Summary
Karol D is a software developer and solutions architect with 11 years of experience specializing in access control and identity management, and a parallel career as a Japanese-to-English translation specialist. He has deep Java backend experience from multi-year roles at Sabre Holdings, contributing to core airline and customer experience projects, and earlier security-focused work implementing simplified XACML SDKs at Axiomatics. Karol’s background also includes hands-on AI and game-mechanics development for open-source MMO projects, showing a breadth from systems security to real-time simulation. Based in the Cracow metropolitan area, he pairs a formal Computer Science education (M.Eng.) with studies in Japanese language and literature, enabling cross-cultural technical and translation work. Colleagues describe him as a pragmatic engineer who bridges complex protocol-driven systems and practical developer tooling. Unusually, he balances long-term industry roles with sustained volunteer translation work since 2013, reflecting both technical depth and disciplined multilingual collaboration.
