About me

Alex Vall

I am a software architect focused on backend. I have experience in Microservices architectures developed in Java (Spring Framework - Boot, Cloud), Kotlin and kafka (async). I am always very focused on looking for open-source / infrastructure level solutions (Camunda for orchestration or OPA to handle authorization policies) rather than custom implementations. Any infrastructure level solution is usually better than a custom implementation. Remember !! People is first than processes !!
