About
Hi! I'm Mario Callejas. I'm a fullstack developer, ready to take my skills and create the next big thing with you. I can build anything I put my mind to and tackle any part of the stack. But more than anything, I have a soft spot for making easy-to-use, functional products that people use and enjoy. I'm interested in tackling problems that really challenge me and put my skills to the test.
I was born in Venezuela, raised in the United States, and now living in Norway. My experience varies from working at Fortune 500 companies to Silicon Valley based startups.
Have a cool project to work on? Let's meet!
