Jakub Rosiński
Senior Software Engineer in Test at Snowflake

Jakub Rosiński

First and foremost, a tester at heart and in spirit, with over 10 years of hands-on experience. Currently a QA Architect who remains closely involved in “real testing.” He has tested mobile applications and devices, CRM systems, applications supporting medical research, lottery systems, CPQ solutions, and banking systems. He conducts integration, system, and acceptance testing—both as part of formal acceptance processes and in support of clients. He works in and strongly believes in agile approaches, team trust, and self-organization—which proved effective, as he had the honor of being part of the team that won TestingCup 2019. He tests both automagically and manually, primarily in an exploratory way. In that order, he is a critic, an (accredited) trainer, and an ISTQB certificate holder; he also reviewed the Polish version of the FL 2018 syllabus. He became actively involved in the testing community several years ago and absolutely loves it. He is happy to attend meetups and conferences as a participant, but also enjoys speaking and sharing knowledge with others. He loves to question things constructively (and to have his own ideas questioned) and lives by the thoughtful #itdepends approach.
