Yasin delivers excellent work. He is very proficient and knowledgeable with Keycloak and SSO standards. He makes sure to understand the requirements before implementing the work and will communicate profusely prior, during, and after implementation to keep you informed of the overall progress of the task. He is also very good at detecting edge cases and finding solutions to alleviate possible consequences. Finding great professionals on Upwork is not always easy, and I am very glad we found Yasin to help us with our projects. If you don't want to spend hours going back and forth getting your requirements understood, he is the person you are looking for.

I’m incredibly grateful to have Yasin on my side. His deep knowledge of Keycloak, from its early days to the latest updates, is unmatched. He’s patient, professional, and takes the time to uncover the real issues before offering thoughtful solutions. Working with him has been a game-changer for me and my customers—I couldn’t recommend him more.
