I build interactive experiences that run live in the real world — AI-powered kiosks, touchscreen displays, event games driven by physical buttons and Arduino sensors, Kinect installations, and VR for brand activations and exhibits. My focus: builds that run all day, unattended, in public, without crashing. 🟢 Most Unity developers can ship a build. Far fewer can make that build survive a live deployment — a sensor that drops mid-session, a visitor who yanks a controller, an eight-hour day with hundreds of hands, a machine that has to recover on its own when the power blips. That reliability layer is where I work. People think this kind of development is judged by art and interface. That's only one layer ❌ — I treat a project as layers, with high attention to detail, and I don't call it done until the small things are right: feedback, sound, edge cases, and the failure modes that only show up on the floor. 💎 What I build Touchscreen kiosks & interactive displays — multitouch, wayfinding, check-in, and museum/exhibit experiences built to run unattended AI-powered experiences — virtual reception assistants (speech + LLM), and a generative-AI caricature kiosk that captures a photo and prints a custom portrait, built by integrating AI APIs into real-time Unity apps VR experiences for activations, exhibits, and demos (HTC Vive / Vive Tracker, Meta Quest) Event & arcade-style games with custom physical controls — arcade buttons and switches talking to Unity over Arduino serial communication Sensor-driven & motion-controlled installations — Microsoft Kinect, Leap Motion, and custom Arduino sensor rigs PC games & interactive applications — standalone Windows builds, simulations, and real-time tools Mobile games for iOS & Android, plus WebGL browser builds 🧠 Core expertise Unity 3D / C# — gameplay systems, physics-based mechanics, real-time interaction design AI integration — connecting LLMs, speech, computer vision, and generative-image APIs into live interactive products, with fallback handling for unattended use Hardware & physical computing — Arduino serial communication, Kinect / Leap Motion tracking, custom controllers and sensors Cross-platform delivery — PC (Windows), mobile (iOS / Android), WebGL, and VR headsets Performance optimization across low-end and high-end hardware Modular, well-commented architecture any developer can pick up and extend 🛠 How I work Daily updates, video calls, and recorded walkthroughs — you'll always know exactly where your project stands, time zones aside. I battle-test every build under real conditions: Does it survive a full unattended day? Does it recover from a disconnected device — or a dropped API call? Does the interaction feel right the hundredth time, not just the first? Is the code clean enough for the next developer to follow? Behind all of it: 7+ years in Unity, including shipped titles with 5M+ downloads — so whether it's an AI kiosk, an installation, or a mobile game, the engineering underneath is production-grade, not a demo that works once. Tell me about your project — kiosk, installation, AI experience, or game — and let's figure out how to make it real. Thank you!

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.
