ABOUT ME
Data analyst with 8 years experience in startups and big corporations
Data analyst with 8 years experience in startups and big corporations
Welcome! I have seen it all from fast-paced startups to working full time for T-Mobile and Microsoft. I'm "fluent" in coding and have used many different languages to deliver analytical insights to customers, co-workers, and executive leadership. I've been an algebra and calculus tutor since high school, trained in college to communicate concepts in an engaging and holistic way. Tutors (and new interns!) have always thanked me for my thoughtful and effective teaching style. Hope to hear from you!

I used D3 for all my interactive visuals. At T-Mobile I used D3 as an interface for Mapbox, Leaflet, and Carto geospatial maps. I understand the steep learning curve required to use D3, and I've worked hard to make it as accessible as possible

Steffan was great. I was stuck w/ a Dash issue, and he helped not only get me unstuck but he showed me a reusable workflow to prevent the issue in the future. He will definitely be my go-to guy for all things Python!

Joined this startup as their only analyst, helping to design a new fiber-optic internet infrastructure for the San Juan Islands. Used python to build network models, GIS to plot these networks, and visualization libraries (Grafana, PowerBI) to build real-time reports. Success designing these systems lead to full time employment at T-Mobile.
