About Me

I graduated from Universitas Indonesia in 2025 with a bachelor's degree in Computer Science.

I'm a software engineer focused on backend systems — building payment platforms, web service interfaces, and real-time data streaming services with Apache Kafka, most recently for Indonesia's banking industry at OpenWay. I enjoy turning complex requirements into clean, reliable software.

When I'm not debugging, you'll find me watching YouTube videos or curating my Spotify playlists.

Ordering Service & Shipping Variations in a Webshop Product Line

Developed with Prices-IDE · Student Collaborator, Reliable Software Engineering Laboratory (RSE Lab) — Faculty of Computer Science, Universitas Indonesia · 2025

Applied Software Product Line Engineering (SPLE) to a webshop: modeled category and address management, shopping carts, and configurable delivery mechanisms, and refactored the catalog, ordering, and payment features. Built with Prices-IDE, the backend is generated as WinVMJ (Java) from UML-DOP diagrams and the frontend as ReactJS from IFML-DOP diagrams. Applies Multi Product Line (MPL) by integrating Payment Gateway and Authentication product lines, validated by functional testing on five derived products and load testing on backend endpoints.
