Hi, I'm Prabhash 👋

Senior Software Engineer at Zalando, Berlin. I build backend systems, mostly in Java, and these days the part that helps parcels find their humans. On the side I contribute to open source, write about Java, and build small AI tools for developers.

Things I've built or contributed to

Older experiments

gRPC (4 API types, OAuth2, field masks) · Spring Authorization Server · GraphQL with Spring · HTTP/1.1 vs HTTP/2 benchmark · multi-region GKE with Terraform · KEDA + SQS autoscaling · Quarkus and Spring Native · testing with TDD, BDD/Cucumber, MockMvc, WireMock and Testcontainers

I also write sometimes

21 articles on Medium (gRPC, OAuth2, OpenTelemetry, HTTP/2, Quarkus, TDD/BDD, AI & LLMs for software engineers), Java articles for Baeldung, and the odd post on dev.to (latest: The WAV header is not 44 bytes). Latest three:
