Software platforms
Products built around the people using them. We design interfaces and domain models for tasks such as planning duties, managing reservations and reviewing records.
Pajic Systems
Software, identity
and infrastructure.
We develop software platforms, operational tools and the infrastructure behind them. Our work spans aviation, digital identity, service operations and credential verification.
From the interface
to the infrastructure.
We build the application people use and the systems it depends on: data models, APIs, identity, operational rules and integrations.

APIs and integrations
Connect frontends, services and operational data. Shared contracts keep business rules in one place instead of rebuilding them in every interface.
Identity and trust
Authentication, scoped access and credential evidence. Define who can act, what information a service receives and how a record can be checked.
