Hi, I'm Sumayea Rahman
Full-Stack Software Engineer
Transforming ideas into modern, high-performance AI applications with Next.js, React, TypeScript, and Node.js.

About Me
I build software that turns real-world problems into practical, reliable solutions.

I build software with a focus on solving real problems, designing reliable systems, and continuously improving how things work.
I'm a Full-Stack Software Engineer focused on building modern, scalable web applications. I work across the stack with TypeScript, React, Next.js, Node.js, PostgreSQL,and related backend and cloud technologies.
I enjoy working beyond just writing features — from designing APIs and database structures to implementing authentication, integrating third-party services, debugging complex issues, and deploying applications. I care about writing clean, maintainable codeand understanding the systems I build rather than simply making them work.
My background in business and finance also influences how I approach engineering. I naturally think about problem-solving, users, trade-offs, and business value alongside technical decisions. I'm continuously deepening my knowledge of software engineering, system design, and AI-powered development to build better and more reliable products.
