Backend Automation & Data Engineer building ETL pipelines, monitoring systems, and workflow automation with Python & SQL.

What I'm looking for

I want to build backend automation, ETL pipelines, and internal systems that improve operational efficiency, data consistency, and reporting reliability. I enjoy transforming manual workflows into scalable automation systems using Python, SQL, and data-driven processes.

I’m a Backend Automation & Data Engineer focused on building internal systems, ETL workflows, monitoring automation, and SQL-based data processing to improve operational efficiency and reporting reliability.

At PT Pelita Air Service, I developed backend automation and monitoring systems that reduced downtime by up to 80% while improving operational and financial reporting workflows. I also built automation scripts for backup, validation, reconciliation, and repetitive operational processes using Python, PHP, SQL, and database-driven workflows.

My work focuses on transforming manual processes into scalable and reliable automation systems. Through projects such as Financial Journal Automation System and ETL & Data Integration Workflow, I reduced processing time from around 2 weeks to under 2 hours while improving data validation and reporting accuracy.

I’m especially interested in backend automation, ETL pipelines, operational systems, internal tools, workflow optimization, and data engineering.
