API Systems & Integration Services

REST and gRPC service layers that connect the systems you already run.

Service overview

Integration work fails on the edges: retries, idempotency, partial failure and versioning. We design the contract first, publish it, and build services that behave predictably when a counterpart does not.

What the engagement includes

  • REST and gRPC service design with published contracts
  • OpenAPI specifications and generated client stubs
  • Message queues and event-driven integration patterns
  • ERP, CRM, payment and logistics connectors
  • Idempotency, retry and backoff strategies designed in, not retrofitted

What you receive

  • Versioned API contract and reference documentation
  • Integration services with contract tests
  • Operational runbook for each connected system
