Hi! I'm Emruz Hossain. A senior backend and platform engineer with 8+ years of experience building distributed systems, Kubernetes platforms, and database infrastructure.
I design and build cloud-native backend systems, especially Kubernetes-based infrastructure and distributed services.
At Qdrant, I work on the Operator and Cloud Agent that run vector database workloads across cloud and hybrid-cloud Kubernetes environments.
I care about reliable operations, clear APIs, observability, and keeping complex systems understandable for both users and engineers.
> "Building cloud-native data platforms with user-focused operations."
Let's build something useful together.
