- Supported back-end implementation of core services.
- Began as a back-end Java engineer to work on a multitude of Dropwizard microservices that communicate with a large Ruby on Rails monolith. Over time, the architecture has evolved, the monolith has become much smaller, and the need arose to form a common team of back-end engineers with skills to support both platforms.
- Contributed to the authentication and search domain teams.
- Led technical efforts for an external files project.
- Interviewed candidates.
- Contributed to a number of small (2- to 10-week) projects as a back-end developer with tasks also in front-end, infrastructure, and automated testing.
- Implemented Elasticsearch, Logstash, and Kibana frameworks to support all our service logging (application and system).
- Implemented support for external files.
- Redesigned data export functionality, replacing the old export stack and improving reliability.
- Made searching faster, improving the rendering of search results.
- Supported external group related features with Flexternal.
- Implemented rules for the access control library for accessing resources in Java (similar to the existing Ruby one).
- Monitored and intervened when alerts went off while providing on-call support.
- Developed a multitude of hacks, mostly around interactive bots, for hackday projects.
