I led the front-end development for E-SISMAL (the Malaria Information System) at the Ministry of Health of Indonesia, creating complex case-reporting forms and national surveillance dashboards using React.js and Bootstrap. I also developed the JumpaDokter telemedicine platform, designing seamless user flows for online consultations and doctor appointment scheduling to ensure an efficient booking experience for patients. In addition, I built the DigiHealthSpace e-learning platform, focusing on interactive course modules and optimizing video rendering to deliver a smooth learning experience across devices. Throughout these projects, I implemented strict data-validation logic and integrated RESTful APIs to ensure accurate data submission for high-traffic healthcare systems.

I developed the E-Recruitment portal for PT Bukit Makmur Mandiri Utama (BUMA), optimizing the job application process for candidates and creating an intuitive HR admin dashboard using Vue.js and TypeScript. I also built enterprise-grade E-Procurement systems for major clients such as Astra Otoparts, Arya Noble, and Trakindo CAT, managing complex vendor-management workflows, dynamic data tables, and secure authentication flows. In addition, I translated Figma designs into pixel-perfect UI components to ensure consistent branding across multiple corporate platforms. I also conducted performance optimizations—including lazy loading and code splitting—which significantly improved load times for data-heavy dashboards.

I designed and developed an e-learning platform for UMKM, enabling small business owners to access digital training materials through a mobile-first, responsive web interface. Additionally, I built essential CRUD features for an internal web application using HTML, CSS, and JavaScript within a Laravel stack, ensuring reliable and efficient data management.
