About

Final-year B.E. Computer Science student with hands-on software development experience at WizCommerce, where I work on production-grade full-stack features for a multi-tenant B2B e-commerce platform serving 30+ live storefronts. My core strengths are Java, REST APIs, MERN stack development, microservices-style architecture, MongoDB, PostgreSQL/MySQL, Git, Docker, and cloud fundamentals. I enjoy building backend APIs, improving frontend-backend integration, optimizing data fetching, and writing clean, maintainable code. At WizCommerce, I have worked on React + WordPress frontend integrations, direct browser-to-backend API calls, reusable UI widgets, design-token-based styling, and performance improvements across API-heavy pages. I am especially interested in backend engineering, distributed systems, event-driven architecture, cloud-native applications, and AI/data engineering.
