BI & Data Analyst
I’m a BI & Data Analyst with a strong foundation in SQL, Python, Tableau, BigQuery, dbt, and Databricks — passionate about transforming complex datasets into clear, actionable insights.
​
With over 20 years of experience in payroll and finance, I bring a business-first perspective to analytics.
​
I’ve built interactive dashboards, written complex queries, cleaned and structured messy datasets, and designed ETL/ELT pipelines — always with the goal of making data truly serve the business.

What I Bring
🔹 A business-first mindset rooted in finance and payroll expertise
🔹 Strong process optimization skills
🔹 A knack for turning data into meaningful stories
​
I’m a people-oriented professional who thrives in collaborative environments but also enjoys working independently. I value honesty, work hard, and approach challenges with curiosity and positivity.
​
Outside of work, you’ll find me mountain biking, taking long walks, solving puzzles, or getting lost in a good book.
​
🚀 Next Steps
I’m seeking an entry-level data analytics role where I can combine my analytical skills with my financial background to deliver valuable insights and support data-driven decision-making. I’m eager to contribute to impactful projects in a collaborative, innovative environment while continuing to grow my technical expertise.
