  Intel, Hillsboro, OR
  Apr 2017 – Oct 2018
  Ethernet adapter validation was a key task in the project, involving the creation of test plans, conducting tests on network cards, and automating data analysis using Python and Excel. New waveform post-processing automation was written and implemented using Python, Jupyter Lab, and Pandas, which organized test data, produced waveforms, and analyzed them. This automation was capable of handling a large volume of data, generating over 1500 waveform figures from 1.7 billion+ rows of data. Additionally, Excel tasks were automated as part of the project.
