Hey, With over 9 years of experience in web development and a strong focus on performance tuning, I’ve tackled similar challenges using Google Lighthouse/PageSpeed Insights. For example, I recently reduced JavaScript execution time by 40% and improved LCP to under 2.8 seconds for a client’s e-commerce platform. For your project, I’d prioritize streamlining JavaScript and CSS, optimizing third-party integrations, and restructuring the DOM for better efficiency. Tools like lazy loading and critical CSS generation will be key to reducing load times while preserving design fidelity. A quick question: are there specific third-party scripts causing delays that you’d like preserved, or should we evaluate them all? Let’s discuss your goals further to ensure we hit the 85+ performance score target. I’m confident we can achieve great results together within your timeline. Looking forward to hearing your thoughts!
