Performance Testing

I am in need of a performance testing specialist for a web application. The main objective of the performance testing is to ensure stability under load. I do not have defined performance benchmarks or standards, so I am open to recommendations from professionals. I am looking for someone with experience carrying out performance testing on web applications, who can provide in-depth feedback and suggestions on how to solve any issues found. If you have the skills and expertise to help with this project, I would be delighted to hear from you!
