I build the content infrastructure technical products publish on.

Schemas, content models and the CMS setup under your website, including the pages AI generates. Marketing publishes without waiting on engineering.

If the CMS is slowing your team down, write to me.

Definition

noun

Content infrastructure

Content infrastructure is the schemas, content models, and CMS architecture a technical product publishes on — the layer beneath the content. When it’s built well, every page type is made of the same parts: typed fields, validation rules, references between documents, and the editing screens set up around them.

Where I help

Only content infrastructure.

Schema and content-model design for technical product companies, from scratch or restructured in place.

CTO
Pages AI generates are validated against the schema every other page uses, so there’s no one-off code to maintain. A CMS migration runs while the site stays live and editors keep publishing.
Head of Marketing
Your team builds pages from ready-made sections. For ABM, AI drafts a page for each target account from those sections and leaves each one unpublished in the CMS.

Mentoring

The craft, passed on.

Since 2024 I’ve mentored at hackathons around Europe, including HackNation PL, and co-organised Hackathon for Builders and ADPList meetups in Poland. I help teams cut scope to something that still works after the event.
