Do you sign NDAs?

Yes — standard practice. I sign your NDA template before any commercial discussion or repo access. I also have a short mutual NDA template (PandaDoc, takes ~2 minutes to sign) if you don’t have one drafted.

For larger engagements ($25k+) I’ll also sign a separate data processing addendum if your store handles PCI / GDPR / HIPAA-adjacent data — happy to use yours or supply mine.
