Collaborated with the other engineers on:

▪ The VoiceOps frontend. A platform for call center managers and coaches to view the transcripts of their employee's calls, review labels about what happened on each call, and do live coaching via comments in the app.
▪ A mechanical turk-style transcription marketplace that supported 10k+ daily users logging in and performing manual transcription, transcript grading, and transcript tagging tasks.
▪ A data pipeline that transformed raw audio data into transcribed and tagged text.
▪ Multiple customer integrations that imported data from our customers into our data pipeline.

### Software Engineer @ Chatham Financial

The Platform Engineering team maintains and revamps the underlying architecture used by other development teams across Chatham. We work on things like our in-house REST API template, our document storage system, permissions API, etc.

▪ Implemented supplier-initiated SAML SSO for flagship website. Used internally and by multiple clients.
▪ Moved the cookie authentication and management from a C# legacy library to a .NET Core microservice that could be used by static web applications. Supported 10k+ requests/sec.
▪ Collaborated on changing our document storage solution from a file system storage system that needed to sync across all offices to a blob storage system that only synced between two offices for failover reasons. Used to store all internal documents and documents uploaded to our web offering by clients.

### Software Test Engineer @ Chatham Financial
Jan 2016 – Jan 2017 | Greater Philadelphia Area
Helped guide a small team of developers in creating the correct software for complex hedge accounting situations. Learned the hedge accounting system and constantly asked pointed questions to help guide the team’s thinking.

▪ Collaboratively lead a project to create an internal test dashboard that aggregated every software team's test results into a single platform. The platform allowed users to view their test results including screenshots of failed UI tests and re-run the tests, no matter the test runner, directly from the platform.
▪ Wrote automated acceptance/regression tests in C# and Ruby to confirm the software’s functionality daily.
