Cloud-native microservices.
Kubernetes-orchestrated. Each module is an independently deployable service. No monolith, no in-flight migration risk.
Built for the room with the architecture review. Microservices on Kubernetes, an event spine on Kafka, an API-first surface for every Micro AI, HSM-backed key management, and data residency that defaults to where your regulator wants it. This is the page that closes the CTO’s questions.
The platform is structured as six logical layers. Each layer exposes a versioned API. Data flows up; events flow across. Region pinning lives in the data plane, so the same application code runs in every region with no fork.
Kubernetes-orchestrated. Each module is an independently deployable service. No monolith, no in-flight migration risk.
Apache Kafka event spine. Every change is an event. The platform is replayable from any point in time.
Every module exposes a versioned REST + GraphQL API. SDKs maintained alongside the API surface.
mTLS service-to-service. No implicit network trust. Every call authenticated and authorised.
Data residency is enforced in the data plane. Application code is region-agnostic; data never leaves its jurisdiction.
Active-active multi-region. In-region failover in seconds. Cross-region failover within a minute.
Every load-bearing component is mature, well-supported, and widely understood. This is not the place to chase novelty.

Regional digital identity wallets, region-by-region.
Every Micro AI is reachable via the same API surface. SDKs are first-class — not afterthoughts. Sandbox access is granted with the first demo.
REST · GraphQL · Webhooks · SSE.
REST for transactions. GraphQL for complex queries. Webhooks for event subscriptions. SSE for live streams.
OAuth 2.0 · OIDC · mTLS.
OAuth 2.0 for clients, OpenID Connect for federated identity, mTLS for service-to-service.
iOS · Android · JS · Python · Java.
Five first-class SDKs maintained alongside the API. Generated from the same OpenAPI spec.
Dedicated tenancy — dedicated infrastructure in your chosen region. Available on AWS, Azure, or GCP.
In your data centre — for regulated firms whose supervisor requires it (for example DIFC, ADGM). Scoped per engagement.
We’ll walk your engineering team through every layer of the stack, answer architecture-review questions on the record, and provide a written architecture brief afterwards.
