Hey everyone! I want to pick up a new backend technology stack and I’m thinking about using Kotlin together with Spring Boot. Since we’re halfway through 2025, I’m wondering if this combination is still worth learning. Will it help me get good jobs and stay relevant in the tech industry? I’m curious about whether companies are really using Kotlin for their new Spring Boot applications or if they mostly stick with Java. If anyone is working with Kotlin and Spring Boot right now, I’d love to hear your thoughts and experiences. Thanks for any advice you can share!
Used Kotlin with Spring Boot at my company last year - definitely worth learning. It plays nice with existing Java code, so teams can migrate gradually instead of rewriting everything. Lots of big companies are using Kotlin for new microservices while keeping Java for legacy stuff. Career-wise, knowing both languages puts you ahead since many teams are either using Kotlin or thinking about it. The cleaner syntax cuts our dev time by about 20%, especially for data classes and null safety. Demand’s growing fast, particularly in fintech and e-commerce where Spring Boot is everywhere.
interesting timing! why kotlin over java? coming from android dev or just like the language features? what’s your backend experience like? might help peeps give better advice 
kotlin + spring boot is a great combo! been using it for 8 months and it’s really smooth. we switched from java and for sure saw a boost in productivity with less boilerplate stuff. kotlin is gettin a lot of love, but java’s still king for job posts. so maybe learn both?
