What I'm looking for

I seek a collaborative environment where I can leverage my front-end skills to create impactful applications and grow professionally.

As a front-end engineer with three years of professional experience, I specialize in building scalable React platforms and theme-driven design systems. My journey has been marked by a passion for crafting reusable UI libraries and enhancing developer productivity through high-speed CI/CD pipelines. I have a strong foundation in React 18, CSS3, and various testing frameworks, which allows me to deliver high-quality, maintainable code.

At WAi Technologies, I architected a theme-driven React design system that significantly reduced feature lead-time and improved UI consistency across multiple micro-frontends. My work on optimizing code-splitting and implementing a Lerna monorepo has led to substantial improvements in performance and build times. I take pride in maintaining high unit and interaction coverage, ensuring reliable releases that meet the needs of our users.
