Bertold Kolics is a testing specialist with many years of experience in commercial software engineering teams. Working in various roles at commercial software companies of all sizes during his career, Bertold developed a unique understanding that accelerates businesses delivering value while satisfying customer expectations at the same time. His relentless drive to get to the root cause of issues early in the career earned Bertold the nickname of bulldog engineer by none other than Intel’s current CTO. He had the opportunity to work on legacy software projects, projects inherited through acquisitions as well as first-version releases as well. 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 tuned to the needs of the team and the business. Bertold has first-hand experience building, developing and testing distributed software products created with languages such as JavaScript, Java, Go, C/C++ to name a few. The importance of code reviews during the software development process is a constant theme that followed him from project to project. Examples include a software application inherited through an acquisition with subpar quality as well as a telco-grade, highly-scalable middleware product servicing hundreds of thousands of operations per second. 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, he gets not only to practice traditional quality assurance tasks, but to enable his team to elevate software delivery practices. Modern testing principles guide his approach that highlight the importance of decisions based on production data as opposed to feelings or past experiences, and the software quality as seen through the eyes of the customer.
