Software, systems,
and a curiosity for space.
I’m a fullstack engineer at Samsung R&D Indonesia. My work spans applications, data pipelines, and AI tools. I’m also exploring software for space and ground systems.
About me
A little about my work
From the interface to the infrastructure.
Data engineering
Useful data, at scale
My work at tiket.com connected distributed scraping, reverse engineering, and cloud pipelines to the decisions behind pricing.

Distributed data platform
A distributed data platform built on resilient web scraping. Collecting hotel and flight data, then turning it into pricing intelligence.

Inside the scraping platform
Built distributed scraping and custom extraction frameworks, with reverse engineering to keep data acquisition resilient. Enterprise-scale ETL carries the results through Google Cloud Storage and BigQuery. An ad-hoc exploration service roughly doubled data-exploration speed while the platform reduced third-party data costs.Proprietary work at tiket.com.
