.Net Senior Applications Developer, Angular Lead
Projects: i-Parcel EGOS, Find Parcels, Dashboard, Desktop App, DAO Micro Service, ZPL to PDF Label Preview, FTP Forwarder, DWS Console App, Branded Visibility, Smart Basket, Email Alerts, Routing Rules

Senior Software Developer
Projects: External Services, Rules Engine, PowerShell Deployment Tool, Cache Service, Cart
Tech: C#, ASP.NET, IIS, SQL Server, WCF, .Net, MVC, RAZOR, AppFabric, Entity Framework, CODE Framework, PowerShell, Bootstrap, TPL
  • Designed a software engine that calls external web services asynchronously to cut down the time waiting for a loan to the time that it takes the slowest service to respond. The final design separates “the engine” from “the processor” web service so that a new junior developer can code a new web service that participates in the decision-making process while isolated from the orchestration.
  • Automated the deployment of multiple web services to all the web servers in a cluster writing PowerShell scripts. The scripts launch a XAML GUI to collect parameters, then pulls the source from TFS, builds the projects with build configurations, configures destination IIS applications, and deploys to the servers.
  • Sketched out a new system to orchestrate web service call hierarchies and automate the deployment of web services, which reduced the time that it took on the website to get a loan approval from minutes to seconds, reduced the web service deployment time from hours to minutes, and re-architected the application from a monolith to an efficient service-oriented application which enabled the business to work on new mobile applications
  • Researched AppFabric, designed and built the cache service used by the Rules Engine
  • Built a dynamic business rules engine that lets the business define the business rules per region based on static and dynamic data points that determine the rule outcome. The business operates 450 stores across 9 regions covering most states.
