Brand Identity Designer & Strategist 🏅 Expert-Vetted on Upwork (Top 1%) Pitch decks, case study design, whitepapers & scalable brand systems Many projects start with a specific piece — a pitch deck, an investor presentation, a whitepaper or a branded editorial piece — and grow into full brand and system work over time. I help startups, SaaS, AI companies and professional services build distinctive brand identities that are clear, consistent and ready to scale. I work with founders and marketing teams to turn business strategy into a strong visual identity — from positioning and brand direction to identity systems, guidelines and real-world implementation. My work goes beyond creating a logo or individual assets. I build brand systems that give teams a clear foundation for making consistent decisions as the business grows. 🧠 What I can help with • Brand identity systems • Brand strategy, positioning and messaging • Logo design and visual identity development • Rebrands and brand evolution for growing companies • Brand guidelines and scalable design systems • Websites, pitch decks and key marketing assets • Ongoing creative direction and brand support Many collaborations start with a focused project and evolve into longer-term partnerships. I’m equally comfortable helping define a brand from the ground up or stepping into an existing identity that needs more clarity, consistency and structure. I use AI selectively for research, exploration and ideation, while strategy, positioning and identity development remain intentionally directed and crafted by me. 🤝 Why clients work with me • I understand the business before designing • I bring structure to brands that have become fragmented • I connect strategy with visual execution • I build systems that teams can actually use • I think beyond the immediate deliverable 💬 What clients say “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 taking on new projects.
