RESUME / PORTFOLIO FRAMING
Describe what you actually did.
Designed a feature-flag platform with targeting rules, low-latency evaluation, audit history and a client SDK.
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.
Streaming updates
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
Percentage rollout
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
Multi-region design
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
