I’m a Full Stack Developer with a strong Computer Science foundation in Java and Object-Oriented Programming. I enjoy building products that are both structured and fast, from core architecture to production delivery.

In my current role, I co-built and shipped a live e-commerce platform for children’s toys end-to-end with a peer developer, reaching a published Play Store release. I’ve also led performance optimization ahead of deployment, improving load times and stability across product browsing and checkout flows.

I’m comfortable owning dynamic user experiences, including advanced product browsing with filtering by Category, Brand, and Age Group and client-side sorting. I also engineered persistent Cart & Wishlist functionality using the React Context API for centralized state management across sessions.

Outside that work, I built an end-to-end Wallpaper Application that integrates the Pexels API for keyword search and category filters, packaging a public APK release. I like taking projects from UI design through API integration, and I document and share progress through a well-maintained GitHub repository and a public video walkthrough.
