    Senior Web Developer

    United States - Last active: 1 day ago - Tests: 1 - Portfolio: 4

    15+ years' experience. I have a great set of long term clients. Expect complete honesty as that is how I have built my business. I am upfront about problems and solutions. I specialize in full enterprise level cloud applications as well as smaller website apps that are built to scale. I don't generally take on simple website design projects. I have built online affiliate programs, audio streaming technologies, Customer Relationship Management (CRM) systems, complex digital product creation tools, some of the world's most advanced online and cloud based design software, online training services, and several membership based websites with various back office tools and services. Scalable applications get me most excited. With everything I touch, I am concerned about how it will scale and how its technologies can live long term. I have extensive experience with browser compatibility, speed optimization, and UI and UX (user interface and user experience) work.
