    Full-stack AngularJS & Microsoft .NET Developer/Designer

    United States - Portfolio: 4

    I've been successfully delivering enterprise-grade .NET web software for over a decade for such clients as AT&T, Hilton, LG, Chicago Public Radio, Visalus Science, Sparrow Healthcare, Oceaneering -- and even helped briefly on BarackObama.com! Recently, my performance at 1218 App Team on a highly aggressive deadline for a complex medical industry project helped the team deliver on-time and secure a larger budget and significant follow-up work. That project involved daily 9am video scrums stand-ups, tight weekly Agile sprints, a cutting-edge responsive HTML5 canvas-based AngularJS front-end and a Websockets/SignalR Hub/RESTful API back-end, authenticating with bearer tokens via OWIN middleware. As a full-stack developer, I can handle a sizeable-budget project independently as well as work efficiently with both on-location and remote teams. I have years of experience working directly with clients, both domestic and international. Currently, I am tidying-up after migrating all my client sites to AngularJS and over-hauling http://sunshine-properties.com – and am available for projects and opportunities.
