Developer in Marketing at The Victoria Clipper. I work with a golden team of marketing experts using Google Analytics, TagManager, and Optimize with custom data collection from web customer interactions, Qualtrics surveys, social media and market demographics resources to find insights and trends among our customer base. Over the course of my time with Clipper, we developed a system that grew to allow us to match every sales transaction back to an advertising dollar spent, a UX improvement, a baseball game, the weather, the traffic on NW 15th Ave where we ran that billboard, a pampered experience for an important influencer, or a social share on Instagram. Our Tableau dashboard showed us spikes of interest in certain travel dates, long before plans were finalized and bookings were being made. We were also able to track website errors and misbehavior in the booking funnel, allowing us to draw links between overlooked product configuration errors to an immediate dip in sales

"Begin today!" That's all the note said. There was no indication from where it came or who may have written it. Had it been meant for someone else? Meghan looked around the room, but nobody made eye contact back. For a brief moment, she thought it might be a message for her to follow her dreams, but ultimately decided it was easier to ignore it as she crumpled it up and threw it away.
