About

I am a Software Engineer at Tekion Corp, a leading cloud-native commerce platform provider, where I deliver high-performance and scalable solutions for e-commerce clients. With a Bachelor of Engineering degree from Netaji Subhas Institute of Technology, I have a strong background in full stack web development, using multiple technologies such as Java, Python, JavaScript, React, and HTML. At Tekion, I have successfully identified and resolved critical performance bottlenecks, resulting in a 40% improvement in page load times. I have also led the end-to-end delivery of new features and actively participated in evolving the architecture for performance and scalability. In addition, I have mentored and trained team members, contributing to team productivity and growth. I have also demonstrated adaptability and expertise in using new technologies, such as Perspective, an open source framework for data visualization, which I used to build a live tool for stock price analysis. I am passionate about learning new technologies and solving complex problems with innovative and efficient solutions.
