Hi, I'm Efazul Karim
Building scalable full-stack systems and automation-driven products for real-world businesses.
The developer behind the code
A bit about who I am, what I build, and the tools I reach for.
My Journey
I build full-stack web apps, mobile apps, backend systems, and AI-assisted tools that save time and scale reliably. Specializing in React, Next.js, React Native, Python, Node.js, and Docker across frontend, backend, mobile, and automation.
I work end-to-end — React, Next.js and TypeScript on the front, React Native for cross-platform mobile, and robust APIs, microservices and databases with Node.js and Python behind them. I care about clean, maintainable code and interfaces that feel effortless on every platform.
