Lubos Kmetko

I’m part of xfive’s marketing team, currently focused on developing and maintaining our company Webflow websites. With 19 years at xfive, I started as a senior front-end and WordPress developer before moving into leadership roles in development standards and quality assurance.

Though I don’t work directly with partners, I use my analytical skills to improve web development processes and contribute content to our blog — where some posts have reached hundreds of thousands of views. I hold HubSpot Digital Marketing and Salesforce certifications.

I enjoy the collaborative and pragmatic approach at xfive, where compromises lead to shared success. Outside work, I’m passionate about rock climbing, snowboarding, and reading. After a decade away, I recently returned to developing websites — this time in Webflow — and it’s been fun.
