•Engineered an SVG-based tactical board editor with drag-and-drop player/ball placement, freehand drawing, curved/dotted/dashed arrows, undo/redo (30-level history stack), zoom/pan, and multi-scene management for creating complex tactical sequences
•Built a video analysis editor with time-based event tagging across 4 category groups (Common, Attacking, Defensive, Transition events), client-side clip extraction via FFmpeg WASM, and linking tactical boards to specific video timestamps
•Designed a custom shadcn/ui component system with 42+ primitives, CSS-based dark/light mode via next-themes, and configurable theme presets with HSL adjustments
•Implemented a full authentication system (login, signup, OTP, email verification, password reset) with JWT in httpOnly cookies, Zod validation, and middleware-based route protection
•Integrated an AI chat assistant (OpenAI/Gemini) with conversation management, persistent history, and board-context-aware analysis panels
•Created a cinematic landing page intro using GSAP with orchestrated animations and Lenis smooth scrolling
