I’m an Analytics Developer with over 4 years of experience across analytics and data roles, specializing in SQL development, data modeling, and pipeline optimization. I focus on improving the reliability and usability of complex, legacy data backends.

In my current role, I led complex SQL development and optimization projects with independent ownership of legacy data areas to improve backend robustness and query performance. I built and maintained end-to-end data pipelines for global supply chain operations, acting as a primary point of contact for complex data issues.

I also develop KPI-focused Tableau dashboards and drive team alignment by documenting standard operating procedures (SOPs) and data workflows in Confluence and Miro. To reduce technical debt, I audited and cleaned large-scale datasets in Google BigQuery to prepare environments for future-state analytical models.

Previously, I managed APAC forecasting data processes, reduced reporting timelines through Power Query-based validation, and maintained Power BI dashboards for key stakeholders. Earlier, I automated data transformation with Python and SQL ETL scripts, monitored daily ETL operations, and ensured data integrity using Excel control workbooks with Power Query and VBA.
