Hire the Best UX Designers
in Argentina

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 work closely with founders, PMs, and developers across the full product design cycle — from discovery and flows to high-fidelity, developer-ready Figma files. I don’t just make screens look better. 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 — tokens, components, and documentation that keep products consistent as they scale - 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 breaks down. From there, I move through structure, flows, wireframes, and polished UI, always balancing usability, clarity, and visual quality. For products with an existing design system, I often start with an audit — catching inconsistencies, gaps, and naming issues before they multiply across the product. I also use AI-assisted workflows (Claude, Claude Code) to speed up documentation, QA, and prototyping — without cutting corners on design judgment. My handoff files are clean, organized, and built for real collaboration with developers. The result I’m most proud of? Shipping full products end-to-end, where every screen has a purpose, every decision supports the product as a whole, and the design system holds it all together as it grows.

I'm an experienced UI/UX designer focused on creating high converting landing pages, websites, web apps and mobile apps. I'm also an accomplished Logo/branding designer. My favorite design tool is Figma. I also can turn my designs into Wordpress (Elementor pro), Webflow, Framer or into clean, fast loading, responsive HTML/CSS. I’m a human designer who knows how to use AI tools to enhance design, copywriting, prototyping, and imagery when needed, so Lovable, Claude, Cursor, and similar tools are part of my stack when appropriate — always guided by real UI/UX and product design experience. I'm always online, weekends too, if you have a questions don't hesitate to contact me. I’m not part of any agency, and I don’t represent someone else’s work. If you see my profile boosted by upwork or my availability badge ON, it means I have time to dedicate to your project. (if you see many open projects in my profile, they are mostly completed, inactive projects but my clients haven't closed the contract yet) 

I have been working in the field of design for about 11 years focused in user and costumer experience. As Ui designer I've been leading severals projects, native iOS mobile app, CRM, and landing pages in a full time job that allowed me to learn how to equilibrate the business interests with the user's needs, manage communication between client, design team and dev team, so I want to try all that knowledge and take risk with new challenges as freelancer.
