About

Who is devmobx?

I'm Craig Chick, a fullstack developer with 5+ years building web and mobile products. I specialise in React Native, Next.js, and .NET/C#, but I'm comfortable across the entire stack, from database design to pixel-level UI.

Most recently I spent three years at UpCoop building the UpCohésia banking app, a React Native application serving 50,000+ users, and its internal Angular monitoring dashboard. Before that I built client projects across sectors at TX Studio, introducing monorepos, Firebase, and modern design systems along the way.

I care about code quality, security, and building things that don't fall apart when real people use them. I'm Agile-trained and have worked in structured cross-functional teams as well as solo freelance engagements.
