    Prudent Developer ~ Fantastical Designer ~ UX Genius

    United States - Last active: 1 day ago - Tests: 12 - Portfolio: 11

    Based in America's northwest, I've focused my development and design career on solving uncommon problems and innovating existing solutions. I enjoy the challenge of coding a new web application or complex website. I also like creating user experiences that make sense and anyone can feel comfortable in using. It's kind of like an art project wrapped in a puzzle. :-) If I haven't told you already, I own a small development and design agency in Boise, Idaho called Pixel and Line. We have a few in-house employees with a broad variety of skill sets. Working with a team like this can really open me up to new ideas, new technologies, and new perspectives.

    Conversion Rate Optimization Consultant

    France - Last active: 1 month ago - Tests: 2 - Portfolio: 13

    I am a conversion rate optimization (CRO) consultant. I provide CRO advice, audits, page mockups, designs, landing pages, a/b tests, site development, in short any service that will help you increase your online revenue. After 3 years of research and client work, I have developed a structured approach to conversion optimization: the ReveNEW Methodology, a method crafted with only one objective in mind: increase / multiply your online revenue. Unlike most CRO professionals, I don’t focus on flashy / ineffective short-term results, instead I create permanent conversion uplifts on my clients' sites. Perfect fit if you have an e-commerce or lead generation site that is not converting as much as expected while you are spending a lot of money driving traffic to the site.
