Senior🎓
Top SchoolJohn Van Der Loo is a Senior Frontend Developer with over a decade of professional experience and more than 20 years working in web development, specialising in JavaScript/TypeScript, React and Vue.js to build accessible, user-focused interfaces. He has led frontend efforts at companies ranging from Atlassian to privacy-focused Whispli and climate startup Pathzero, where he built and matured design systems like "Terra" and drove migrations of large legacy codebases.

He brings strong testing discipline, CSS preprocessor expertise and practical UX tooling skills (Figma, Photoshop, Atlassian suite), and prefers projects that have measurable social impact. Based in Gosford, Australia, John combines veteran front-end craftsmanship with a knack for modernising older systems while keeping them stable in production.
