For the last 3 years, I have been acting as the lead developer for the Built for Teams' application.

This application is built with Ruby on Rails, Backbone.js, Redis, and MySQL on AWS; it is tested continuously using RSpec and Capybara on Codeship. The app also uses AWS's S3, EC2, KMS, CloudFront, and others.

Last Advisor

Last Advisor is a retirement planning modeling solution for financial advisers.

I have helped maintain and improve this software for the several past years, and have more recently been tasked with rewriting, improving, and inventing new algorithms for the software.


Rizolv is a web-based software system that handles customer complaints for title companies.

Because much of the information provided by customers could potentially contain personally identifiable information, much of the data had to be encrypted at rest and in transit. The client also required that the application be written in ASP.NET so a teammate and I learned ASP.NET and C#, architected the n-tier architecture, implemented hardware encryption, and deployed the site to production—all in a little over 6 months.
