Workspace setup with design tools and dual monitors

I'm a multidisciplinary designer and developer with a passion for crafting digital experiences that are both beautiful and functional. Based in San Francisco, I work with startups and established brands to bring product visions to life.

My approach blends creative intuition with technical rigor — I believe the best products emerge when design and engineering work in harmony, not in silos. Every project starts with understanding the people who will use it.

Over the past 5+ years, I've delivered 50+ projects across product design, web development, brand identity, and mobile experiences — serving clients in 12 countries across fintech, health, e-commerce, and creative industries.

When I'm not designing or coding, you'll find me exploring photography, experimenting with generative art, or hiking the trails around the Bay Area.

Let's work
together

Have a project in mind, a question about my work, or just want to connect? I'm always open to conversations about design, technology, and building great products.

Every project begins with discovery — understanding your goals, users, and constraints. I then move through research, ideation, prototyping, testing, and development. I believe in iterative collaboration with regular check-ins to keep everything aligned.

It depends on scope and complexity. A simple brand identity or landing page might take 2-4 weeks. A full product design with development typically runs 8-16 weeks. I'll give you a clear timeline after our initial conversation.

Both! I love working with early-stage startups to help shape their product vision, and I equally enjoy partnering with established teams to refine and elevate their existing products. Every project gets the same level of care and attention.

For design, I primarily use Figma, with occasional work in Illustrator and After Effects for brand and motion. For development, I work across React, Next.js, Vue, Node.js, and React Native. But tools change — the principles of good design stay the same.
