(01)About

I'm a Software Engineer I at RackBank Datacenters, where I work on NeevCloud and Zata, an S3-compatible object storage platform, using Next.js and TypeScript. I graduated in 2026 with a B.Tech in CSE from Indore Institute of Science and Technology.

Local time --:-- IST

I joined RackBank as a Full Stack Developer Intern in May 2026 and moved to a full-time Software Engineer I role in August. I work on NeevCloud and Zata with Next.js, TypeScript and JavaScript, and we deploy them to our own virtual machines through GitLab. Working on an object storage platform taught me how buckets, the S3 API, pre-signed URLs and access policies work in practice, and I used that in my own project, the Zata S3 File Explorer.

Before RackBank, I interned at VyanWebs, where I built a full-stack app with Next.js, TypeScript and PostgreSQL. On my own I've built MERN projects with React, Node.js, Express and REST APIs, including a quiz platform that generates a quiz on any topic and shows you where you went wrong.

Most of my work is in JavaScript and TypeScript. Outside work I solve problems on LeetCode and other platforms, which keeps my data structures and algorithms practice regular.

Why is binary search O(log n)?

AI tutor

Every step compares the middle element and discards half of what's left — n, n/2, n/4… — so it finds the target in about log₂ n steps.
