Projects
Ruby Sea - VS Code Theme
A custom VS Code dark theme I built for personal use and published to the Marketplace. Includes full editor and workbench theming with semantic highlighting and consistent UI colors. Actively used by thousands of developers.
Quirk Counter 🐉
A React event-tracking dashboard built to experiment with performance optimization. I implemented modular components, real-time search and filtering, drag-and-drop task management, and persistent client-side storage. The project focuses on frontend performance and UX, using lazy loading, code splitting, memoization, and debounced LocalStorage persistence, along with a responsive layout and full keyboard accessibility.

A personal portfolio built with Next.js and TypeScript to showcase my full-stack work across web, mobile, and backend projects. I designed the layout, implemented responsive UI, and added PWA functionality with offline support and service worker caching. Deployed on Vercel and optimized for performance and navigation.
