Full Stack Developer, Video Analytics Web ApplicationBuilt a video analytics solution for structural inspection of petrochemical tanks, reducing downtime from 2 weeks to 2 days and saving up to $100,000 in operational costs per tank. The solution features an end-to-end pipeline that processes drone footage to detect, locate, and classify structural defects, visualizing the findings spatially within a full-stack web application.To further enhance user efficiency, I built an image segmentation annotator for dataset refinement and a custom rich-text editor with a templating engine to automate reporting workflows.
