Data Analyst & CSV Specialist

Sarah has spent more than a decade wrangling spreadsheets, debugging CSV exports, and teaching teams how to make data work for them. She previously led data-quality initiatives at a fintech unicorn, where she reduced reporting errors by 40 percent through automated validation pipelines. When she is not optimizing queries or writing about data tooling, you will find her mentoring junior analysts at local bootcamps and speaking at data literacy meetups.
