Rayhan K., Frontend Developer

Description

I help teams fix and scale complex frontend systems when delivery slows down

and the codebase becomes hard to evolve. Focused on improving frontend architecture, stabilizing design

systems, and integrating efficiently with backend services to increase reliability, speed up development, and

support sustainable product growth.

Currently collaborating with web design agencies, I’m open to a full time contract and new projects to bring innovative ideas to life.
