Profile bio

About Sean Williams

Sean Williams is a Information System Security Officer - CA2 at COLSA. He is proficient in English. Colleagues describe him as "To whom it may concern, Sean is one of the few amazingly intuitive test engineers I’ve known. He is unparalleled in his ability to find bugs in the products he is testing. He understands the products extremely well and is very intuitive. Sean has a deep understanding of the development cycle and fits in well with the development team. Sean was the most prolific bug submitter on the team and was only happy if he was finding bugs. As part of the QA team, it is sometimes difficult to have a good relationship with the developers – they don’t like to hear that you’ve found bugs in their code. Sean is extremely successful in developing those good relationships and working closely with developers. This extended beyond just the software team, but to the extended to R&D and even the Web development team as well. Part of the reason for Sean’s success, is his attitude. Sean has one of the brightest and congenial personalities of anyone I’ve met. He always looks on the bright side of things and puts a smile on your face – even when he’s telling you about the newest “issue” he’s found. His care for the product and for his teammates is clear. Sean the only person I know who can break the product and build a relationship at the same time. Any company who has him on their team is lucky to have such a dedicated QA professional on their team. Sincerely, William Mark Peter" and "Sean is one of the most conscientious, hard working people I have ever met. He attacks every task with zeal, and sees everything to conclusion. He is intelligent, funny, and an all-round great guy."
