  • Performance Architecture: Engineered a performance-first architecture for the core learning platform (app.mobietrain.com), implementing advanced code-splitting and route-based lazy-loading that significantly reduced the initial JavaScript bundle size and improved First Contentful Paint (FCP) significantly for mobile-first users.
  • Interaction Design & Engineering: Spearheaded the integration of react-spring and Lottie to create high-performance, physics-based animations, enhancing the gamified learning experience without compromising browser main-thread stability.
  • Product Strategy & Design Systems: Partnered with the design team to translate complex UI/UX requirements into reusable, scalable React components, ensuring visual consistency and technical feasibility across both the learner app and the administrative CMS.
  • Quality Engineering: Led a strategic initiative to increase automated test coverage by 15% using [Jest/React Testing Library], implementing integration and unit tests that reduced production regressions and improved long-term codebase maintainability.
  • Full-Stack Integration: Managed complex data-fetching logic using GraphQL and Redux, architecting efficient state management patterns to handle localized content delivery via react-intl for a global user base.
  • Technical Ownership: Owned the technical lifecycle of quarterly feature objectives, from initial scoping and frontend architecture decisions to containerized deployment using Docker.
