I am currently working as a Full Stack Developer at current organisation , where I develop and maintain end-to-end web applications for various business domains. My role involves designing, developing, testing, and deploying scalable applications while ensuring high performance and maintainability. During my tenure, I have worked on CRM (Customer Relationship Management), ERP (Enterprise Resource Planning), and E-commerce platforms. I have been responsible for building complete solutions, including frontend development, backend API development, database design, and deployment. I collaborate with cross-functional teams to understand business requirements and transform them into efficient technical solutions. On the frontend, I use React.js, Next.js, TypeScript, Tailwind CSS, and Material UI to create responsive, user-friendly interfaces with reusable components. On the backend, I develop secure RESTful APIs using Node.js and Express.js, implement authentication and authorization, integrate third-party services, and optimize application performance. I also manage MongoDB and MySQL databases by designing schemas, writing optimized queries, and ensuring data consistency and security. In addition, I use Git for version control, participate in code reviews, fix bugs, optimize existing features, and contribute to improving the overall code quality. Working on enterprise-level applications has strengthened my understanding of the complete software development lifecycle, from requirement gathering and system design to deployment and maintenance. These experiences have enhanced my problem-solving skills, technical expertise, and ability to deliver reliable, scalable, and high-quality software solutions in a collaborative and fast-paced development environment.
