Principal Software Engineer Carvana

With a background in design and a passion for technology, front-end engineering became the perfect intersection of creativity and problem-solving for me. I love crafting intuitive user experiences and finding elegant solutions to complex, user-facing challenges.

Since starting my journey in 2005, Ive grown through hands-on experience, working on widely used digital products and contributing as a collaborative, resourceful team member. Now based in Austin after many years in San Francisco, I bring a thoughtful, user-centered approach to every project I take on.

Experience & Skills

I've contributed to teams across the U.S. and Europe—partnering with startups and established organizations like Anki, World Market, UC Boulder, and more. Each project brought its own challenges, and I take pride in crafting thoughtful, effective solutions that align with both user and business needs.

I specialize in building, testing, and shipping modern front-end experiences using tools like JavaScript, TypeScript, React, GraphQL, Node.js, and more. I'm passionate about clean code, design quality, and collaborating with others to turn ideas into scalable, user-focused products.

What Drives Me

Whether in code or life, I'm motivated by growth. My background in competitive sports taught me to push limits, stay curious, and keep improving — lessons I carry into my work every day. I'm constantly exploring new technologies, refining my skills, and challenging myself to solve problems in more thoughtful and effective ways.

Beyond the technical side, I care deeply about collaboration, mentorship, and creating environments where people can thrive. I believe the best work happens when curiosity meets discipline — and when people bring their whole selves to the table.
