About Me

Creative Developer & Designer

I am a Full Stack Developer with hands-on experience in building and maintaining enterprise-grade healthcare systems and mission-critical web applications. Currently at PT. Graha Medika (Rumah Sakit Umum Pekerja), I leverage Laravel and MySQL to develop robust internal systems, optimize Hospital Information System (HIS) workflows, and engineer seamless third-party integrations, including BPJS bridging and Mobile JKN services. My expertise spans end-to-end web development, RESTful API architecture, database management, and active system troubleshooting to guarantee high availability and operational reliability. Dedicated to writing clean, maintainable code, I focus on bridging complex business and medical requirements into secure, high-performance, and user-centric digital solutions.
