Think. Design. Build.
I bring 15+ years of product craft, design leadership, and strong technical skills to every project.
Today, I design and build with AI directly in the codebase, from product thinking to launch, with less handoff.












Juan Estupinan
Product Design Lead
I work across strategy, design, and front-end, helping teams move from idea to product with less friction.
I combine AI agents for speed with a code-to-design loop for craft. That's how I build.

From Design to Codebase
Most designers deliver specs. I use agentic development to design, prototype, and ship directly in the codebase, so the result stays close to what I designed.
Product Design
I design products that balance clarity, usability, and scalability. From interaction patterns to design systems, I create interfaces that are easier to use and faster to build.
AI Product Development
I build with AI in two complementary modes: agentic development for speed, and a code-to-design loop for craft.
User Experience (UX)
I study user behavior to uncover real needs and translate insights into clear, usable experiences. Research and testing keep decisions grounded.
Front-end Development
I ship interfaces, not just specs. I move from design intent to working front-end in React/Next.js and Webflow, which speeds up iteration and improves build quality.

How I Help Teams Ship Better Products
Senior Product Partner
You get a senior partner with 15+ years of experience building digital products: someone who clarifies direction fast, aligns stakeholders, and contributes from day one.
From Design to Codebase
Most designers stop at the handoff. I design and build directly in React/Next.js and Webflow, which means fewer mismatches, faster cycles, and interfaces that stay true to the design intent.
Building with AI, for real
Product development has changed. I combine AI agents for speed with a code-to-design loop for craft. This is not theory. It's how I build products today.
Leading with Clarity
As Head of Mobile at Condé Nast, I led cross-functional teams of 10+ designers and engineers. That experience shaped how I lead: aligning stakeholders, setting direction, and improving design quality through clear decisions and feedback.
