As a MERN stack developer, my role in the team involves building web applications using the MERN stack, which includes MongoDB, Express.js, React, and Node.js. I work on both front-end and back-end development, ensuring the seamless integration of these technologies. On a daily basis, I use JavaScript, React for creating user interfaces, Express.js and Node.js for server-side development, and MongoDB for database management. Collaboration with the design and product teams is essential to deliver high-quality web applications, and problem-solving and debugging skills are crucial for addressing issues that arise during development.
