Client work

Web performance

Speed work on two production sites, 4korners.org and cansulta.com, reaching PageSpeed 95+. On 4korners.org I added a page cache and an image CDN that serves WebP at display size, removed an unused plugin, and fixed a 5 MB logo. The homepage went from 14 MB to 3 MB, and pages now answer in 0.1 to 0.2 s instead of 1.3 to 2.8 s.

About

I am Jose, a full-stack developer in Montreal and a LaSalle College graduate. I learned the craft by building real things and shipping them to real users: I am the sole technical owner of the software at a non-profit, where I run a member portal in production, and I keep building small tools and experiments with AI and developer tooling. I care as much about the decision behind the code as the code that runs. I aim for quality and real results, and I work in French, English, and Spanish.
