Software Development Engineer III at Expedia Group
June 2018 - current

Worked in an organization responsible for the messaging tool for customer agents. This tool connects the customer with the agent. The tool provides a branded experience with the use of channels, allowing the customer to communication with chat, email, service requests, and a voice experience.

The team rebuilt the application using React on the front-end and Java/Kotlin on the back-end. I worked primarily on the front-end but communicated through technical and product teams.

  • Branded the Agent Messaging Tool: the project took the existing styling and converted it to our branded UITK framework.
  • Agent Messaging Tool: Worked on various features, one of the larger features being a tool to protect PCI information while the agent enters protected customer information. This was a complex interaction between multiple back-end system
  • Virtual Agent API Server: Worked on a Kotlin API server. Created an asynchronous endpoint to change the state of the conversation, from reserved to released. As it was a new server setup/implemented basic server functionality, such as retries, circuit breaker, haystack id, and others.
  • Rich Card Server: Created a server for a new "technology" called rich-cards, this server/repository with build process. This repository is used by multiple projects and requires the building of certain resources, the packages and branded CSS files
  • Outbound voice: this project enabled agents to place a softphone call from the agent messaging tool.
