Most recently, I've been working at LendingHome (www.lendinghome.com), creating a mortgage investment marketplace. I work extensively on (and was a part of originally architecting) our internal credit policy system which describes all of the work that our salespeople and loan processors have to do in order to correctly originate and close a loan. This system is completely configurable and versioned so that we can re-use it across different loan products. I've also worked on integrations with multiple third party vendors, including Blockscore, Credco, Twilio, Black Knight, Clear Capital and Salesforce. I've mostly used Ruby on Rails, with a little bit of React thrown in. Additionally, I helped out the data team with a couple of projects & am familiar with configuring & writing YAML for Looker (a business analytics solution).
I also co-authored our internal A/B testing framework which allows us to place experiment configuration in the database (rather than in a flat-file) so that analytics consumers can build reports with no codebase knowledge.
My last project was automating the TILA-RESPA Integrated Disclosure (TRID) rules - an complex system of regulations dictating how and when LendingHome can notify borrowers of fee changes.
Previously, I worked at Amicus (www.amicushq.com) making tools to help non-profits and political campaigns mobilize their supporters. I spent significant time hacking on their calling tool (https://demo.amicushq.com/current_initiative/calls) as well as creating the first version of their postcards tool (https://demo.amicushq.com/postcards). I also helped to enable a data-driven culture by integrating InfluxDB into our homegrown dashboards built with NVD3 (http://nvd3.org/). All of Amicus's tools were made using Backbone and Rails; I am very comfortable going up and down the stack to complete features autonomously.
