What I'm looking for

I’m looking for a role where I can build SQL-powered KPI dashboards in Power BI/Tableau, strengthen data quality and validation, and deliver management-ready insights with clear reporting logic and strong stakeholder collaboration.

I’m a Data Analyst with 5 years of experience in SQL reporting, Excel analysis, Tableau dashboard development, and monthly reporting—turning messy operational data into stakeholder-ready business summaries. I’m known for maintaining data accuracy below 0.01% error rate, sustaining validation performance above 99.87%, and building enterprise dashboard modules that improve management visibility.

At PT TASPEN (Persero), I supported dashboard development end-to-end—from requirement review and visual design to filter logic, data validation, testing, documentation, and stakeholder review using SQL Server-based reporting architecture. I strengthen data reliability through cleaning, structuring, discrepancy identification, and clear reporting logic documentation, and I’m currently focusing on Power BI data modeling, DAX, advanced SQL, and Python for analytics (including GitHub-driven BI dashboard and reporting automation projects).
