I am Renzo Johnson, a full-stack software developer based in Orlando, Florida. I build WordPress plugins, WooCommerce stores, React interfaces, and native mobile apps. In short, if it runs on a screen, I can build it.
What I Build as a Full-Stack Software Developer
My primary focus is the WordPress ecosystem: performant software that solves real business problems.
- WordPress Plugins
Chimpmatic & friends
My most popular project connects Contact Form 7 submissions directly to Mailchimp audiences using the official API — merge field mapping, double opt-in, tagging, groups, and GDPR consent.
50,000+ active WordPress installations
- WooCommerce Stores
Storefronts that convert
Custom WooCommerce builds for clients who need more than a default theme. Every store prioritizes speed, accessibility, and clean code — storefronts that load fast and convert visitors into customers.
- React & Mobile
Dashboards & apps
React-based dashboards and admin interfaces for SaaS products — and I am expanding into native mobile development for iOS, macOS, and Android. The right tool on the right platform.
Technologies and Tools
My daily toolkit — everything from database schema design to pixel-perfect front-end implementation.
- PHP
- JavaScript
- TypeScript
- React
- MySQL
- Redis
- Nginx
- Docker
- WordPress REST API
- WP-CLI
- WooCommerce
How I Work
I am a Content Management System evangelist. However, I can build a static site for clients who require one. I offer the best balance of ease and control with WordPress, but I am skilled with a long list of CMSes to suit different needs. In particular, I focus on writing maintainable, standards-compliant code that other developers can pick up and extend.
Furthermore, I enjoy collaborating with smart people on challenging projects. I have traveled extensively to many parts of the world and revel in learning from different people and cultures. In fact, that curiosity drives how I approach every project — with fresh eyes and no assumptions.
When I am not concentrating on code, I work on Cnvrse, a live chat plugin that connects WordPress sites to Telegram, Slack, and Discord. I also enjoy photography, home mixology, and I write regularly about code, life, and things that make me happy.
Have a project in mind?
Most importantly, I care about shipping software that works reliably for real users. If you have a project that needs a developer who thinks beyond the code, I am available and ready to help.
