Journey
Hi, I’m Akshat Jain, a passionate Full Stack Developer with a strong foundation in problem-solving and web development. I recently completed my B. Tech in Computer Science and Engineering from Bharati Vidyapeeth's College of Engineering, New Delhi. My journey in tech started with competitive programming, where I ranked 3rd in my institute in a coding competition and solved 600+ DSA problems online. I gradually transitioned into full-stack development, working with React, Node.js, Express, and MongoDB to build scalable web applications. I have worked on several impactful projects, including Coursify, a Learning Management System, and FoodGenix, an e-commerce food ordering platform. I also contributed to open-source projects in Hacktoberfest and JGEC Winter of Code. In my professional journey, I interned as a Full Stack Developer at Jarvis Technology and Strategy Consulting, where I worked on optimizing backend systems using Ruby on Rails and developing frontend interfaces with React and Angular. I’m always excited to learn new technologies and solve challenging problems, and I look forward to contributing my skills and experience to impactful projects.
