I was following the crypto industry trends all this time and started casually trading in 2021. In 2022 I had this idea to create a website that would feature all the most essential and useful tools/calculators that crypto traders and investors use on a daily basis. So I learned to code and created it myself, please be sure to check out the website in my portfolio in order to understand more about my frontend development skills, the quality of the products I create, and their extremely fast performance achieved thanks to Next.js.

Being especially passionate about real-time crypto analytics, I know where to get the right APIs that will provide you the access to trustworthy live data, whether you opt for free or paid APIs. I can easily integrate these data into your app using either raw data provided by the API or manipulating it in order to create custom analytics for your business and visualize it in your interface the way you want. Apart from all of this, my almost 10 years long experience in crypto gives me a profound understanding of the industry upcoming and current technologies, visual trends, and user expectations on functionality and UI/UX implementations. Have a great day, Alex

Your product has real potential. The problem is that it’s hard to use, hard to scale, or no longer reflects the quality of what you’ve built. That’s where I come in. I’m Mariano, a Senior UI/UX and Product Designer with 15+ years of experience designing digital products from the ground up. I specialize in turning complex ideas into clear, scalable SaaS platforms, dashboards, and mobile apps that are easy to use and built to grow.

I help make products clearer, more consistent, and easier to ship. What I help design: - SaaS platforms and internal tools - Data-heavy dashboards and analytics interfaces - Mobile apps for iOS and Android - Design systems that scale with your product - UX/UI redesigns for products that have outgrown their original design How I work: Every project starts with understanding the why: who the users are, what they need to do, and where the experience is breaking down. From there, I move through structure, flows, wireframes, and polished UI — always balancing usability, clarity, and visual quality. My handoff files are clean, organized, and built for real collaboration with developers. The result I’m most proud of?
