Javascript / HTML / Jquery / Ajax / Bootstrap Expert Required

We require an experienced Javascript / HTML / Jquery / Bootstrap developer to analyse and suggest improvements for the front end of our web service. Our service has expanded over the last 12 months and some users are experiencing slow downs. We are concerned that there may be some poorly programmed jquery bubbling up and causing multiple ajax requests. Or script blocking. But, we are a bit stuck on diagnosing this.

We would like an expert to look at the Chrome console on a live site and to diagnose any issues.

The service is a CMS / vehicle shipping system.

Ideally, the best candidate will be based in the UK as the checks need to be made during high usage (ie. between 11am and 3pm GMT).

Kind Regards,

Jamie
