Data Engineer, writing from Jakarta
Hi, I’m Rezha.
For the last 11+ years I’ve built the pipelines that quietly move data in the background, currently at Gojek and before that at Traveloka. Outside of work, I help organize PyCon Indonesia and the PythonID meetup here in Jakarta.

A little about me
I’ve spent over a decade turning messy, high-volume data into systems people can actually rely on, right now on Gojek’s financial data platform and before that at Traveloka. Outside of work you’ll usually find me at a PyCon Indonesia or PythonID meetup.
Curious about the tools? Python, Go, Kafka, BigQuery, and lately a growing pile of AI agents.
