Full design + dev projects starting at $10,000 USD. Welcome to my profile. I'm a Webflow Partner, helping my clients by delivering premium web design and Webflow development services. ⭐⭐⭐⭐⭐ Client Review: "When I saw all the amazing reviews that Mack has on Upwork my instinct was to wonder "what's the catch." Then I worked with him for a couple months on a site build and can tell you there is no catch. He's so well reviewed because he's so dang good at what he does. And he's patient and highly communicative. 100% recommend working with Mack!" --- I can take on the end to end process (discovery, design, build) or a portion of the project (e.g., if you have a ready design, I can build it for you in Webflow). My offers: ❇️ Web Design ❇️ Webflow Development ❇️ Web Design + Webflow Development ❇️ Spline 3D Models/Scene Integration in Webflow ❇️ Lottie Animation Integration in Webflow A little more about me: I am a UI designer, front-end web developer, and marketing director with over 12 years of experience.

I will help you build a website for your business that looks amazing and functions amazingly well. I leverage my experience to help position your website for success and scalability by: ✅ Positioning your brand with integrity and trust through thoughtful, research-backed, beautiful, and modern design ✅ Optimizing your website's foundations for search engines by creating semantically sound code and on-page SEO best practices ✅ Future proofing your website by writing intuitive CSS code and creating a style guide to keep you or your team organized ✅ Helping you strategize and implement the right lead capture tools on your site (and route those submissions to anything else in your business marketing suite such as a CRM) ✅ Making it easy for you or your team to scale content (such as a blog) by utilizing CMS My workflow is simple by design, and depending on the scope of your project, it may look something like this: 1. We begin any project with discovery in order for me to learn as much as I can about the business, its clients, and the scope of the project 2. We then shift focus to wireframing to get the lay of the land. The goal here isn't to be exhaustive but to make sure all the content is laid out and laid out properly. This creates the framework for the design 3. After the wireframing is complete we start designing in Figma, going through an iterative process in the early stages to land on a design that is effective in communicating your message and that is in line with your vision; once that's established, the design process is extrapolated onto the remaining pages of the website 4. We then shift over to Webflow to build the website, optimize it for smaller and larger screens, establish good on-page SEO best practices, and setup any hosting and DNS requirements in preparation for launch This is very much a collaborative process, giving you an opportunity to compel the outcome at every stage of the design and build process. I look forward to hearing from you!
