About Mahfuz
Full Stack Developer | React.js , Next.js , Node.js | MERN Stack
Dhaka, Bangladesh - 11:04 am local time
I work across the full stack: React.js and Next.js frontends, Node.js/Express.js APIs, PostgreSQL and MongoDB databases.
I convert Figma designs into pixel-perfect interfaces, build secure REST APIs, add authentication, integrate third-party services, and take ownership from first commit to live deployment.
I don't just finish tasks. I build software that works, is easy to maintain, and supports real business goals. If something isn't right after delivery, I fix it.
