Cover image for • Engineered a containerized (Docker)
• Engineered a containerized (Docker) Next.js/Node.js media showcasing application enforcing strict single-session-per-device authentication using JWTs and a Redis cache. • Resolved complex client-side race conditions during rapid user interactions by implementing a custom mutex lock for predictable state updates and seamless Optimistic UI rendering. • Engineered thread-safe, idempotent API routes to eliminate backend check-then-act race conditions, utilizing atomic Mongoose operators ($addToSet, $pull) to maintain strict database integrity under high-frequency traffic. • Streamlined backend data fetching and API response times by aggressively leveraging Mongoose's .lean() function to strip instantiation overhead from MongoDB documents. Plus, using atomic operations to prevent database inconsistency.

Taking Next.js to the Edge: Deploying "The Wild Oasis" on Cloudflare  A booking application built with Next.js 15, and deployed entirely on Cloudflare Pages. Moving away from traditional Node.js environments to the Cloudflare Edge presented some fascinating architectural challenges that pushed my engineering skills to the next level:  Edge Runtime Optimization: Leveraging nodejs_compat to run heavy server-side logic on V8 isolates for near-zero latency.  Advanced UX: Implementing useTransition hook along an optimistic update to make an instant, fluid user experience.

The-State (a dashboard for a class of my university) I built The-State specifically for students (my colleagues) to access lecture PDFs and take related quizzes, all in one convenient platform. On the admin side, the dashboard allows full control over the class: tracking student numbers and names, managing file uploads, blocking or controlling access, and monitoring Firebase storage and quota limits. The goal was to make the learning process smoother for my class while giving me an easy way to manage everything efficiently.
