Contract evolution without breaking callers

Backend-specific screens reward gRPC or OpenAPI changes you shepherded: additive fields, deprecation windows, dual-write periods, and consumer version skew. Name the clients that depended on the contract and how you proved compatibility.

Generalist resumes often stop at "built APIs." Backend hiring managers want the migration story — shadow reads, canary consumers, and how you rolled back a bad payload.

Keep React and CSS out of this section entirely. If a posting mixes full-stack work, put UI elsewhere; this page is for service-boundary ownership.

Consumer lag, backpressure, and hot-path latency

Queue and latency language is a backend differentiator: Kafka lag alerts, dead-letter handling, Redis hot-key mitigation, Postgres EXPLAIN wins, and p99 budgets tied to a named service.

If you only watched a platform dashboard, do not claim ownership. Write the before/after number and the tool that proved it — OpenTelemetry traces, a load harness, or production Datadog monitors you tuned.

Avoid cloud laundry lists. One OLTP store plus one queue plus one cache you operated beats a catalog copied from a job description.

Schema change safety and pager reality

Backend postings also screen for migration discipline: expand/contract patterns, lock awareness, online DDL, and runbooks linked from alerts. Pair those terms with the datastore you actually changed under traffic.

On-call keywords help when you were primary for the service — error budget burn, incident write-ups, and ownership rotation — not when you shadowed once.

HireConcierge can align API vocabulary to a posting from your experience; it will not invent a Kafka consumer fleet you never ran.
