What I'm looking for

I'm looking to build automated data systems, ETL pipelines, and dashboards that replace manual work, improve reporting, and turn complex business data into actionable insights.

I turn chaotic data into automated systems that save time and support better decisions. Recently, I helped a telecom contractor reduce payroll processing from a full day to under an hour.

At Kementrian Koordinator Bidang Perekonomian, I built fraud-monitoring data pipelines, automated reporting, reconciliations, email and SMS marketing campaigns, and dashboards using Python, Jupyter Notebook, Metabase, MySQL, Google Sheets, and Alibaba Cloud.

At Tiket.com, I developed and managed Tableau dashboards, presented product insights, administered Tableau Server, and built data marts and data warehouses for stakeholders. I also trained users to work confidently with dashboards.

My experience began in ERP consulting and technical operations, giving me a practical bridge between infrastructure, business processes, and analytics. I enjoy removing repetitive work through ETL pipelines, automation, reporting, and clear data visualization.
