Led end-to-end architecture and development of a high-traffic customer utility app, focusing on performance, security, and offline capabilities using Realm DB. Implemented feature flagging and A/B testing for safe incremental rollouts to 2M+ users. Championed a mono-repo strategy for a shared component library (TypeScript, Styled Components), reducing code duplication and accelerating feature delivery. Built native bridges in Swift and Kotlin to integrate with proprietary hardware APIs. Established CI/CD pipelines with GitHub Actions and Fastlane for automated builds, tests (Jest, Detox), and deployment to App Center, App Store, and Google Play. Mentored mid-level engineers and set best practices for state management with Redux Toolkit and asynchronous data handling. Implemented advanced animations and micro-interactions using Framer Motion and Lottie.

Key contributor to the Caesars Rewards app; architected features including secure in-app payments with Stripe and real-time notifications using Firebase. Integrated observability tools (Sentry, Datadog) to monitor performance, reducing crash rate by 20%. Managed complex app state with Redux-Saga; built a GraphQL API layer aggregating data from multiple RESTful microservices to simplify client data-fetching. Optimized startup time with code-splitting and lazy loading (≈25% improvement). Implemented deep linking and push notification campaigns. Built automated deployment pipelines with Bitrise and ran unit (Jest) and E2E (Cypress) tests before production.

Developed a responsive web platform using React.js, Next.js (SSR), and Material UI, delivering a seamless UX across devices. Designed scalable backend microservices with .NET Core and Node.js (Express). Managed data with PostgreSQL and MongoDB, designing schemas for high-volume data. Leveraged AWS services (Lambda, S3, Cognito) and integrated headless CMSs (Contentful, Strapi) for dynamic content. Implemented forms with React Hook Form and Formik for validation.
