Accessibility audits
I test your website or app for real accessibility: not just whether it meets the rules, but whether it's truly usable for everyone - including people with a disability.
Websites and apps people can actually use.
I'm Sebastian. Through Hello Pixel, my freelance studio, I help companies and organisations build and improve websites and apps that stay accessible, fast and easy to maintain.
What I do
Component quality
I assess design systems, patterns and documentation with maintainability, accessibility and user experience in mind - so they're built to last, easy to adopt, and work for everyone.
Frontend architecture
I help teams build cleaner, more resilient CSS and JavaScript foundations.
Performance review
I find out what's slow and why, and give you concrete ways to fix it.
Code implementation
Hands-on work: building or refining interfaces and components.
Workshops
I run hands-on workshops on accessibility, CSS and sustainable web practices - focused enough to stay sharp, practical enough to use straight away.
How I work
I prefer plain language, honest conversations about scope, and work the next developer can pick up without a treasure map. Accessibility isn't an extra for me. It's part of building a good website or app.
