About Me

From factory floors to production servers.

I'm an Information Technology student at President University focused on full-stack web development, from building interfaces with Tailwind CSS, to designing and keeping the backend and SaaS bot rental systems for WhatsApp & Telegram running optimally 24/7.

The technical scope I work on includes payment gateway integration (such as QRIS and webhooks with HMAC signatures), all the way to configuring and operating VPS servers (Linux/Ubuntu) in production environments.

Before moving into software, I worked as a production operator at PT Denso Indonesia and PT AKS Precision Ball. That industrial experience taught me the importance of teamwork, effective communication, and a high level of discipline, values I now apply to building reliable, measurable systems.
