What I'm looking for

I seek a collaborative environment that fosters innovation and growth.

I am a proficient Frontend Engineer with extensive experience in both frontend and backend development, specializing in modern web technologies such as React.js, Next.js, and TypeScript. Currently, I am building Paydeet, a centralized banking identity platform, where I lead the technical implementations of key features. My work at Devheit has allowed me to enhance my skills in developing user-friendly applications that prioritize performance and scalability.

Previously, I led the overhaul of WiredAssurance's frontend, achieving a remarkable 40% improvement in performance and maintainability. My freelance projects have further honed my problem-solving capabilities, particularly in Data Structures and Algorithms. I am passionate about creating responsive and interactive user interfaces that not only meet client expectations but also enhance user experience.
