How I handle your systems and data

Reviews and builds need access to real systems. This is how that access, and the data behind it, is handled.

Last updated November 6, 2026

Access

I work with the least access the job needs: read-only for reviews, scoped credentials for builds. Access is removed when the engagement ends.

Your data

Client data stays in your accounts and systems wherever possible. I don’t copy production data to personal devices, and I don’t use your data to train models.

Confidentiality

I sign NDAs on request, and I don’t name clients or show their work without written permission. Employer work on this site is described without internal names or screenshots.

Model providers

When a system calls a hosted model, we choose the provider and its data-retention settings together and write them down.

How the systems are built

The systems I ship use the same safeguards described in the case studies: verified webhooks, idempotent writes, per-tenant isolation, role-based access and audit logs.
