I have an existing e-commerce platform built with React.js and I’m ready to tighten things up so the shopping experience feels faster, cleaner, and more conversion-friendly. The core architecture is in place: React on the front end, a RESTful API feeding product data, and a payment gateway that already processes live orders. What’s missing is the polish that makes customers stay, browse, and check out without friction. Here’s what I need from you: review the current codebase, identify bottlenecks, and implement pragmatic improvements. That may include refactoring components for better state management, trimming bundle size, introducing code-splitting or lazy loading where it matters, and revisiting key screens—home, product detail, cart, and checkout—for a modern, intuitive interface. I’m open to suggestions on adding micro-features like smarter search, streamlined filtering, or an upgraded review module if you see quick wins. You’ll have GitLab access for branching and merge requests, a staging URL for live QA, and direct feedback from me as we iterate. Final deliverable is a clean pull request that passes existing tests, includes any new unit tests you add, and a concise changelog describing each improvement. If React hooks, context, Redux Toolkit (or your preferred lightweight alternative), Webpack optimization, and Lighthouse scores are second nature to you, let’s talk.
