A closer look at the products, systems, integrations, and engineering problems I've worked on.

Overview

Modernized the application's frontend architecture while gradually moving a large existing codebase toward modern React patterns.

What I Worked On

  • Migrated the application from React 16 to React 18.
  • Migrated class components to functional components and hooks.
  • Upgraded React ecosystem dependencies.
  • Introduced React Query for server-state management and caching.
  • Implemented lazy loading and code splitting.
  • Reduced frontend bundle/static asset overhead by moving images and static files to S3.
  • Added Error Boundaries at both component and application levels.
  • Managed compatibility between legacy and newer dependencies where required, including supporting different Bootstrap versions during the migration.

Overview

A shared workspace designed to bring buyers and sellers together throughout the sales process. Users can share and review relevant content and complete agreements through integrated e-signatures.

What I Worked On

  • Designed the frontend architecture.
  • Built the experience using React, TypeScript, and Next.js.
  • Used Redux and Context for state management.
  • Built content and asset rendering experiences.
  • Implemented responsive and mobile-first UI.
  • Implemented gated content and authentication.
  • Implemented page-based navigation.
  • Integrated the experience with Next.js SSR.

Engineering

A key architectural challenge was supporting authentication and gated content during SSR.

Browser-only authentication data stored in localStorage was not available during server-side rendering. The authentication/gating information therefore needed to be made available to the server through cookies so that protected content could be handled correctly before the page was rendered.

Next.js SSR was also used to fetch content-heavy APIs on the server before the page was delivered to the browser.

What I Worked On

  • Set up the frontend i18n architecture using i18next.
  • Implemented language switching and locale selection.
  • Went through application pages and extracted UI content into translation JSON files.
  • Organized translations by language for i18next.
  • Made new features localization-ready by following a translation-key based approach.
