Product discipline
Owning software means handling releases, privacy, compatibility, support, pricing, and iteration—not only proposing ideas. That discipline carries directly into client work.
Every product begins with a narrow problem and a clear user outcome.
Product screens, demos, release status, and documentation make claims inspectable.
Data handling and product limitations are described in plain language.
Users can find current compatibility, help, and product-specific legal information.
Kastovia announces products when there is a usable release, supporting evidence, and a clear support path.
