Senior BI Developer with 6+ years turning complex data into clear, actionable insights. Now bridging the gap between data intelligence and modern web development.
Hi, I'm Cynthia, a Senior BI Developer specializing in full-stack analytics and system implementation. With 6+ years of experience transforming raw data into meaningful stories across staffing, sales, and finance industries. I specialize in SQL, data modeling, and building dashboards that drive real business decisions.
I've always been drawn to finding patterns that nobody else sees. Now I'm expanding into software development, combining my data background with JavaScript to build interactive data products that are as powerful as they are intuitive.
A mix of deep data expertise and growing development skills.
Data projects and web development work.
