QUERY: engineering_impact

SELECT area, outcome, implementation
FROM engineering_impact
WHERE evidence = 'shipped',
area outcome implementation
Configurable Deal Sheets Shifted routine tenant field and layout changes from hard-coded application paths to database-backed profiles Generic React renderer, server-side validation, and admin-managed schemas
Complexity reduction Removed a 965-line hard-coded frontend field map and consolidated tenant-specific form behavior Stable field registry and reusable configured controls
Tenant migration Migrated 148 configured fields across two baseline tenant schemas Deterministic EF Core migrations and JSON backfills
Historical safety Prevented later configuration changes from silently changing existing opportunities Immutable published revisions, editable drafts, exact revision pinning, and controlled upgrades
Calculation safety Preserved two code-controlled financial calculation paths during the configuration cutover Typed C# resolvers plus 90+ xUnit facts/theories and characterization coverage
Delivery controls Made tenant-specific releases safer and repeatable Azure feature flags, automated quality gates, and GitHub Actions

EXPLAIN ANALYZE — how I work

1. Reproduce the behavior before changing it, capture the boundary in a test.
2. Keep configurable product concerns separate from code-controlled business rules.
3. Make migrations deterministic, idempotent, and explicit about historical data.
4. Ship behind controlled rollout paths and automate the checks worth repeating.
