Context
A customer loyalty platform served multiple business units with frequent change demand.
Problem
Deployments were fragile and production parity gaps introduced late surprises.
What I changed
- Added pre-release contract and migration checks.
- Simplified service boundaries around critical transaction paths.
- Built operational dashboards focused on failure modes and business impact.
Result
- Lower release rollback rate.
- Better predictability in delivery windows.
- Improved confidence for production changes.
Stack
PostgreSQL, Node.js services, CI/CD pipelines, Grafana.
Notes
Reducing unknowns before release had a larger impact than increasing deployment frequency.
