Experience

JustInVoicIt

An invoicing software for freelancers. I built this simple monolithic Ruby on Rails application from scratch. I championed the philosophy that invoicing software should prioritize efficiency over unnecessary features that go unused.

Engineering Insights Analytical Tool

The website was built with a Ruby on Rails back end and a React front end to showcase engineering insights. It collects data from BigQuery, where information from 3rd-party sources like GitHub and Jira is loaded through Fivetran. It was designed for high modularity and scalability. This project allows new analytics metrics to be easily added at any time.
