Challenge
Implementing a secure authentication system with role-based access control for customers, admins, and vendors was complex. Managing session persistence across server-side rendered pages while ensuring CSRF protection required careful architecture.
Solution
I used NextAuth.js with JWT strategy for stateless authentication, combined with middleware-based route protection. For role-based access, I created a custom middleware that checks user roles before rendering protected pages, and implemented CSRF tokens on all mutation endpoints.
Challenge
Optimizing the product listing page for 1,000+ concurrent users with real-time inventory updates caused significant database load and slow page loads.
Solution
I implemented TanStack Query for client-side caching with stale-while-revalidate strategy, added server-side pagination, and used Nginx reverse proxy caching for static assets. This reduced database queries by 60% and improved Lighthouse performance score from 45 to 92.
Challenge
Building a responsive admin dashboard with real-time order management, inventory tracking, and analytics charts that worked seamlessly across devices.
Solution
I designed a modular component architecture with Redux Toolkit for global state management. Charts were built with server-side data aggregation to minimize client-side processing, and the dashboard layout uses CSS Grid with Tailwind responsive breakpoints for full mobile compatibility.
