I’m a Full-Stack Developer with 3+ years of experience designing, developing, and maintaining scalable web applications. I focus on delivering end-to-end features that improve user experience while keeping backend services reliable and maintainable.

I bring strong expertise in React.js, Next.js, JavaScript, TypeScript, Node.js, Express.js, and REST APIs, along with PostgreSQL, MySQL, and MongoDB. I’ve implemented JWT authentication and role-based access control, integrated third-party APIs, and built responsive, cross-browser compatible user interfaces, while optimizing performance through techniques like code splitting, lazy loading, and query optimization.

In Agile environments, I collaborate with UI/UX designers, QA teams, and stakeholders through sprint planning, code reviews, and production deployments. From e-commerce and learning management systems to internal portals, I’ve contributed to building reusable components, modular architectures, and secure, workflow-driven systems.
