Experience

  • Government App for Tracking Committees and Lobbyist Activity
    https://denver.maplight.com/public

    A .NET 5 and Angular web application for honesty and transparency in government-related funding groups. The project had three other development teams work on it before I got involved, so there was a lot of duplicate code and slow queries. I did a lot of refactoring to make the code more concise for accuracy and maintainability. Also, I wrote a lot of complex queries to get the correct data to the user. The project ended up being a success and was launched in May of 2022.

  • Geospatial Tracking App

    A .NET 6 and Apache Solr/Kafka application for tracking events and placemarks. I structured big data models and helped build a Solr search engine for geospatial data searches. I wrote APIs and pipelines to Solr for speedy results. I added Kafka queues to push out data and alerts to microservices in the system.

  • Cleaning Company CRM App
    https://www.cleanetto.com/

    A .NET/Angular 7 web application for cleaning companies to manage their business. I worked on the login and constructed the bearer token authentication with Angular. I added language translations and hooked up many pages throughout the project.
