If you need a passionate, experienced data professional, look no further. I love math, statistics, and writing beautiful code. These three things meet in the world of data science, and that's where I live. Below is my resume in a nutshell.
Our Daily Strength
Designed and led a team to build an iPhone/Android app using React Native that has reached over a million people worldwide.
GPU Performance Project
Built and continuously refactored a Monte Carlo simulation algorithm with OpenMPI to reduce runtime from 720 hours to 90 minutes, a reduction of 99.86%.
The Science of Data
Designed, built, and launched a resource for aspiring data scientists and engineers. Open platform for data professionals to publish articles.
Consulted with a Fortune 100 company to architect and create a data migration plan from Salesforce into an on-prem application. Extensive architecture analysis and diagramming in AWS, and data modeling in Salesforce.
Consulted in data analysis and visualization at the biggest tire distribution and logistics company in the U.S. Used SQL, Snowflake data warehouse, and PowerBI, as well as visualization and data cleansing in Python. Created and presented powerful data stories to C-level execs to provide insights into supply chain, sales, and customer survey data.
View Company WebsiteMy jobs included leading/assisting with software projects, improving our team’s in-house software to maximize project pipeline efficiency, interfacing with/training clients, and collaborating with project management and design teams on web and marketing projects. I mainly focused on integrating frontend applications with backend API's using JavaScript, PHP, and Python.
View Company WebsiteI worked as a data engineer on a team with other engineers to design and build a sensitive data identification and redaction service for the Risk Tech line of business. We used extensive AWS tooling, Java, Jenkins, and other tools to complete the project.
View Program WebsiteMy job has been to fine tune the design and software of the website, mobile app, and any other digital media to create the perfect user experience. This app has been used by over 1 million unique visitors as of January 2019. It is available via the web at ourdailystrength.com, and on the iOS and Android platforms.

View Company WebsiteCMDA is an applied integrated science degree. It combines mathematics, statistics, and computer science to build a foundation for data science techniques. Data scientists “have better statistics skills than any software engineer, and better software engineering skills than any statistician.” This degree prepares us for that role. We’re not just learning to be analysts, we’re scientists.

Implemented a Monte Carlo simulation algorithm in C and OpenMPI to model the change in energy of a charged system. Initially built in Python, then C, then expanded to an OpemMP model and finally OpenMPI. Our final refactors of the project reduced the simulation runtime from 720 hours to 90 minutes, a reduction of 99.86%. Note: Unfortunately due to Virginia Tech code sharing policies I'm unable to share the codebase.
Socially Determined sponsored a data project competition that focused on analyzing social determinants to predict COVID-19 outcomes. This was still at the onset of the coronavirus pandemic, and our analysis focused on building SIR models of case numbers in Maryland. We modeled the number of cases in each county in Maryland using the data from Socially Determined and present our findings to a panel of judges.
Using the statistical programming language R, I analyzed a dataset of sales transactions for an online superstore. I performed exploratory data analysis and found a possible logistical area for improvement. Using unsupervised clustering methods I isolated the busiest times of the year and used location data to pinpoint the best locations for product distribution centers.
View Github RepoTogether with 3 of my classmates, our job was to create and present a full lecture on a difficult machine learning topic. Our topic was Tree Boosting Using Gradient Boost. We had to research, compile the content, and write the presentation using R Markdown. Included was an overview of the method in plain language, an overview of the underlying theory, and implementation and interpretation of R code and output. We received an A+ for this project and it was deemed by fellow classmates the best presentation of the class.
View Github RepoI participated in the CMDA Fall 2019 data competition in the advanced group. Our dataset was a collection of hospital rating survey results from around the U.S. over a period of time. Our goal was to try and find states with sub-average healthcare facilities and attempt to find out why they had bad ratings. We did not use many machine learning methods but did have to perform some computationally intensive data wrangling and joining.
View Github RepoI started a resource for aspiring data professionals and people who want to understand more about the world of data. This project is 100% my own idea and creation, and I designed and built the website from scratch. The articles so far are my own, but I would love to have others write for me! I created this to share my passion for data science and hopefully learn more along the way.
View WebsiteI follow my passion for the medical field by volunteering with my local rescue squad. I drive ambulances, assist with patient care as a certified EMT, and work as a team with other volunteers to serve our community.
