Senior🎓
Top SchoolRoland Kosak is a Senior Software Engineer and architect with roughly 30 years of hands-on experience building everything from CAD/PDM and billing systems to mission-critical retail and large core-business SaaS products. Equally fluent on .NET and Java stacks, he has led architecture and delivery at companies like Visma, MFEX and RaySearch, often bridging product design, database modeling and build/configuration automation. He has repeatedly stepped into chief-architect and lead roles to drive next-generation platforms—bringing a pragmatic blend of SOA, messaging and ORM expertise to distributed systems. Based in Greater Stockholm, he pairs deep legacy-system knowledge (C++, Delphi, COM) with modern cloud-era practices, which helps him translate long-lived business domains into maintainable SaaS architectures. Colleagues value his ability to move between coding, modelling and team leadership, and his career shows a pattern of stabilizing complex core systems while enabling future evolution.
