General Development & Methodologies:
Software Developer, Team Lead, Gaslight; Cincinnati, OH — July 2014 – Present
Customer software development focused on new product development. I was a Team Lead of small, agile teams of designers and developers who successfully delivered multiple projects to a diverse set of clients from Fortune 500 to startups.
- Used Ruby on Rails and Angular.js to build a complex auditing tool that enabled a Fortune 500 company to increase the speed and accuracy of their billing audits. I created an early prototype to prove the viability of this application that was thought to be “impossible” by some of the client’s team. The success of the project led to a follow-on project to customize the application for the sales team, dramatically improving the lead time of their sales quotes.
- Created a reporting API using Ruby on Rails that was utilized by multiple front-end Angular.js applications. The same backend was used to build applications that served both business and consumer markets enabling a very fast time-to-market and a short 3 month ROI on the consumer application development costs.
- Developed a complex, real-time data collection tool for sport statistics using Phoenix and Elixir. Utilized Web Sockets for real-time data synchronization across a team of people collecting data. This application used Phoenix, Elixir, Angular.js, and PostgreSQL. Enabled the business to collect a more diverse set of data, more accurately, in a shorter period of time than previous processes. The real-time nature will allow them to enter new markets for publishing that data.
Software Developer, Neo Innovation; Cincinnati, OH — Aug 2013 – June 2014
Customer software development focused on new products and Lean Software validation.
- Developed a highly scalable OAuth provider for a large telecom organization. This application provided authentication and authorization services for all of their public APIs. Built custom tools for concurrent load testing of the APIs under real-world scenarios using Go.
- Developed an e-commerce application for a unique, high-end fashion consignment startup. This application was built using Ruby on Rails and the Spree E-commerce engine. We created a highly-customized shopping experience for high-end clientele.
Owner / Software Developer, One-Line Fix LLC; Cincinnati, OH — Dec 2010 – Aug 2013
Worked with organizations to provide custom software development consulting services.
- Developed, designed and architected cash access systems. Implemented transaction processing host for an extensive network of ATMs, POS, and Kiosk devices. Included support for industry protocols and standards such as ISO8583, 91x, and IFX. Built scalable, core transaction system using Java 7, Netty, Spring, and JPA. Transaction acquiring occurred using multiple protocols all processed through a unified engine. Used Microsoft .NET technologies, including C# and WPF (XAML, Prism, MVVM), to build a rich-client application for initiation and retrieval of Credit Card, Debit Card and other cash transactions. Used Grails to create custom administration and reporting web applications to manage and monitor financial transaction processing.
