Our API & Microservices Process

Domain Discovery & Service Boundaries

We map business domains, define bounded contexts, and design clear service ownership to avoid tight coupling.

API Design & Contract-First Development

We design REST/GraphQL/gRPC APIs with OpenAPI specs, consistent responses, versioning, and backward compatibility.

Scalability, Reliability & Observability

We implement caching, queues, retries, idempotency, circuit breakers, tracing, and SLO-based monitoring.

Secure Deployment & CI/CD

We containerize services, set up CI/CD, gateways, secret management, and deploy on Kubernetes or cloud-native stacks.
