I have over 12 years of experience as a QA Tester. I have tested in Desktop, Mobile and Tablet so I'm versed enough to understand how that works in all those cases. I've worked with JIRA pretty much my entire QA experience. I've also been an admin where I've managed projects in JIRA, so I know how workflows work, filters, boards, etc. I've mostly worked with SCRUM but I've had a 5 year experience with Kanban as well. I have experience leading teams, teaching college students and rookies, doing interviews and project management. I am a perfectionist, which means that for the work that I do, this helps me a lot in making sure bugs don't go through and are caught fast. I always try to deliver the best products because I am a difficult customer myself, everything must be working like they do on ships.
