PROFESSIONAL PROFILE

Computer Vision and AI developer focused on building practical video analytics and model-training platforms. Hands-on experience with dataset preparation, annotation workflows, training and evaluating object-detection models, multi-object tracking, OCR pipelines, backend services, and user-facing CV tools. Currently building BVP (Bird's-Eye Vision Platform) for aerial and small-object detection, tracking, training, evaluation, and inference. Visual Odometry, SLAM, camera calibration, ONNX/TensorRT deployment, and edge inference are active learning and development areas rather than production-level specialization.

RELEVANT EXPERIENCE

Computer Vision & AI Platform Developer | Independent Product Development | 2024 - Present
• Building BVP (Bird's-Eye Vision Platform), a modular system for aerial and small-object detection, tracking, dataset management, model training, evaluation, checkpoint comparison, model inspection, and video inference.
• Developed Vehicle Traffic Platform for vehicle detection and tracking, license-plate OCR, vehicle color/make recognition, event search, watchlists, analytics, and configurable per-camera processing.
• Designed a multi-stage CV pipeline: frame-quality filtering -> detection -> tracking -> plate detection -> best-frame selection -> OCR -> format validation -> temporal voting.
• Built model-training workflows for dataset upload, annotation, frame extraction, train/validation/test splits, training jobs, metric monitoring, validation, model registration, and checkpoint/model management.
• Working on model export, ONNX/TensorRT integration, edge inference, hardware profiling, and inference optimization as active BVP development tasks.
AI Automation & Full-Stack MVP Developer | Independent / Portfolio Projects | 2024 - Present
• Built AI applications, assistants, dashboards, bots, data-processing workflows, and API integrations using Python, FastAPI, Next.js, TypeScript, PostgreSQL/Supabase, and LLM APIs.
• Use Codex, ChatGPT, Claude, and Gemini for AI-assisted engineering while manually reviewing architecture, testing edge cases, validating generated code, and documenting implementation decisions.
Video Editor / AI Content Creator | Freelance | 2022 - 2024
• Professional background in video processing, frame quality, encoding, composition, and visual consistency before transitioning into AI and Computer Vision development.
CURRENT COMPUTER VISION DEVELOPMENT

Learning and prototyping:
• Camera calibration fundamentals, lens distortion, reprojection, feature matching, optical flow, and camera pose estimation.
• Early-stage Visual Odometry, VIO, SLAM, IMU sensor-fusion, and GPS-denied navigation concepts for UAV and mobile robotics.
• ONNX/TensorRT conversion, edge inference, inference optimization, and hardware-aware model deployment within BVP.
