Senior🎓
Top SchoolSerhii Diahovchenko is a seasoned full-stack software developer with 14 years of experience designing and delivering scalable PHP/JavaScript web systems, currently building backend and architecture at Hobbii in Copenhagen. He has deep expertise with Contao CMS—contributing bug fixes and core backend improvements to both contao/core and contao/contao—and a track record of integrating complex third-party services (MailChimp, Emarsys, multiple payment and logistics providers). Serhii combines hands-on coding, database optimization, and test-driven development (PHPUnit, Codeception) with practical system architecture from projects ranging from e-commerce platforms to custom APIs. Early experience in embedded ASM and Delphi for scientific instruments gives him an uncommon low-level perspective that informs robust, performant higher-level solutions. Colleagues rely on him to stabilize legacy systems while iterating quickly on new features across the full stack.
