About

WordPress Expert, Open Source Contributor & Founder of CODE TOT

My Story

My journey in web development began in 2015 when I started contributing to the WordPress ecosystem. What started as translation work for the Vietnamese community quickly grew into deep involvement with WordPress Core, meetup organizing, and eventually founding my own company.

In 2020, I founded CODE TOT JSC — a specialized web development agency focused on building fast, SEO-friendly WordPress websites. Today, CODE TOT employs a team of 10-49 people, serving clients with custom WordPress development, performance optimization, and WooCommerce solutions.

Beyond client work, I remain deeply committed to the WordPress open source community. Through the Five for the Future pledge, CODE TOT sponsors 4 hours per week across Community, Core, Core Performance, and Polyglots teams. I serve as a General Translation Editor for Vietnamese, ensuring WordPress and its ecosystem are accessible to Vietnamese-speaking users worldwide.

My Guiding Principles

Performance First

Every website should load fast. I target sub-2-second load times and 90+ PageSpeed scores. Speed is not an afterthought, it is the foundation.

Open Source Commitment

I believe in giving back. Contributing to WordPress Core and translating the ecosystem into Vietnamese is part of my mission. 70+ projects translated, 4 hours/week pledged.

Quality Over Quantity

From clean code to thoughtful design, I prioritize craftsmanship in everything I build. No page builders, no bloat, no shortcuts.

Continuous Learning

From PHP to Vue.js, Docker to DevOps. I'm always expanding my toolkit and sharing what I learn through blogging and community events.
