I made a CV-to-portfolio site builder. Questions about the parts that were hard

I built Cveelo, a tool that takes a CV and turns it into a published portfolio site. Some parts that were harder than I expected:

– Getting an LLM to extract a CV without inventing anything. I use structured outputs bound to a schema with every optional field nullable, and retry once on a validation failure.

– Counting visits with no cookies and no script on the page. The request layer hands the visit to a signed internal route, and the visitor hash is deleted after two days.

– Wildcard subdomains plus custom domains, and keeping reserved names like www and api from being taken as slugs.

Stack: Next.js, Postgres on Neon, Deno. Happy to go into any of it. https://www.cveelo.com/
