Featured Case Studies

A selection of front-end and UI projects from web publishing platforms, focused on measurable performance, workflow, and consistency improvements.

Core Web Vitals Overhaul for a High-Traffic Publishing Platform

Problem

The flagship content platform was losing organic search visibility and readers on mobile due to slow, inconsistent page performance — Largest Contentful Paint regularly exceeded 4.5s and Cumulative Layout Shift flagged as “poor” on [70%] of article templates.

Role

Senior Front-End Developer — led the performance workstream, audited the rendering pipeline, and coordinated with editorial and ad-ops teams on trade-offs.

Tech stack

  • Next.js
  • React
  • TypeScript
  • Lighthouse CI
  • Cloudflare CDN

Measurable impact

  • Cut median LCP from [4.6s] to [2.1s] across the top [20] highest-traffic templates.
  • Reduced CLS-flagged pages from [70%] to [under 5%] by reserving space for ads and embeds.
  • Contributed to a [15%] lift in organic search sessions within [2] months of rollout.

AI-Assisted Design System Rollout

Problem

Four product teams were independently rebuilding the same UI patterns (buttons, forms, article cards), leading to visual inconsistency and duplicated effort across the publishing suite.

Role

Senior Front-End Developer — designed the component API, built the initial library, and used AI-assisted tooling to accelerate documentation and migration.

Tech stack

  • React
  • TypeScript
  • Storybook
  • Tailwind CSS
  • Claude/Copilot for codegen

Measurable impact

  • Shipped [40+] production-ready components adopted by [4] teams within [1] quarter.
  • Used AI-assisted code generation to auto-draft component docs and migration codemods, cutting rollout time by roughly [35%].
  • Reduced duplicate UI code across repos by an estimated [60%], measured via static analysis.

Headless CMS Migration for Editorial Workflows

Problem

Editors were blocked by a rigid legacy CMS that required engineering support for basic layout changes, slowing time-to-publish for breaking news and campaign pages.

Role

Senior Front-End Developer — built the front-end integration layer, designed flexible content models with editorial stakeholders, and led the phased rollout.

Tech stack

  • Next.js
  • Contentful
  • GraphQL
  • TypeScript
  • Vercel

Measurable impact

  • Reduced average time-to-publish for campaign pages from [2 days] to [under 2 hours].
  • Enabled editors to self-serve [90%] of layout changes without engineering tickets.
  • Maintained zero-downtime migration across [12+] content verticals.
