About

Hello! You can call me Leo. I'm a Frontend Developer with full-stack experience based in Ho Chi Minh City, Vietnam. I specialize in building performant, SEO-driven, and user-centric web applications.

I primarily work with React and Next.js on the frontend, while also developing and integrating backend services using ASP.NET and REST APIs. My experience includes working with Google Analytics, SEO optimization, and CMS platforms such as WordPress (Elementor) and Microsoft Power Pages with Dataverse.

I focus on delivering scalable, maintainable solutions that not only look good but also perform well and provide measurable business impact. I enjoy collaborating across teams, improving system performance, and continuously learning new technologies.
