What I'm looking for

I’m eager to grow as a developer and deliver clean, maintainable solutions in a professional team.

At The Emerson Empire, I engineered a responsive React and Tailwind CSS website presenting the agency’s services and programs. I also built reusable UI components for a consistent desktop and mobile experience.

At PT. Cihampelas Cerdas Mandiri, I delivered a company website that improved access to accommodation information. I worked with stakeholders to translate business needs into website features and clearer content.

On MindCheck, I developed a full-stack application using Next.js and FastAPI that classifies stress levels with a Random Forest model. I’ve also integrated RESTful APIs into frontend projects and developed Android applications with Kotlin.
