I began my career as a Full Stack Developer with a start-up that primarily used the LAMP stack (Linux, Apache, MySQL, and PHP). I was involved in numerous projects, of which a Customer Relationship Management (CRM) system was the most significant one. It required designing a robust backend using PHP and MySQL and creating a user-friendly frontend with vanilla JavaScript and AJAX calls.
Realizing the trend of JavaScript frameworks, I self-learned React, and eventually, we transitioned from the LAMP stack to the MERN stack (MongoDB, Express.js, React, and Node.js). This transition enhanced my expertise and brought about a marked improvement in the efficiency of our projects, including reducing the CRM system's load time by about 45%.
