My name is Jordan, Iโ€™ve been designing, modeling, and creating products with Autodesk Fusion 360 for over 10 years specializing in prototype products and small scale manufacturing. During that time, I have developed an eye for design that is carefully shaped around the restrictions of real world production. Sometimes it can be difficult to bridge the gap between a designer and the reality of manufacturing, but my experience allows me to create an ideal compromise resulting in retaining the original design while ensuring the best result during production! Iโ€™m not only a designer, but a maker and business owner myself! ๐Ÿ› I have personal experience in small scale production (injection molding & 3D printing) ๐Ÿ’ธI understand the expense in starting a business ๐Ÿ’ฐI can work around any budget ๐Ÿ”ญI will help visualize your product ๐Ÿ”ฉI know how to design successful 3D printed items for cheap and rapid prototyping I can turn your vision into a reality. Give me a little guidance, some photos or drawings for inspiration and leave the rest up to me. Below are all of the file formats I can produce: - .F3D - .3MF - .IPT - .DWG - .DXF - .FBX - .IGES - .OBJ - .SAT - .SKP - .SMT - .STEP - .STL - .USDZ

Have an app idea but not sure where to start? A few years ago, I was sitting exactly where many of my clients are today: trying to turn an idea into an app. After years of mistakes and learning to code, I ended up building SchooLinks, which grew into an Inc. 5000 business and raised over $90 million. Book a consultation with me today! Iโ€™ll save you months of frustration by helping you understand the ins and outs of bringing an app to life: How much it costs, how long it takes, whatโ€™s the process and more. After launching SchooLinks, I now focus on designing and developing apps for: โ€ข Business owners looking to streamline workflows โ€ข Entrepreneurs looking to launch disrupting apps The apps Iโ€™ve built usually come in the form of: SaaS platforms, internal platforms, Mobile & web apps, Marketplace apps. And these are the results: โ€ข $350M+ raised by clients โ€ข 2M+ users across products built โ€ข 10K+ five-star reviews across products built โ€ข Top 1% in App Design & Development on Upwork Trusted By: Harvard, Samsung, Indeed, Yamaha, University of South Florida, and more. Technologies: OpenAI, Claude, Gemini, Flutter, Node.js, Angular, AWS, MongoDB, Figma If youโ€™re serious about building your app the right way, letโ€™s talk!

My web design work spans SaaS platforms, fintech dashboards, e-commerce, and mobile applications. Whether a client needs a complete product design overhaul or a focused UX audit, I bring the same structured, research-backed approach every time. Core UX/UI design services: product design strategy and UX architecture, complex wireframing and information hierarchy, rapid prototyping and interactive Figma components, design systems and UI libraries, user research and usability testing, heuristic analysis and CRO-focused UX audits, and creative direction including brand identity and visual language. Tools: Figma, Webflow, Sketch, Adobe XD, Illustrator, Photoshop, InVision, Axure, Hotjar, Mixpanel, Fullstory, Google Analytics, and UserTesting, Generative AI, Chat GPT, Nano banana, Claude, Gemini. โœ… ๐—ž๐—˜๐—ฌ ๐—”๐—–๐—›๐—œ๐—˜๐—ฉ๐—˜๐— ๐—˜๐—ก๐—ง๐—ฆ - 250+ UX/UI design projects completed with a consistent 5-star track record across the US, Europe, and Asia. - Recent highlights: a fintech core banking platform for Omniwire, simplifying complex issuer workflows into an intuitive product design across multiple markets. - A personal finance web application for MoolaX where the UX design reduced onboarding drop-off by restructuring information hierarchy and simplifying the dashboard UI. - A full product design and web design build for Austrian Audio, turning a high-end audio brand into a conversion-optimized e-commerce experience across desktop and mobile. โœ… ๐—ช๐—›๐—”๐—ง ๐—ฆ๐—˜๐—ง๐—ฆ ๐— ๐—ฌ ๐—จ๐—ซ/๐—จ๐—œ ๐—”๐—ฃ๐—”๐—ฅ๐—ง Most UX/UI designers are strong on research or strong on visuals. After 20 years across product design and creative direction, I bring both. Agency work trained me to design for persuasion and brand impact. Product design across 250+ projects taught me to design for clarity, retention, and real user behavior. The result is UX/UI work that looks considered, converts visitors, and gets built the way it was designed. โœ… ๐—–๐—ข๐—ฅ๐—˜ ๐—™๐—ข๐—–๐—จ๐—ฆ The clients I work best with are product teams and founders who need a UX/UI designer operating at both strategic and execution levels. I am equally comfortable running a UX audit, building a design system from scratch in Figma, or owning the full web design process from brief to handoff. My creative direction background means I think about brand, narrative, and conversion alongside usability.

I run a discovery phase covering user goals, business constraints, existing UX patterns, and competitive positioning. Wireframing and UX architecture come before any visual UI design decisions. This prevents the most expensive mistake in web design: building beautiful interfaces on top of broken user flows. I work in tight feedback cycles and deliver annotated Figma files with developer handoff specs, component documentation, and interaction notes so nothing gets lost between design and engineering. โœ… ๐—˜๐—ซ๐—ฃ๐—˜๐—ฅ๐—œ๐—˜๐—ก๐—–๐—˜ ๐—•๐—ฌ ๐—”๐—ฅ๐—˜๐—” SaaS and Fintech Product Design: Core product experiences for fintech platforms, banking dashboards, and data-heavy SaaS products where UX/UI design must make complex information readable and actionable. Every engagement starts with UX research and flow mapping in Figma before UI design begins. Web Design and E-commerce: Brand-led marketing sites, conversion-optimized landing pages, and full e-commerce UI including product pages, checkout flows, and mobile web. CRO principles and A/B testing applied wherever performance data is available. Mobile App and Responsive UX/UI: Mobile-first UX/UI for iOS and Android with gesture-based interaction design, scalable component systems, and design consistency from mobile to desktop.
