Project History
Testing REST APIs for Apex Clearing
As the only SDET (software development engineer in test) in a team of five developers, I participated in software delivery processes. I managed to complete testing for Apex Clearing's account authentication, cash management, and trade posting systems for each milestone.
QA Lead at Jive Software
As the QA lead for a team of five or six developers, I managed the remote QA engineers in addition to verifying the features of the Jive's JavaScript APIs. I also acted as a liaison between the remote QA engineers and the local developers whenever the product issues arose and gave the remote QA engineers the testing directions.
Whitebox Testing for McAfee's Foundation Service
As the only whitebox QA engineer for a team of seven or eight developers, I quickly learned the internal implementation of McAfee's Foundation Service APIs and gave directions on blackbox testing. With the knowledge of the product codebase, I was able to guide the blackbox QA engineers to test the product's vulnerability.
