About

As a Full Stack Engineer at KRS, I lead the migration of a legacy PHP backend to Node.js, enhancing scalability and performance. I also designed a scalable CRM system and developed AI-powered features, including chatbots, behavior-driven course recommendations, and WhatsApp automation. My work includes delivering modern, responsive interfaces using React.js and Next.js, while ensuring seamless frontend-backend integration with RESTful APIs and robust authentication layers. Currently pursuing a Bachelor of Technology in Computer Science at Kalasalingam University, I bring a strong foundation in production readiness, web development, and chatbots. I am passionate about leveraging technology to create impactful, scalable solutions that meet organizational and user needs.
