I currently work as a Software Engineer with Gupshup.

I am involved in the computing community by volunteering at ACM. I have been an editor with ACM XRDS, and I’m now a member of the ACM Future of Computing Academy (FCA). You can find the work that FCA is doing at https://acm-fca.org/

My professional work and interests include working with Java, Spring Boot and related ecosystems, and learning about designing Scalable Software Architectures and Systems.

My favourite IDE is IntelliJ IDEA!
