FOCUS

WEB / SYSTEM / AI

Saya adalah lulusan Teknik Informatika dari Universitas Gunadarma (IPK 3.74) yang berfokus pada rekayasa web aplikasi, sistem backend, otomasi kecerdasan buatan, dan administrasi infrastruktur server Linux.

Perjalanan saya dimulai dari level perangkat keras: mendiagnosis kerusakan motherboard di Ansi Cellular, mengonfigurasi jaringan LAN di PT Mega Pillar Mas, hingga mengelola operasional marketplace e-commerce di ikiytech dan PT Baja Inti Prima. Fondasi ini membentuk pola pikir eliminasi logis yang saya terapkan saat membangun sistem web modern.

Bagi saya, perangkat lunak tidak berjalan di ruang hampa. Keandalan aplikasi bertumpu pada pemahaman menyeluruh: mulai dari antarmuka pengguna, efisiensi database relasional, keamanan protokol API, hingga kestabilan server host di cloud.

HOW I THINK ABOUT SYSTEMS

LAYER 01 OF 06
SYSTEM ARCHITECTURE

User Intent

Client & Human Experience

Every software architecture begins with human intent: accessing information, submitting transactions, or requesting a service. A well-designed system reduces friction and provides clear, immediate feedback.

Personal Perspective

“As a developer, I treat user interaction not as an afterthought, but as the governing constraint that shapes the entire system down to the database schema.”

PERSPECTIVE

CODE IS STATIC.
THE EXPERIENCE ISN'T.

Systems engineered with intent, executed with precision.
