Backend engineering Applied AI

Open to Summer 2027 internships

I like figuring out
how the pieces fit.

I spent three years at TransUnion working with Java, Spring, APIs, and data. Now I’m pursuing my MS in Computer Science at Stony Brook.

In my own projects, I’m building with LLMs, vector search, background workers, and MCP.

01 EXPERIENCE

Built on experience.

~3 years at TransUnion

TransUnion

Intern → Associate Developer

2023 – 2026

My work covered backend services, customer data migrations, and payment transaction defects. It taught me to follow a problem through the different parts of a system.

Java & Spring backend services

Developed backend services and API integrations, and worked through issues.

Data migrations & payment fixes

Worked on customer data migration pipelines and resolved payment transaction defects.

04 ABOUT & TOOLKIT

Always something to figure out.

From Pune to Stony Brook.

I’m pursuing my MS in Computer Science at Stony Brook University, with graduation planned for May 2028. I’m also a teaching assistant for CSE 214, helping students work through data structures.

Before that, I studied Electronics & Telecommunication Engineering at VIT Pune and spent three years in software development at TransUnion.

I’m interested in backend engineering, distributed systems, and building useful AI applications. My projects are where I try new tools and work through how they fit together.
