FinTech projects regularly touch multiple systems: core applications, reporting, external APIs, compliance tools. Without a clear picture of data flows and interfaces, dependencies emerge that become expensive later. Technical clarity means: documented data models, explicit interface contracts, defined responsibilities and a traceable architecture view. In this post we show how we create such clarity in practice – pragmatically, without architecture overkill.
This article gives an overview from practice. For an in-depth discussion of your concrete initiative, please get in touch.
