At PTApex Mitra Malindo, I optimized HRIS attendance processing through database cleanup and SQL indexing, reducing execution time from approximately three seconds to one. I also developed a camera-based employee photo capture feature for the existing Laravel application.
In the Helpdesk system, I optimized SQL queries and Eloquent ORM operations, reducing CSV export time from approximately 30 seconds to four while improving import performance. I also maintained production Laravel applications, resolved bugs, and supported cPanel deployments.
As an Independent Web Developer, I developed three paid academic web application prototypes for individual clients, handling implementation across database design, authentication, business workflows, and service integrations. My projects include Bengkel Rutin, a workshop management and scheduling system, and Hoaxlin, a multimodal hoax detection platform.
