Site speed improvement expert wanted

I am looking for an expert to help me with speeding up my ecommerce website. Currently, the website is performing unacceptably slow, and I need someone to help with improving the coding quality. I require an individual with extensive knowledge and experience in optimizing website speed. The right candidate must be able to evaluate and propose recommendations that would improve the overall performance and user experience. They should have a strong understanding of optimization techniques, and be able to communicate effectively about technical matters. If you have the skills and experience I am looking for, I'd love to hear from you.
