Product Designer · Founder
Turning complexity into clarity.
Hi, I’m Luis. I design web and mobile products for B2B, B2C, and SaaS teams — and I’m currently building at the intersection of product design, AI workflows, and community. I’m a founder of The Hooman Loop and the organizer of Cursor Philly, where I help designers, builders, and operators explore how AI changes the way we create software.
Strategic Design for Digital Products
What I Do
I help product teams bring clarity to complex systems—whether that means improving usability, visualizing data, or scaling design infrastructure. My work spans product strategy, research, interface design, and data storytelling—all rooted in systems thinking and business impact.

User Experience
I design with empathy and clarity—creating seamless, human-centered experiences that make technology feel intuitive, accessible, and genuinely helpful for the people who use it daily.
Interface Design
I build clean, practical interfaces that balance structure, rhythm, and personality— bringing clarity to complex systems and delight to everyday interactions through intentional, beautiful design.
User Research
I uncover user needs through interviews, testing, and journey mapping— translating insights into decisions that reduce risk, improve usability, and ensure products solve the right problems.
Data Visualization
I turn complex data into clear, actionable stories—designing dashboards, visual systems, and reports that reveal patterns, highlight insights, and support faster, more confident decisions.
Meet Luis
I’m Luis Cielak, a Lead Product Designer based in Philadelphia, originally from Mexico City. I help organizations turn complex ideas into clear, intuitive digital experiences—with craft, empathy, and measurable results.
My design journey didn’t start with wireframes. It began with asking better questions: Why is this broken? What’s standing in the user’s way? How do we make this simpler, faster, or more humane?
Over the past decade, I’ve led design across fintech, B2C, B2B SaaS, e-commerce, and data-rich platforms—often working on products where the stakes are high and the systems are complex. Whether I’m building a design system, running discovery workshops, or shaping strategy with stakeholders, I focus on delivering clarity—for users and for the business.
I thrive in ambiguity and love connecting dots across research, interface design, and information architecture. I believe great UX is invisible but undeniable—it builds trust, reduces friction, and scales beautifully.
When I’m not in Figma or interviewing users, you’ll find me brewing kombucha, perfecting a sourdough culture, or teaching design workshops. (And yes, all three involve fermentation, iteration, and a bit of magic.)
Let’s build something insightful, rigorous, and a little unexpected.
