  • Homrr (Development)

    Homrr is a project that I conceived and built from the ground up. Unsatisfied with commercially available options for an in-home weather display, I built my own and included other information as well.

    Built using Node and React-Redux, it's deployed on Heroku. It includes integrations with Open Weather Map, Facebook, Google Calendar, and Google Maps. The project also showcases my ability to create responsive web applications.

  • WordPress Gift Registry Plugin (Development)

    When my wife and I were getting married, we wanted an online registry where guests could give us money for gifts. I couldn't find anything that suited our needs, so I took the opportunity to create this plugin. It's been downloaded almost 5,000 times and is still active on more than 300 sites worldwide. Built using jQuery, HTML, CSS, PHP, and MySQL, it features an integration with PayPal.

  • Bank of America New Year's Eve Social Media Billboard #TSQ14 (Other amazing things)

    While at Wayin, I worked with our clients on behalf of BoA to bring social media directly to the heart of Times Square on NYE '14. Using a hashtag, Twitter users had the chance to get their picture featured on a 60ft billboard in midtown Manhattan. I was technical lead on this project and was responsible for making sure the experience worked end to end. Built on top of a custom CMS written in Backbone.js, it included CSS3 keyframe animations and required on-the-fly CSS adjustments. We built the entire experience in less than a week to meet a tight client deadline.

  • Consumer Portal for Online Conferencing Platform (Development)

    I integrated the customer’s proprietary billing and provisioning system with BigBlueButton---an open source conferencing platform---handling overall application design, architecture, security, technology, design, and operations. The system was built in ES6, Node, Express, React, Browserify, and Gulp, deployed in a proprietary cloud infrastructure; and secured using JWT.
