Mar 2018 - Nov 2018
At TINYpulse I worked across our Product, Marketing and Customer Success teams to help drive analytical insights in a number of capacities. I was responsible for defining and tracking KPIs and other metrics across departments. I pulled and combined data from a variety of our service's APIs, Google Analytics, and our internal databases to automate the generation of reports and dashboards using MySQL, Python, RShiny and Tableau. I also partnered with product owners to measure the effect of user tests and experiments on product usage.I was also responsible for diving into our product usage data and identifying areas of improvement. I've developed predictive models for estimating company health and customer churn and used this data to inform our Customer Success team's outreach methods. I have also worked to develop machine learning models to identify high-performing employees and attrition risks among our customer's data.

Mar 2017 - Mar 2018
Worked as a cross-cutting analyst with the Geospatial Team helping several teams of researchers model a range of geospatial health indicators on a 5x5km scale. I developed ETL pipelines using Python and R to load, clean and merge large datasets for input into our models. I was also responsible for creating data visualization tools and dashboards using R Shiny for evaluating both our model inputs and results and detecting anomalies.

Sep 2013 - Sep 2016
At UW, I worked with a team of researchers in the department of Oceanography on a project dedicated to studying Carbon fluxes from large rivers. As a part of this team, I was responsible for cleaning, filtering and merging data from multiple environmental data sets using Python and SQL. I developed statistical models to help predict river fluxes using Python and R statistical packages. I generated maps and data visualizations for public dissemination as well as articles for scientific publication.
