The most amazing...

...project I created was the internal web application for Braze, saving hundreds of hours of time, and money by automating processes.


  • Software Engineer

    2015 - 2018
    • Developed a web application for internal use using Ruby on Rails, React, MongoDB, and Memcached. I used Sidekiq, and Redis for message queueing, and JenkinsCI for running tests, and deploying the application. Papertrail, New Relic, and Sentry were used for error tracking, and debugging.
    • Developed a web application usage analytics UI. I recorded web application usage events in MongoDB, displayed charts of aggregations of user actions and page visits using React, and Highcharts.
    • Created an integration with SendGrid API for email account setup, domain authentication, IP warming, and IP pool setup. I built the UI using React for users to interact with the SendGrid API, display validations for domains, and download IP information.
    • Built Salesforce and Gainsight integration with the platform using Salesforce API, and AWS S3 buckets. I created daily cron jobs to send, and receive data between Salesforce, and Gainsight.
    • Created a Ruby style guide for developers. This prevented engineers from creating bugs, and reduced the time needed for review by automatically enforcing style rules using Rubocop.
    • Created UI for creating marketing campaigns and sending push notifications using Ruby on Rails, Mongo, and Knockout.js.
    Technologies: Ruby on Rails, React, Knockout.js, MongoDB, Redis, Memcached, GitHub, JenkinsCI, Papertrail, Sentry, New Relic
  • Software Engineer

    2014 - 2015
    • Built a calendar for fitness events using Backbone, and the FullCalendar.js library.
    • Developed a search bar using Elasticsearch for a social network site to search for users, and events. I created the back end with Rails, and PostgreSQL, and the front end with Backbone.js.
    • Built an Instagram integration to create social posts from Instagram posts. I used Instagram API, PostgreSQL, and Sidekiq to create posts asynchronously.
    • Developed iOS, and Android apps using Cordova, Ionic, and Angular. I used Ruby on Rails, and PostgreSQL for the back end, and storage.
    • Developed a video posting feature using Vimeo API, Backbone for the front end, and Ruby on Rails, and PostgreSQL for the back end, and storage.
