Senior data engineer building scalable, cost-efficient data platforms and reliable pipelines.
IndonesiaWhat I'm looking for
I’m a Senior Data Engineer with 5+ years of experience designing and operating scalable, cost-efficient data platforms across cloud environments. I specialize in SQL, Python, and data modeling, building end-to-end data pipelines, data warehouses, and API-based data services that improve reliability, optimize costs, and enable data-driven decision making.
In my recent work, I delivered ingestion → warehouse → API platforms and reduced warehouse costs by 20–30% through query optimization and partitioning. I’ve led initiatives like cloud-to-on-prem migration (BigQuery to Cloudera HDFS), automated ingestion workflows to cut manual ETL by ~80%, improved pipeline performance by ~50%, and supported teams with architecture, governance, and ETL best practices—so analytics stays fast, trustworthy, and ready for business needs.
