Python software engineer building a recipe app that adjusts baking ingredients, temperature, and time for high altitude.

I’m building a Python app that looks up a user’s altitude and adjusts a baking recipe’s ingredient amounts, temperature, and time. I created a RecipeConverter class using Selenium and a Python unittest program to validate the measurement changes.

At Mantech International, I created a Bamboo CI/CD job to surface files containing bad data and authored a Python library that interacts with Elasticsearch. I also investigated differences between good and bad data and identified two features associated with the bad data.

At Elevi Associates, LLC, I created a Python library extending Selenium for automated web application testing and used SQLite3 to manage webpage elements and API paths. Earlier, I worked on data analysis and monitoring software at Everwatch Solutions, Clear Ridge Defense, and the United States Department of Defense.
