Full-Stack MERN App Optimization
Budget: £20 – £250 GBP
Our production MERN application is stable but starting to feel sluggish and dated, so I want a full-cycle tune-up that touches both ends of the stack.
Frontend scope
React needs a sharper, faster UI. Using my Figma files as reference, refine the overall look and flow, squash the obvious bugs, and push bundle size and render speed down without breaking existing features. I expect meaningful Lighthouse gains and visibly smoother page transitions.
Backend scope
On the Node/Express side, new and revised APIs must slot in cleanly, queries against MongoDB need tightening, and server performance has to hold under heavier traffic. Hot paths should be profiled and refactored until response times noticeably drop.
Deliverables
• Updated React code with Figma-aligned UI/UX tweaks
• Verified bug fixes and performance metrics before vs. after
• New or refactored API endpoints with Swagger/OpenAPI notes
• Optimised MongoDB queries and server benchmarks
• Short hand-over document and clean Git commits
All work happens in our existing GitHub repo; please branch, PR, and document as you go so review is straightforward.
