Brand Consultant & Creative Director 🏅 Expert-Vetted on Upwork (Top 1%) Helping startups, SaaS, AI companies and professional services build brands that are clear, consistent and ready to scale. I work as a strategic brand partner to founders and marketing teams who need more than just design. My role is to help define the brand direction, translate it into a strong identity, and apply it consistently as the business grows. Many collaborations start with a focused project and evolve into longer partnerships. I’m comfortable starting with a specific scope, as long as there’s room to understand the bigger picture and build something well structured. Think brand strategy first, not just design execution. Clear positioning, strong systems, and decisions that hold up over time. 🧠 My work focuses on • Brand positioning and messaging • Brand identity systems (beyond just a logo) • Brand evolution for growing companies • Guidelines and systems teams can actually use • Websites, pitch decks and key brand assets • Ongoing creative direction through retainers AI can accelerate exploration, but it cannot replace strategic thinking. I use AI selectively as part of the research and concept exploration process. However, brand strategy, positioning and identity development are always directed and crafted by me to ensure the brand is original, consistent and built for long-term growth. I don’t approach design as isolated tasks. I work best when strategy, identity and implementation are treated as a system. Clients often come with a specific need, and part of my role is helping them define what comes next. 🤝 Why clients work with me • I understand the business stage before designing • I bring structure where things feel scattered • I help teams make better decisions, faster • I think long-term, not just per deliverable 💬 Client feedback often highlights clarity, consistency and trust in decision-making “Estefania is a rare talent. She has exceptional design skills but much deeper, she understands branding and marrying these two disciplines. She completely reinvigorated our brand and throughout working with her, she prompted us to think deeper about what we represent, who we serve, and how we operate. We had a great experience and are totally thrilled with the end result. I wholly recommend her and look forward to working with her again.” — Anthony T. 📅 Currently available for one additional project in March 2026.

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.

Rooted in traditional graphic design, I specialize in product and web design with hands-on coding experience in HTML, CSS, and JavaScript. With nearly three decades of experience, I bring a comprehensive approach that balances creative vision, strategic thinking, and technical execution. Specialities: - Website design and development - UX/UI design for software and web applications - Corporate identity and branding - Editorial design Bio: After earning my BS in design in 1999 and working as a freelance graphic designer, I landed my first web-related role at a small web design agency. Back then there weren't dedicated web dev teams so designers usually had to code their own websites, there I learned HTML and CSS (an emerging technology) the hard way, dealing with the constant compatibility battles between IE6 and Netscape. In 2003, I co-founded a design agency with former design school colleagues. We started as a 5-person design shop and quickly grew to over 40 employees. Through our partnership with an engineering firm in Ukraine, we offered everything from graphic and web design to desktop applications and marketing campaigns. As art director, I led projects including UI design for desktop and web apps, and marketing campaigns for high-profile clients like Symantec and Vantage Software. After six years growing the agency, I was ready for a new challenge and joined MaestroConference, an Oakland-based company that provided technology for large-scale, interactive virtual events. Their client roster included the 2009 Obama Campaign, the White House, half a dozen US political entities (including 9 of the top 10 Democratic presidential campaigns), and non-political customers like the World Bank, Uber, and Airbnb. I worked as lead web designer, UI/UX designer, and eventually product manager alongside the CEO. In 2017, we launched VoiceVoice, a first-of-its-kind automated facilitation platform for large-scale virtual events, serving customers like Greenpeace and Women's March. I continued in my design and product management role until 2022, when the CEO sold the software. That same year, Folio3 contacted me to work on their most complex project to date: a 3D kitchen designer and budget planner application for one of Spain's largest kitchen furniture manufacturers. I served as product owner and designer for two years until the product launched in 2024.

Product Designer who takes messy, early-stage products and gives them structure — UX architecture, design systems, and interfaces people don't have to think about. 23 projects, 100% Job Success Score. I usually come in when a product has grown faster than its design — inconsistent UI, unclear flows, no system holding it together — and my job is to fix that without slowing the team down. Where I help most: • Turning early or unclear ideas into structured product flows • Design systems that keep things consistent as a product scales • UI/UX for web and mobile, wireframes through high-fidelity • Fixing usability and visual consistency in existing products I also lead a design department in my full-time role, so I'm used to thinking beyond a single screen — how a decision today affects the system six months from now. Clear communication, no disappearing mid-project, and I'll flag early on if something in the brief isn't going to work.
