About

I am Sugan G, a Full Stack Developer at Chakraa Universal Tech Labs with 1.4 years of experience building and deploying scalable web applications. I have worked on domains such as billing platforms, AI chatbots, and analytics dashboards using technologies like React.js, Node.js, Express.js, and Zoho Catalyst. My work has led to measurable improvements, including a 30% reduction in UI development time, a 40% decrease in communication errors, and a 25% reduction in manual effort through automation. I am particularly strong in designing REST APIs, implementing secure authentication systems, and delivering responsive UIs. I am looking for new opportunities to further grow as a Full Stack Developer and contribute to impactful projects.
