What I'm looking for

I’m looking for a role where I can deliver product and marketing analytics end-to-end—building reliable pipelines and dashboards, running experiments like A/B tests, and partnering closely with technical and business teams to turn insights into action.

I’m a seasoned Senior Data Analyst with over 7 years of experience in Data Analytics & Business Intelligence, focused on delivering advanced data-driven solutions that enhance decision-making and operational efficiency. I extract valuable insights from complex datasets by creating clear, powerful data visualization spaces, particularly for projects dedicated to Product, Marketing, or general Business Intelligence analytics.

I’m extensively experienced in structuring complex queries in Snowflake and SQL Server, and coding with Python or R libraries to support robust analytics. Since starting as a Data Analyst and being promoted to Senior Data Analyst in October 2021, I also act as a Project Manager for projects for the company’s top client, serving as a liaison between Technical, Business, or Product teams while communicating impactful insights with great attention to detail—using Tableau, Power BI, Metabase, Looker, and strong ETL/data integration practices.
