Front-end Developer, Castricum, Netherlands
Hello, I'm Sander
A 30-year-old front-end developer from Castricum, living there with my wife. I build interfaces that are fast, accessible, and actually pleasant to use.
San Gimignano, Italy, 2022
How I got here
It started at 15, too many games, too many questions about how they worked. At 16 I enrolled in Software Engineering at MBO Niveau 4, learned C#, HTML, CSS, PHP and SQL. Still not satisfied, I moved on to Communication & Multimedia Design at the HvA, where my front-end skills and UX thinking really clicked. I landed my first developer job at QStylez while still studying.
From there: 24i (streaming tech, innovation team, led a LightningJS POC with a 16% speed improvement, built a full-stack CRM in Vue + PHP), then Beeldr (clients ranging from Microsoft and Vattenfall to small local businesses). Most recently via Capgemini, on the two biggest projects of my career so far.
What I work with
Vue / Nuxt and React / Next.js are my main stack, backed by TypeScript and SCSS. I've worked with component architecture and design systems, and used Redux, Atomic Design, Bootstrap and styled-components. I've done AngularJS, PHP and MVC patterns too. Certified in Angular and Web Accessibility (WAIO.1x). Jira and Confluence are basically muscle memory.
What I've been building
Used by millions of Dutch citizens weekly. Rebuilding it from scratch with a headless React / Next.js architecture, while maintaining the existing Vue 2 / PHP / Twig stack still in production.
Modernising the documentation system for parliamentary motions and papers. React / Next.js, Redux, custom CSS, extending features, writing tests and supporting teammates on complex problems.
Life outside the screen
Smart home builds, a recipe swiper from my Notion database, AI tinkering. Socially: a friend group of eleven, my wife, good films and RPGs. Physically: padel, tennis, running, and since 2022, hiking. Eight days through Norway was enough to get me hooked.
