RESUME / PORTFOLIO FRAMING
Describe what you actually did.
Built a background job system with concurrent workers, retry policies, scheduling and observable failure handling.
Use this as a starting structure, then replace it with your real implementation details, metrics and constraints. Do not claim outcomes you did not measure.
STRETCH GOALS
Go deeper if the core is already solid.
