FAQ

Reasonable questions.

If something isn't here, write us. We reply directly.

01

How do you handle security and sensitive data?

Security is part of the design, not an add-on: access control, encryption, auditing and practices built for regulated environments like banking, healthcare and insurance.

02

Do you work with clients abroad?

Yes. We're incorporated abroad and most of our clients are international. International contracts and invoicing with no friction.

03

Do you integrate with in-house teams?

Yes. We plug into your team, your tools and your repo. Our PRs get the same review as your internal ones.

04

Who owns the code?

You do. From commit one, in your repo, under your license. We never reuse one client's code on another project.

05

Do you offer post-delivery support and maintenance?

Yes. We leave documentation and runbooks, and include post-delivery support so your team can operate the system with confidence.
