I supervised Warner when he worked at BlackBerry as a Wireless Protocol Specialist intern. I can easily say he was one of the best interns I have worked with over the years. Warner is a quick learner and always did a thorough and complete job investigating any failures in the cellular protocol tests that were run every week. His reporting was clear and concise, and he always had the next step in mind. Warner certainly knows a lot about cellular protocols, and in addition, he did a great job scripting in Python to automate many of the test cases that our team runs. I was sincerely pleased when Warner joined our team as a full-timer after his internship. I have been working with him ever since and it has always been a pleasure.

I know Warner since his time as an intern in BlackBerry, 4 years ago. Warner is an extremely quick leaner and hard worker. Already during his intern term he showed that he has thought through a testing area and is coming up with own strategies to identify problems and their root causes. Since then Warner has grown to become one of the assets of the IOT team. Now he is very experienced in IOT testing and script writing. He has written many tools used for analysis of infield performance of one of our BB10 Z series products. Like a normal IOT tester he is doing carrier and vendor IOT testing but since BlackBerry is developing an own platform he is also creating own test series and is very inquisitively identifying areas of imperfection in the platform requiring improvement. His very deep involvement in the field performance log analysis is giving him the ideas for these tests. These areas would stay unnoticed in standard testing but they would often create a serious problem in the live network or be a performance issue to the least. Like that Warner is able to deliver a very significant contribution to the company’s success. At the same time the development of own test cases is allowing Warner to acquire a unique qualification. Warner’s involvement in the infield performance log analysis earned him a reputation beyond his immediate team and it became his task to report on certain aspects of the in field performance testing to the management. Warner has an excellent development potential and would be a testing expert or systems engineer no future employer would like to miss. Warner’s work on the creation and tuning of his test case suite supplied him with in-depth know-how in the complete range of 3GPP wireless standards such as GSM, EGPRS, UMTS, HSPA+, LTE FDD and LTE TDD. This detail know-how is reaching the level of some system engineers in the industry and will further promote his development in future.
