Chennai · IST( About me )
Engineer first. I like systems that keep working at 3 a.m.
I'm a Software Engineer at HCL GUVI with 3+ years of experience designing scalable AI-powered, cloud-native platforms using Python, FastAPI, React, AWS and Docker. I've shipped production generative AI features, real-time voice systems and the CI/CD, observability and security that sit underneath them.
I debug distributed systems for fun, mentor teammates, and keep a strong footing in data structures and algorithms. I've also volunteered as a mock-interview panelist for students at the Maatram Foundation, and run a backend (PHP & MySQL) workshop for ~35 juniors.
