Hey everyone! I want to pick up a new backend technology stack and I’m thinking about going with Kotlin paired with Spring Boot. Since we’re halfway through 2025 now, I’m wondering if this combination is still worth investing time in. Will learning this help me land good jobs? Do employers actually hire developers who know Kotlin for Spring Boot work, or do most companies still prefer plain Java? I’m also curious about whether this tech stack will stay relevant in the coming years. If anyone here works with Kotlin and Spring Boot professionally, I’d love to hear your thoughts and experiences. Thanks for any advice you can share!
kotlin + spring boot is solid right now. we switched from java last yr and it’s been great - way less boilerplate and null safety catches tons of bugs. most companies still use java, but the ones on kotlin are usually the forward-thinking places you’d actually want to work for.
I’ve been working with Kotlin and Spring Boot for three years now, and this stack is definitely still relevant in 2025. Netflix, Pinterest, and tons of Fortune 500 companies are using Kotlin for backend work alongside their Java systems. The best part? You can slowly add Kotlin to existing Java codebases without any major migration headaches. Job-wise, there aren’t as many Kotlin positions as Java ones, but they typically pay better since fewer people have the skills. Spring Boot’s Kotlin support is fantastic - coroutines and extension functions give you real productivity gains over plain Java. If you already know Java, the learning curve isn’t bad, and you’ll end up with cleaner code that’s easier to maintain.
interesting timing! what drew you to this stack - kotlin’s recent momentum or something specific? why kotlin over scala or other jvm languages for backend?
