QA Automation Lead for the Dolby Atmos Music team. Created test automation infrastructure from scratch using Python/Py.Test. Designed a Python package that included a "Virtual MIDI Controller" for interacting with the Dolby DJ App. Added hooks into the app using C++ to help aid with the automation effort.Automated tests for long term playback, and regression testing. Created many automated tools for tasks such as backing up builds, parsing logs, and updating software on test machines.Was one of 2 lead engineers that installed Dolby Atmos into 4 venues worldwide, including nightclubs in Tokyo, London, Chicago and San Francisco. Utilized knowledge of audio networking, Dante and BSS and Xilica Processors to get the audio pipeline up in each club. Helped design the process to be more foolproof and scalable.Designed a log uploading and parsing website using Flask and Bootstrap. Deployed the site on a local server using Apache.

Developed and maintained pytest testing infrastructure for the Cinema Embedded and System Software group. The pytest regimen was utilized nightly in regression and stress testing scenarios. Worked with QA and Software Engineers to find and troubleshoot problems in Dolby's ShowStore systems (DSS100, DSS200, DSS220).Wrote automated tests against a web-based theater management program. Utilized knowledge in Selenium and Solr databases. Worked closely with developers to identify and address bugs as quickly as possible.Designed a web interface for system stress testing using Bootstrap, Flask, and Celery. The interface allowed users to kick off long-running tests from their web browsers and monitor progress and results.

Cupertino, California, Us

Senior capstoneWrote a program in python in a team of 5 that would analyze and display findings about manufacturing runs of the iPhone.Worked with a contact at the company to scope, design, and implement the finished product.Wrote a final report of the engineering methods, and presented to the client on site before delivery of the final software.

One of three programmers working on V Squared Labs’ Touchdesigner interface using Python. Used audio input data to create real time reactive visual effects that varied based on the characteristics of the wave and user controls.

Los Angeles, Us

Designed and implemented a C++ software tool that aided audio engineers in live 3D panning of a monaural sound source. The tool connected 3Dconnexion mouse with higher-order ambisonics (HOA) libraries.
