    Custom WordPress Plugin and Theme development with Responsive design

    India - Last active: 18 days ago - Tests: 4 - Portfolio: 6

    Custom WordPress plugin and theme development is my specialty. I devote a lot of time to honing my craft so I can work quickly and efficiently to deliver bug free products to my clients. My expertise means I can deliver outstanding results, whatever the project. I am an expert at integrating remote systems and APIs with WordPress and creating custom content management workflows that fit what you need to accomplish. I also do frontend development including HTML, CSS and JavaScript and work obsessively to make sure that the output is correct in as many cases as possible. I try as hard as I possibly can to make my clients happy. Truthfully, there is nothing I want more than for both of us to walk away from a project with a great feeling of success. For me, that means I did good work and delivered on time and on budget. For you, it means you got exactly what you were expecting and nothing less. I really hope we can work together. I love the challenge of working on different projects with different clients all the time and I’m sure you’ll love working with me. I look forward to hearing from you! 24/7 Technical Support 100% Confidentiality Assured 100% Moneyback Guarantee

    Senior Web Developer

    United States - Last active: 6 days 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.
