WPExpress
https://github.com/Page-Carbajal/WPExpressWPExpress is a WordPress framework for software developers that I started building to enhance my-own development experience while coding on WordPress.
WPExpress is a set of components that can be used together or apart to extend WordPress functionality and is 100% open source under the GPL license.

Headless WordPress Proof-of-concept
The client requested to build a new version of the website without creating any complicated code to improve the website's loading speed and beat Optimize Lighthouse time to Interactive.
To create a POC, I implemented a Next.js project based on TypeScript, and when using Puppeteer, I took a snapshot of the requested content and served it as raw HTML. Optimized scripts and styles and loaded them in the proper order.
The POC made the resulting website 2.3 times faster than the original. More optimizations could be made by making a single script service that returns all the functionality based on URL parameters and uses NextJ.js as the renderer.
Before being able to work on the project, I had to fix the client's infrastructure issues. There are several issues. The server is producing an enormous amount of error logs, so I was asked to create a script to remove the logs after a specific size. This was a hack to prevent the server from collapsing due to a lack of space. I also activated Varnish for caching.

WordPress WooCommerce Website Optimization and Migration to Shopify
This was a great project. I loved working with this company.
During the first year, I worked with a Toptal DevOps engineer to optimize and auto-scale WordPress and WooCommerce as far as these tools can go. I modernized much of the code to use the latest PHP Standard Recommendations (PSRs) and pushed it to use the latest version of PHP.
After a year, the company decided to migrate the website to Shopify. I built a Laravel API to make the integrations for third-party services like fulfillment and affiliate marketing, among others.
