• Contributed to Domain Transfer v2 (Ruby on Rails, React), redesigned transfer flow from full-page to modal with eligibility checks, validation, and real-time status notifications; drove a 45% increase in successful transfers and 36% reduction in support tickets on peak traffic days.
• Built domain verification and notification infrastructure (automated suspended/verified emails, job-based delivery) with event instrumentation; validated via Observe and SQL that 93% of affected domains were verified within 24 hours of rollout resulting in a 99% reduction in support tickets.
• De-risked Yugabyte database migration by auditing schema integrity across 4+ table types, enforcing non-nullable primary keys, and authoring backfill tasks to normalize 20+ million rows ahead of cutover, eliminating a critical class of data integrity failures at production scale.
• Authored critical end-to-end tests across 5 core merchant-facing surfaces using React Testing Library, simulating real user interactions to validate creation flows and catch regressions across critical storefront functionality.
