He never worked with Fortran. His current favorite is Go. Viktor's big passions are Microservices, Continuous Deployment, and Test-Driven Development (TDD). He often speaks at community gatherings and conferences. Viktor wrote Test-Driven Java Development by Packt Publishing, and The DevOps 2.0 Toolkit.
