Who we are02 / 06

The vendor I'd want to hire.

Nate spent years on the buyer's side as a software engineer and project manager, doing the testing vendors skipped and writing the documents they didn't. Keel North is built on what made projects work.

  1. Work arrived untested, and users found the bugs.You review the work. You don't test it.
  2. The team wrote the vendor's documents.We write the requirements, design and handover documents.
  3. A stalled project went to a new vendor who wanted to start again.Code and accounts are in your name from day one, with a handover pack anyone can pick up.
  4. The senior at the pitch was not the person who built it.The engineer you meet is the engineer who builds it.

Security and terms06 / 06

Security practice

  • Reviewed at the startA security and PDPA review is part of every Blueprint, before the build, not at the end.
  • Least accessWe work through named accounts with only the access the work needs, and remove them at handover.
  • No secrets in chatPasswords and keys live in a password manager or secrets store, never in chat, email or the code.
  • Audit logsStaff and admin actions are logged, so you can always answer who changed what.
  • TestedAutomated tests run on every change before it reaches you.
  • Personal dataCollected only where the system needs it, with access by role and a signed data processing agreement.
