Top SchoolKalab Oster is a Senior Software Engineer based in Portland, Oregon with 10+ years building production microservices, search platforms, and data pipelines across Java, TypeScript, Kotlin, Scala, Go and Python. He specializes in spec-driven development, semantic search/LLM integrations, and cloud-native deployments (Kubernetes, Terraform, ArgoCD) and has led small teams to ship greenfield services and replace legacy search with OpenSearch/LLM-powered platforms.
