Manage a team of developers to implement full stack software solutions using development best practices. Architect, design and implement solutions for healthcare management. • Designed and implemented an internal medical coding web application using AngularJS.• Set up a web build process using NPM, Gulp and Browserify.• Enforced team unit testing using NUnit for the back end and Karma and Jasmine for the front end.

Responsible for architecture, design and development of new products, improvement of legacy software, and helping the company progress towards long term technology solutions in healthcare analytics.• Implemented several analytic reports using Angular, Kendo UI, ASP.Net and T4 templates• Developed an admin interface for creating roles and permissions using Angular and ASP.Net• Architected and developed a scalable file import process using C# and RabbitMQ• Architected an analytics API using Microsoft Web API and C# backed by a Vertica cluster• Spent several months evaluating several analytics database engines, gathered metrics and made a recommendation to the company• Developed an AJAX based administrative web site using HTML, JQuery and Backbone.js• Developed a REST-based API in Java for external clients as well as internal applications to provision practices, users and related data• Improved and supported a GWT-based document imaging web application• Developed a desktop application using C# and WPF to submit electronic remittance files from clients• Transitioned the development team from Subversion to Git

Created enterprise solutions using C# and .NET technologies, including WPF, WCF and LINQ. * Developed a web service based document store including versioning, security and real time renditions between file types.* Architected and developed an application to allow users to identify documents types of scanned documents for purely electronic sorting and filing.

Worked as a primary developer on a new incentives platform built on Spring 2.5, Struts 2, and Hibernate 3. Responsible for architecture, design and implementation of several major components.• Integrated the platform to our existing rebate system. Designed a translation module that used an xml configuration and common interfaces to translate data objects between the two systems. Used remote EJB calls to perform business operations on the rebate system. Wrote a scheduled process to periodically pull and synchronize data between the two systems.• Helped implement a party hierarchy, with roles and complex relationships to represent users, organizations and contacts.• Designed a data encryption system that allowed for flexible changes in the type and method of encryption, encrypted data directly from the web layer and was portable so it could be used in other systems with minimal setup.• Developed several branded websites, including custom validation, searchable history and role based views.• Responsible for the design and implementation of a plugin framework that allowed customer reward amounts to be calculated on the fly. The framework used XML for plugin definitions and a Java framework that integrated with the main application.• Implemented a new way of storing and filtering customer communication messages to allow greater flexibility and reduce the complexity of reports. • Implemented a process that migrated promotions and submissions from a legacy system to our modern system with traceability and failure recovery.• Built a process that read data from our system and sent an XML data feed over an HTTP connection. Used JAXB to create the Java files and generate the resulting XML file.
