My existing MERN-based website is functionally complete, but its performance is falling short. I’m looking for a full-stack developer who can dig into the current React front-end, Node/Express back-end, and MongoDB layer to make the whole experience feel snappy. The main goals are clear: • Cut page-load times so initial content appears almost instantly. • Reduce server response time by streamlining API calls, query design, and middleware. • Polish the user interface so interactions feel immediate and fluid. What you’ll actually do: – Profile both client and server using tools such as Lighthouse, Chrome DevTools, and New Relic (or similar). – Refactor bulky React components, optimise bundle size with smarter Webpack configuration and code-splitting. – Implement caching, database indexing, and concise REST logic to trim latency. – Tweak critical rendering paths, image handling, and asset compression for faster first paint. – Hand back a concise report that documents every change, the before/after metrics, and suggestions for any future upgrades. I’ve kept the scope intentionally focused on performance optimisation only—no new features or design overhauls right now—so you can concentrate on measurable speed gains. If this sounds like your kind of challenge, let’s talk timelines and get started.
