2013 - 2016
Senior Software Engineer
Contix
- Built an NLP pipeline using RabbitMQ, Ruby, and Java to ingest tweets in real time, perform entity recognition, and perform machine learning techniques to classify the tweets.
- Built a restful API and web app front-end using Ruby on Rails to display real-time news alerts using web sockets.
- Built a native Windows application (in C#) and a native Mac OS X application (using Objective-C) that used the API and web socket connections to display news in real time.
- Created a React app that was meant to replace both the web front-end and native apps (via Electron) reusing as much code as possible. The web front-end piece was completed, and the desktop piece was mostly done (I just needed to work in native notifications), but the company ran out of funding.

Web-starter-kit
https://github.com/bmatcuk/web-starter-kitWeb-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
https://github.com/bmatcuk/html-brunch-staticBrunch 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
https://github.com/bmatcuk/doublestarDoublestar 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
