I'm a Los Angeles-based full-stack developer with over 11 years' professional experience. As an incredibly fast learner, I have the ability to pick up new languages and frameworks in a short amount of time. I've worked on large-scale projects from start to finish, as well as jumped in at the last minute to help finish products before launch. In my free time, I also code personal projects and participate in mentoring programs for people interested in learning to code.
