My Projects
EarthLink (Internet Service Provider)
I engineered core modules including a custom in-house Payment Gateway, eCommerce Checkout, and Agent Console. Utilizing a MERN-based Microservices architecture, I integrated Twilio and Google APIs to build secure, pixel-perfect user on-boarding flows. My focus on performance optimization and technical leadership directly reduced the bug backlog by 40% while bridging the gap between complex backend logic and intuitive, high-traffic frontend interfaces.
Rapid Store (Ecommerce)
Engineered a high-performance e-commerce architecture featuring a secure Razorpay Payment Gateway integration with server-side Signature Verification for transaction integrity. I optimized the user experience by implementing Debouncing logic on search queries to minimize API overhead and integrated JWT-based Authentication with Private Routing to secure sensitive user flows. The application manages complex Cart and Wishlist states alongside dynamic Filtering and Sorting algorithms, all wrapped in a Mobile-First, Responsive design built with CSS Grid and Flexbox for seamless cross-device performance.
DigiMantra Labs site (Portfolio/Landing Page)
I've worked on making landing page pixel-perfect design and integrated chatbot. Integrated GraphQL to show data coming from backend
