A lot of website emissions come from the same things that make websites unnecessarily heavy: oversized images, unused scripts, excessive third-party tools and functionality that continues loading long after anyone has questioned whether it is still needed.
I can identify where those resources are coming from and help reduce, replace or remove them where doing so will not compromise important functionality.
That might mean better image formats, fewer requests, lighter templates, removing redundant plugins or reducing the amount of JavaScript and third-party code loaded on every page.
