Led a Trust Center guest-page performance initiative: raised the Lighthouse score from 31 to 55 (+77%), cut LCP from 40.9s to
11.7s (~71% faster), and reduced Total Blocking Time from 11.1s to 530ms (~95%) via Webpack chunk-splitting, hashed
filenames, and dependency tree-shaking.
● Cut startup JS transfer size by ~69% (1,267KB → 393KB) and unused startup bytes by ~42% (11.8MB → 6.8MB) by deferring
builder/editor features, lazy-loading MUI, dnd-kit, and remoteEntry.js (Module Federation) chunks, and removing legacy babelpolyfill.
● Improved perceived performance by deferring third-party scripts (reCAPTCHA, YouTube embeds) until after first paint and
introducing skeleton loaders and Suspense fallbacks in place of blank states.
● Strengthened code quality and maintainability by enforcing standardized ESLint rules, integrating SonarQube static analysis, and
refactoring legacy components.
● Drove extensive test coverage using Jest and React Testing Library, improving confidence in releases and reducing regressions in
critical UI flows.
● Architected and delivered a secure Document Management Platform supporting end-to-end CRUD operations, advanced
filtering, sorting, document sharing, and lifecycle management for enterprise users.
● Designed and implemented Role-Based Access Control (RBAC), NDA-restricted document access, and permission-driven
workflows, ensuring secure handling of sensitive business documents.
● Developed dynamic Guest and Sharer access frameworks, enabling controlled collaboration while maintaining strict security
and compliance requirements.
● Led resolution of critical production incidents, hotfix deployments.
