"Megan has been a joy to work with. Thorough, communicative, with a strong command of both the technical and analysis side of analytics. Megan not only understands the instrumentation needed to have sound analytics but also the business use cases to ensure she's surfacing what matters most to the business. I highly recommend Megan!"
Dave, VP, Cro Metrics
"Megan was fast, efficient, communicative, and very knowledgeable in the skills required for the job. She made the process easy, reached out when there were obstacles, and produced high-quality work. I've worked with a few other freelancers on similar projects — Megan was, by far, the best. She knows her stuff."
Jared, agency owner
"Killing it! Thanks for your strategic mind, comfortable positioning of 'this is kinda messy' and making the client understand and feel 100% supported. Little did they know what was under the hood, and you've done a great job piecing it out for them."
Jill, Senior Director, Zaelab (agency partner since 2023)
