Next.jsTypeScriptTailwind CSSReact
Designed and built an all-in-one browser-based developer toolkit with 300+ tools: JSON formatter, Base64 encoder, diff viewer, regex tester, color converter, UUID generator, and more. Zero backend — runs entirely in the browser.
The Challenge
Delivering 300+ tools with a sub-100ms LCP across all routes.
The Solution
Aggressive code splitting by tool category, dynamic imports for heavy parsers, and Tailwind v4 for zero-runtime CSS.
