Engineered a browser-side per-pixel raster extraction engine, converting hover coordinates to Web Mercator tile XYZ, drawing COG tiles from TiTiler, and inverting colormap rescale to recover exact NDVI, NDMI, MSAVI, and NDRE values, supported by a 50-tile LRU cache and 30ms debounce.

Designed a 3-level RBAC permission tree with precomputed ancestor and descendant maps, ensuring granular access control that guides users to upgrade paths instead of silently hiding features.

Built a comprehensive regression testing platform utilizing Vitest across hooks and API clients, and a Playwright suite covering every route, capturing UI login as storage state and reporting DOM snapshots, network payloads, and video in HTML for robust quality assurance.

Developed a GDD chart in raw D3 with linear scales, monotone-curve generators, mean ±1σ confidence ribbon, and cumulative-sum derived series, animated via framer-motion path tweens, for advanced data visualization.

Built an OpenAI-powered pipeline that extracted, classified, and severity-ranked raw pentest findings, populating a custom HTML report template and generating PDFs via Puppeteer.

Synced security findings to Vanta and auto-triggered severity-based Jira tickets and Slack notifications, saving over 5 hours per report cycle and significantly streamlining vulnerability management.
