Experience
- Hireology (Development)
Hireology was a major client of mine while working at OpenArc. At the time, I was the sole developer, working directly with the client to implement new features, improve payment flows with the Braintree API, and fix bugs.
- Web-starter-kit (Development)https://github.com/bmatcuk/web-starter-kit
Web-starter-kit is a simple example project that can be used as a good starting point for building a React web app using Webpack, including support for hot reload. The starter kit can build isomorphic apps where static pages can be pre-rendered, and all pages can be rendered server-side for improved SEO.
- Html-brunch-static (Development)https://github.com/bmatcuk/html-brunch-static
Brunch is a build tool for JavaScript and CSS that focuses on simplicity. Html-brunch-static is a plugin that adds support for building static HTML as well with pluggable support for several alternative languages such as Pug/Jade, Markdown, and Handlebars.
- Doublestar (Development)https://github.com/bmatcuk/doublestar
Doublestar is a drop-in replacement for Golang's built-in path Match and Glob functions that adds support for doublestars, a.k.a. globstars. For example: path/**/match would recursively match any file or directory called "match" under the "path" directory.
- Additional Code Samples on My Github (Development)https://github.com/bmatcuk
I have many open source projects available on GitHub in a variety of languages.
