• Write and maintain unit testsacross the API, business, and data layers, and use the benchmark projects tocatch performance regressions.
• Support the Angular clientwhere it consumes the GraphQL API, and keep the schema and client contract insync.
• Contribute to worker scheduledtasks where API and background work overlap.
• Document graph types, queries,and the Oracle-side dependencies each surface relies on.
• Participate in code review, theweekly integration sync, and discovery sessions, and coordinate early with theCorridor / Aviate parity teams so we do not build the same capability two ways.
