare and biomechanics (pose analysis, body measurement, and biomedical signal processing connected to AI coaching backends). As a Machine Learning Engineer and Data Scientist, I also build systems for structured and time-series data: demand forecasting, anomaly detection, biomedical signal analysis, and structural health monitoring. My data scientist workflow covers scikit-learn, pandas, NumPy, and SciPy alongside deep learning frameworks, with experiment tracking and evaluation metrics to ensure models perform consistently in production. When projects require generative AI or LLM components, I deliver RAG pipelines with LangChain and vector databases, synthetic dataset generation tools, and document processing systems using the Gemini API. Regardless of domain, the computer vision engineer approach stays the same: combine OpenCV-based preprocessing with deep learning inference into a scalable, testable pipeline that holds up under real-world conditions — variable lighting, occlusion, low resolution, multi-camera setups, and edge hardware constraints. I work with YOLO-family models, ByteTrack and DeepSORT for tracking, MediaPipe and MMPose for pose estimation, TensorRT and ONNX for inference optimization, and FastAPI with Docker for production deployment. I work with a specialized team that includes a computer vision PhD, deep learning researchers, and mathematical optimization specialists. This lets me scope complex systems, split parallel workstreams, and deliver a full Computer Vision Engineer engagement faster than a solo contributor could. Clients typically work with me when they need: - a Computer Vision Engineer to build detection, tracking, or segmentation systems from scratch - a Machine Learning Engineer to productionize a research model and meet latency requirements - a Data Scientist who can go from raw data to a deployable model end-to-end - an AI engineer to integrate LLM or generative components into an existing backend - real-time or edge inference optimized for NVIDIA Jetson or mobile deployment - a Python developer who understands both the AI pipeline and the surrounding system architecture If you need a Computer Vision Engineer with the full stack from dataset to deployed API, let's talk. Main stack: Python, OpenCV, PyTorch, TensorFlow, Keras, YOLO, ByteTrack, MediaPipe, MMPose, CoreML, TFLite, TensorRT, ONNX, scikit-learn, FastAPI, Docker, PostgreSQL, C++, NumPy, pandas, SciPy.
