Digital / Services

Hi 👋

I'm an Amsterdam-based full-stack / front-end developer called Koen Schaft. Since the late 90s I've been building websites, primarily focussed on you — the user.

My drive is building digital products that simply work, I personally believe in, and resonate with the target audience. I strive to write “easy to reason about”-code, which is maintainable and scales well. I'm pragmatic, but don't like to compromise on quality. I like to challenge the status quo, but favour proven technology above jumping every shiny new bandwagon.

I've worked at PwC’s Experience Center, GRRR, and Superhero Cheesecake. For a short resume, view my LinkedIn profile.

Services

Due to my tendency to want to be able to “do it all”, I'm quite proficient in creating digital products in many facets of the stack. My core focus is front-end, usually combined with some back-end coding, devops and occasional digital interface design.

Things I can help you with:

Building scalable web applications Think data-driven interactive dashboards, headless CMSs, with things like: React/Vue, Next/Nuxt, TypeScript, GraphQL, Laravel/PHP, Python, ...
Building ‘simple’ websites Think static campaign websites, prototypes, proof of concepts. E.g. templating, styling, vanilla/micro JavaScript, static site generators, ...
Testing (unit, integration, E2E) Shipping too many bugs? I'll help set up testing infra with tools like Jest + Testing Library, Playwright, ...
Devops / tooling Proficient in working with or partially setting up CI/CD, pipelines, deployments, CLI tools, Git workflows (branches, rebasing), Docker, VMs, Kubernetes, ...
Performance optimization / caching Lots of experience optimizing front-end assets, static backend caching, CDN distribution and invalidation, ...
Accessibility / usability WCAG 2.2 compliance, audits with designers, ...

Just reach out, and I'll let you know if I'm the right person for the job.

Awards
