I recently finished the Fab Academy in Amsterdam, and now I'm looking for a new opportunity.
I've been working for several years as a web developer at a few different companies. I've gotten the chance to work on some interesting projects, including a Japanese B2B social media app, Western Australian online store and a Korean and Japanese business analytics tool. I'm good with Ruby on Rails and Vue.js, including both frontend and backend work -- Ruby, HTML/CSS, JavaScript, SQL, background jobs and third-party APIs.
