I build software
that works reliably,
even under pressure.

Full stack developer focused on backend architecture, web development, and system integration. I enjoy building things that keep working well not just on launch day, but as traffic and complexity grow.

JakEdu
Educational Platform API2025 - 2026

JakEdu

JakEdu is the internal platform Pusdatin Dinas Pendidikan DKI Jakarta uses to manage access across several education systems (Selaras, KKI, and Dapodik). Access used to be handled manually through direct database queries. I built a centralized Master Data module (Users, Applications, Roles) backed by a PostgreSQL schema using Role Based Access Control, so admins can grant or revoke access in a few clicks and see clearly who has access to what.

Nibiru

Nibiru is an e-commerce platform for selling merchandise and digital literary works. I built both the user-facing storefront and the admin panel, using Laravel and PostgreSQL, with Xendit for payments and Biteship for shipping.

The Reality Check.

Before we partner up, let’s address the elephant in the room. Why precision in software engineering matters.

You can, for a simple site. But once your product needs to handle real traffic or grow over time, the difference shows: how easy it is to add a feature or fix a bug without breaking everything else. That's what I focus on getting right from the start.
