What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

I am a strategic Data Analytics Specialist with over 8 years of experience in driving actionable insights through scalable, data-driven solutions. My expertise lies in SQL, Python, AWS, Tableau, and Power BI, which I have utilized to fuel business improvements by translating complex requirements into reliable dashboards and reports. I excel at collaborating with stakeholders to optimize processes and enhance efficiency across diverse industries.

In my current role as a Sr. Business Intelligence Specialist at Assembly Global, I have led performance tuning initiatives that optimized complex SQL queries, achieving a remarkable 5x improvement in data processing speed. My efforts in automating data pipelines have reduced manual effort by 30%, while my work in optimizing ETL pipelines has significantly boosted ingestion speed and reliability. I have also successfully migrated reporting workflows to BigQuery, resulting in substantial cost savings and improved system reliability.

Previously, I worked as a Business Analyst at Amazon, where I automated KPI reporting workflows and delivered actionable insights that shaped customer acquisition strategies. My experience at IBM as a Data Analyst involved building interactive Tableau dashboards and utilizing Python for data cleansing, which improved operational efficiency. I am passionate about leveraging data to drive business success and am always eager to take on new challenges.
