About Me
I’m a full-stack developer and designer with over 8 years of experience building digital products that people love. Based in San Francisco, I specialize in creating clean, performant web applications using modern technologies.
My journey started with a fascination for the intersection of design and technology. Today, I bring that same curiosity to every project, whether it’s crafting pixel-perfect interfaces, architecting scalable backends, or designing intuitive user experiences.
When I’m not coding, you’ll find me contributing to open-source projects, mentoring aspiring developers, or exploring the latest design trends.
