As a MERN Stack Developer, I specialize in building dynamic and scalable web applications using MongoDB, Express.js, React, and Node.js. I handle both front-end development, creating responsive user interfaces with React, and back-end development, including building RESTful APIs and managing server-side logic with Node.js and Express. I also integrate Twilio for features like SMS and WhatsApp messaging, as well as setting up automated reminders and real-time notifications. Additionally, I manage the deployment and performance optimization of applications on VPS, ensuring they are scalable, secure, and reliable.
