Hi, I'm JonI build and consult on mobile apps and websites. I have also made a few independently-developed apps like “BOCA” and "Caption This”. I have been building apps in React and React Native since both platforms were first announced. In that time, I have worked as a consultant and full-time employee for many agencies and startups. I have also worked alongside well-known design consultancies and product studios. I am experienced in turning design deliverables into pixel-perfect user interfaces. I can hit the ground running on any project, whether as an individual contributor or technical leader.
