Coding Playground
This simple integrated development environment (IDE) web application lets UI developers write HTML, CSS, and JavaScript to create simple designs. The idea is that a developer can quickly write some code and share it with other developers. This is an open-source project that's still under development.

A large multinetwork site for an HVAC company was originally hosted on a proprietary CMS, which we later recreated for WordPress. I created not only the theme but also a plugin that displays each site or branch on a map along with what areas a certain branch or site may cover and offer its services to.

Wink Browser Extension

A browser extension created and used for capturing screenshots and then editing them in an inbuilt image editor, integrated with a back-end service using JWT tokens to store images online on the cloud.

Wink Service

A companion back-end API first service for the Wink Browser Extension. This back-end service authenticates users, accepts images from the extension, and stores them.

The service also lets authenticated users manage image files into albums like a modern file system.
