Our team
Karlijn Löwik
CEO
I'm on a mission to make web performance a business priority for eCommerce companies. As CEO with extensive IT experience, you might see me with onboarding, finances and legal matters. I speak internationally on web performance, advocate for RUM, and champion women in tech.
I also serve as Co-chair for the RUM W3C Group and boardmember of Mage-OS NL. And yes, I coined "Sitespeed User Experience (SUX)" – because good SUX sells! 😉
Roderik Derksen
Commercial director
As the commercial director, you will frequently hear from me during the onboarding process. I have over 15 years of experience as an independent marketer with SEO, SEA, and marketing strategies. My background is in business development.
I'm also in charge of RUMvision partnerships. Please contact me if you are a development agency, marketing agency or a site speed consultant.
Erwin Hofman
CTO & Pagespeed expert, GDE
As CTO, I help solve technical problems. If you're having trouble with site speed, this can be in a consulting role. I am also in charge of fixing bugs and coming up with new features.
For the past 18 years I've been a full-stack developer. The last 5 years I've also been a page speed consultant for e-commerce. Insights gathered in both roles have resulted in RUMvision.
Jordy Scholing
Customer success & Google Developer Expert
When you first start using RUMvision, I am usually your first point of contact. I assist you with onboarding and questions. I'm also very active with writing blogs, marketing and sharing knowledge about page speed and consultancy.
I enjoy engaging with people who are just starting out in performance, so feel free to reach out!
Johan Jorritsma
Developer
As a front-end developer, I like making websites that load quickly, are easy to use, and don't have to compromise on design. I code in CSS, HTML, and JS, and I make the templates RUMvision needs to tell you our story.
I mostly work as a front-end developer for Blue 2 Blond ( Erwin and Karlijns webagency).
Robert Silos
Developer
I'm a full-stack developer, and help with API connections, integrations, coding and front-end challenges that also require some backend knowledge.
