Welcome to Jemmy Mongi’s Blog

This blog is where I document practical lessons from building websites, leading delivery, and mentoring developers.

What will I write about?

The main topics include:

• building fast, maintainable websites;
• improving Core Web Vitals and Google PageSpeed;
• working with PHP, CodeIgniter, JavaScript, and REST APIs;
• project management and communication within engineering teams;
• lessons learned from real-world projects.

Why publish here?

I want every article to become a reusable reference for myself, my team, and other developers. Because the blog is part of this personal website, the reading experience remains fast, focused, and independent from external publishing platforms.

The next article will cover how to evaluate website performance—from reading a Lighthouse report to prioritizing the improvements with the greatest impact.
