Key Strengths

• Shipped and maintained a full-stack Next.js/TypeScript app on GCP (frontend + Flask middleware + cloud ops)
• Designed API layer integrating Flask middleware with a FHIR client for CRUD against a hospital FHIR server
• Implemented patient-provider messaging workflow using FHIR Communication resources
• Pragmatic state-management decision-making (chose Zustand over Redux for team fit and maintainability; addressed hydration issues)
• Improved UX reliability by implementing explicit async UI states (idle/pending/success/error) with progress + snackbar feedback, eliminating crashes/blank screens
• Strong testing discipline: built a 150-test Postman suite using partition testing for complex CRUD/nested-object rules
• Created extensive API documentation (30-page spec with operations and response codes) to ensure long-term consistency
• Production-quality CI/CD and test automation (GitHub Actions matrix testing with Android emulator across devices/API levels)
• Feature ownership/leadership: led Wikimedia Android 'Year in Review' feature end-to-end including planning, milestones, and cross-functional collaboration
