Architecture

Patterns grounded in delivery and operations.

Recurring architecture themes presented without exposing client-sensitive implementation details.

System pattern

Event-driven workflow

API→Domain service→Database→Kafka→Consumer→External system

Explicit state transitions, durable business outcomes, manual acknowledgement where needed, retry classification, idempotency and end-to-end traceability.

System pattern

Cloud-native microservices

Gateway→OAuth2→Spring services→Oracle/PostgreSQL→Redis→Kubernetes

Independently deployable services with standardized security, observability, configuration and CI/CD practices.

System pattern

Data ingestion platform

Sources→Airflow/ADF→Validation→Transform→Snowflake→Analytics

Orchestrated batch ingestion with API integration, data-quality checks, restartability and operational monitoring.

System pattern

Modular enterprise platform

API→Application modules→Domain events→Shared platform→Persistence

Clear module boundaries with reusable cross-cutting components for auditing, security, logging and integrations.
