I have a live business-portfolio website that feels sluggish and breaks layout on some devices. I need a seasoned developer to dive into the existing codebase, spot what is slowing us down, and return a site that is fully responsive and noticeably faster. Here is what I need from you: • Front-end design review and refactor – clean up the HTML5, CSS3 and JavaScript so every page adapts flawlessly from mobile to desktop, and reduce render-blocking resources. • Back-end functionality tuning – profile the current logic (Node/PHP, APIs, or whatever you find), streamline routes, add caching where sensible, and trim any redundant calls. • Database optimisation – analyse queries, add or adjust indexes, and fine-tune configuration to cut response times. • Concrete before-and-after metrics – Lighthouse or GTmetrix scores, server response times, and any profiling snapshots that prove the gains. • Final hand-off – updated code, a short change log, and quick notes on how to keep performance high going forward. You will have full access to the repo once we start. If you have questions about the stack, let me know and I’ll point you to the relevant parts of the project right away.
