I'm a CSE graduate from American International University-Bangladesh (AIUB) focused on full-stack and backend development.

I enjoy turning ideas into complete software systems — from database design and REST APIs to responsive frontend interfaces and authentication workflows.

I recently worked as a Software Engineer Intern at XR Interactive, where I contributed to EventX, a full-stack event management platform built with Next.js, NestJS, PostgreSQL, and Prisma.
