Jacob Parker

Senior frontend and mobile with over 9 years React and 8 years React Native experience. Skilled in everything relating to JavaScript, CSS, and iOS development.

I’ve my career focused JavaScript projects using React, React Native, and anything related. I’ve got over 7 years’ experience with all the tools you’d expect: TypeScript, Jest, NodeJS, ExpressJS, Webpack, Babel, ESLint, Yarn, ES6; and 3 years’ Apollo and GraphQL. I specialise in building application architectures that scale to support every requirement from product and design: I see my job as making things happen, and seldom say something cannot be done.

React & Web

For React, I’ve used just about everything — Redux, React Router, MobX, React Intl, and many more. I have an incredibly strong understanding of everything CSS, have used just about every tool there is, and even written my own. Whether you’re using Styled Components, SASS, postCSS, CSS Modules, or vanilla CSS — or if you don’t have an architecture for your CSS — I can help.

React Native

If you’re using React Native, you’re probably using some of my code! I maintain the safe-area-context package (used by react-navigation), developed the CSS engine for Styled Components, helped implement the gap and transform-origin properties, and added a bunch of fixes to modals. I’ve worked on a tonne of apps, and never accept React Native cannot do something — I’ll make it!

Polyglot

I have experience in a lot more than I can fit on my CV, including backend experience, functional programming, and if there’s something new, I’ll learn it!

Experience

Tesco

Worked with a team to build a micro-frontend system, delivering business-critical features not available with other solutions, including a module system ensuring consistent dependencies between the server and client, which us to server render pages and achieve better performance and SEO than the legacy site. Overhauled the translation system to ensure translations cannot be missed, which was a common occurrence for the legacy site.
