As a freelancer, I have been working with Spring Boot and Spring Security for over 19 years. IT Surmann LLC provides specialized Spring Boot and Spring Security consulting and development services, personally delivered by me, Thomas Surmann. As the founder of Bootify.io, I wrote a tool for creating complex Spring Security setups directly in the browser.
I would be very glad to share my in-depth knowledge for specific Spring Boot and Spring Security challenges. If you need a freelancer / Freiberufler with a hands-on mentality, please get in touch. In case I'm not available, I will be happy to pass on your request to my network.
