- Refactored a 5,000+-line service into an abstract-class hierarchy, enabling existing and new workflows to share core logic via independent extensions — improving maintainability and establishing a scalable pattern for future features.
- Built a greenfield OEM partner-system integration end-to-end — OAuth2 with token caching, REST payload construction, duplicate handling, retry/alerting — architected as a polymorphic subclass of a multi-partner dispatcher for scalable onboarding.
- Optimized a high-traffic CRM search path by replacing per-result queries with a single batched, case-insensitive SQL query, eliminating an N+1 bottleneck and fixing a silent duplicate-customer bug.
- Coordinated a multi-phase feature with a cross-timezone international team against a tight deadline — broke work into four tasks, aligned stakeholders, and adapted to a new stack (Rails, Vue) within one sprint.
- Introduced cross-feature-flag validation that makes invalid configuration states unrepresentable at save time; shipped every feature with 300+ lines of unit/integration tests covering edge cases and error paths.
