About Me.

I'm a Full Stack Developer from Dhaka, Bangladesh, specializing in building modern web applications with Next.js, TypeScript, and AI integration.

I craft scalable, high-performance solutions — from pixel-perfect frontends to robust backend architectures — with a focus on clean code and exceptional user experiences.

Currently building AI-powered applications at KI-Quadrat, a Vienna-based AI company, where I integrate conversational AI, workflow automation, and intelligent features into production systems.

Agentic Engineering.

I don't just use AI agents. I know where they break.
