Transforming Complex Data into Clear Insights and Smarter Business Decisions

The true value of data is not in how much information an organization collects, but in how effectively that information drives results.

With 15 years of experience in business intelligence, data operations, analytics, and market research, I help organizations turn fragmented, complex data into actionable insights that improve efficiency, uncover opportunities, and drive business performance.

My specialty is bridging the gap between raw data and meaningful business intelligence. Since 2013, I've designed and developed interactive Tableau dashboards, streamlined data preparation processes, and built scalable reporting solutions that make information accessible, intuitive, and impactful.

What I Bring to Your Business:
• Business Intelligence & Data Visualization: Design polished, interactive Tableau dashboards that simplify complex information, track KPIs, and empower stakeholders to make data-driven decisions.
• Data Preparation & Automation: Leverage Alteryx, Tableau Prep, and Excel to clean, transform, integrate, and automate data workflows, reducing manual effort and improving reporting consistency.
• Data Integration & Reporting: Work with diverse data environments, from Excel spreadsheets to enterprise platforms including Salesforce, Snowflake, Google BigQuery, and AWS.
• Dashboard Optimization: Improve dashboard usability, performance, and visual presentation to deliver a seamless end-user experience.
• Strategic Analysis & Insights: Translate business requirements into meaningful metrics, identify trends, and deliver reporting that supports operational and strategic objectives.
• End-to-End Project Delivery: Manage projects from discovery and data assessment through development, implementation, and ongoing optimization, collaborating with stakeholders and leveraging tools such as Jira, Asana, monday, and Slack.

Why Work With Me?
I combine technical expertise with a business-first mindset. Having supported organizations across healthcare, retail, education, and other industries, I understand that successful analytics solutions require more than technical execution. They require thoughtful design, reliable data, and a clear understanding of the decisions stakeholders need to make.

I take pride in delivering solutions that are not only technically sound and visually compelling but also practical, scalable, and aligned with business goals.

Let's turn your data into a competitive advantage.
