Backend engineer
I build backend systems for payments and billing. Over seven years I have designed services in Go and Java, run them on Kubernetes in AWS, and kept them reliable at high traffic. Recent work: I led the migration of a monolithic billing service to event-driven services on Kafka, which cut invoice processing time from hours to minutes. I also wrote the on-call runbooks my team still uses. Stack: Go, Java, PostgreSQL, Kafka, Kubernetes, Terraform, AWS. I like small teams with clear ownership, code review as a teaching tool, and production systems with good observability. Open to senior backend roles, remote or in Chicago.
