About

I'm a software developer and Computer Science undergraduate at Chennai Institute of Technology. I enjoy turning ideas into working products, building web applications, backend APIs, and data-driven tools with React, Next.js, Node.js, and Python.

As a Data Engineering Intern at RenewCred, I worked on cloud observability, monitoring dashboards, and infrastructure visibility. As an SDE Intern at Tesys India Private Limited, I built backend APIs and real-time features for logistics applications. These experiences taught me to adapt quickly to fast-paced environments and ship useful features faster, while keeping reliability and user needs in focus. I like learning a new stack, understanding the problem, and turning that understanding into something people can use.

As an OpenAI Student Collective Campus Lead, I help students explore AI through workshops and hands-on learning. I value teams that share knowledge, ask good questions, and care about the people using what they build. I'm open to software engineering opportunities and collaborations that let me contribute and keep learning.
