Bertold Kolics is a testing specialist with many years of experience working with engineering teams delivering commercial software. Practicing varied roles at software companies of all sizes during his career, Bertold developed a unique understanding that allows businesses to bring value to end users while satisfying customer expectations at the same time. He had the opportunity to work on legacy software projects, to improve projects inherited through acquisitions, and to bring greenfield projects to the market. Bertold enjoys collaborating in cross-functional groups with diverse backgrounds and constantly seeks ways that lead to high-performing teams. He also held management positions where he got to hone transformational leadership skills with open, honest communication that resonates well with team and business needs. Bertold has first-hand experience building, developing, and testing distributed software products created with languages such as JavaScript, Java, Go, and C/C++. Bertold currently works at Verosint, a small early-stage software startup that set out to help businesses detect and prevent online account fraud. As a sole software testing specialist, in addition to traditional quality assurance tasks, he works hard to enable his team to elevate software delivery practices. Modern testing principles guide his approach, where production data instead of gut feelings drive decisions. The sudden emergence of large-language models is forcing businesses - including Verosint - to embrace artificial intelligence in their offerings. Bertold had a chance to experiment with and develop testing strategies to guarantee expected outcomes in this new and unique realm that goes above and beyond traditional software testing practices.
