Tech Stack & Libraries
Engineering Challenges & Solutions
Real-Time AI Candidate Matching & State Synchronization
Synchronizing high-frequency streaming AI match updates across multi-tenant recruiter dashboards without triggering layout shifts or dropping render frames.
Implemented optimistic UI updates powered by Zustand state slicing and WebSocket subscriptions. Offloaded heavy candidate scoring computations to dedicated Web Workers to ensure a locked 60fps main thread.
Permission-Aware Dynamic Layout Engine
Rendering complex RBAC data restrictions and customizable widget views for multi-tier hiring teams without duplicating UI components or degrading bundle size.
Engineered a dynamic higher-order layout resolution engine using Next.js Server Components. Restricted data attributes are safely stripped at the server boundary before payload transport.
High-Density Candidate Pipeline Kanban Board
Managing drag-and-drop interactions across thousands of candidate cards with smooth 60fps animation during concurrent live updates.
Built a virtualized Kanban architecture with HTML5 drag-and-drop combined with GPU-accelerated CSS transforms and debounced position state persistence.
