React Router (Data

Pizza Delivery Co. React Router (Data API): Implemented the createBrowserRouter using Loaders and Actions. This shifts data fetching to the routing layer, eliminating fetch-on-render waterfalls and layout jank. Redux: Managed Global UI state and persistent data using Redux, ensuring a single source of truth and predictable state transitions. Clean Architecture: Combined the power of Router Loaders for initial data fetching with Redux for long-term state management, creating a seamless and snappy user experience.

Cover image for • Engineered an end-to-end Explainable

• Engineered an end-to-end Explainable AI (XAI) application for retinal scan classification utilizing transfer learning on a fine-tuned ResNet50 architecture. • Implemented Score-CAM techniques to generate visual heatmaps, ensuring AI diagnostic predictions were interpretable and transparent for medical use cases. • Developed a server using Python and Flask to serve machine learning inference, supported by a PostgreSQL database for reliable data management. • Built a responsive, type-safe user interface utilizing React, TypeScript, and React Query for highly efficient server-state management

Cover image for • Developed a feature-rich, data-intensive

• Developed a feature-rich, data-intensive Single Page Application (SPA) to solidify advanced React component architecture and modern state management techniques. • Engineered a highly responsive frontend by leveraging React Query to handle complex data fetching, caching, and synchronization, effectively separating server state from UI state. • Implemented advanced React patterns, including Higher-Order Components (HOCs) and Render Props, to build highly modular, reusable, and maintainable UI components. • Built a sophisticated user interface featuring dynamic table pagination, a fully functional dark mode toggle, and responsive layouts.

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.

Cover image for A production frontend case study

A production frontend case study focused on performance stability, predictable rendering, and controlled behavior as data volume and traffic grow. The work emphasizes understanding client-side caching, state lifecycles, and runtime costs to prevent gradual degradation in long-lived React and Next.js applications.

Cover image for Ulomira is a live production

Ulomira is a live production web platform where frontend architecture and long-term stability were treated as first-class concerns. The work focused on designing a predictable React / Next.js frontend that scales over time, with clear state boundaries, resilient structure, and maintainable patterns. Rather than optimizing for rapid feature delivery, the emphasis was on reliability, clarity, and frontend behavior that remains stable under real-world usage, ongoing changes, and evolving requirements.

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.
