Del Wester

I am a results-driven Data Analyst with over a decade of experience transforming raw data into meaningful insights that support smarter business decisions. My expertise spans across Python, SQL, AI (Artificial Intelligence), Spark, Power BI, and Databricks, enabling me to tackle a wide range of data challenges from end to end.

My career has centered on building efficient, scalable workflows to process and analyze complex datasets. I have worked extensively with structured and unstructured data, developing solutions that not only uncover key trends but also empower decision-makers to act quickly and effectively. Whether it’s building predictive models with AI, writing optimized SQL queries for high-performance databases, or designing intuitive dashboards in Power BI, I approach every project with a focus on clarity, usability, and measurable results.

In Python, I leverage libraries such as Pandas, NumPy, and LangChain/LangGraph to create automation pipelines, predictive analytics, and data transformations. With Spark and Databricks, I handle large-scale data processing, ensuring performance and reliability when working with enterprise-level datasets. My experience with SQL spans both operational and analytical contexts, from query optimization to data validation and ETL processes. These skills come together to provide comprehensive solutions that connect the technical aspects of data management with the strategic needs of the business.

Beyond technical ability, I pride myself on communication and collaboration. I work closely with stakeholders to understand their goals, translate complex analysis into clear business narratives, and deliver solutions that directly align with organizational objectives. I have also mentored team members in adopting best practices for analytics and reporting, ensuring that data is accessible and actionable at all levels.

Looking ahead, I am particularly excited about the growing role of AI and machine learning in driving business innovation. I believe the future consists of combining automation, predictive modeling, and interactive reporting to create systems that continuously adapt and improve decision-making. My mission is to help organizations harness this potential, bridging the gap between raw data and strategic outcomes.

If you are looking for a data professional who combines technical expertise with business-focused insight, I bring the skills, experience, and forward-thinking approach to help you succeed.
