Hello! I am an experienced web developer and entrepreneur. My passion and strength lies in rapidly prototyping and validating new ideas through code. I also have experience managing multiple software teams and scaling businesses to millions of dollars. My family and I live in San Jose. I'm always interested in meeting smart people and learning about new opportunities. Please reach out through Email or LinkedIn.

My work history includes:

• Instrumentl: Grant software for non profits.
• ToolWall The first digital organizer for your physical tools.

These days I write Ruby and Javascript professionally and Go for fun. My current/past interests include AI, photography, woodworking, CNCs to name a few.
