Jan T is a Software Test Engineer based in Düsseldorf with 13 years of hands-on experience building and validating complex telecom systems, currently supporting Huawei’s state-of-the-art Online Charging System with containerized deployments and 4G/5G integrations. A computer science graduate who finished his B.Sc. early, he combines strong technical testing skills—functional and non-functional regression—with customer-facing experience liaising with clients and headquarters to deliver timely results. His background includes live operations and support at Blizzard, where he honed multilingual communication and incident escalation under pressure during a major AAA launch. Curious and product-minded since childhood, Jan brings a maker’s mentality to quality assurance, enjoying new technologies and taking ownership of end-to-end system behavior. Outside work he channels his analytical focus into gaming and esports, an interest that informs his user-centric approach to testing.
