Solution

Enterprise Integration.

APIs, iPaaS gateways, and event-driven middleware that hold up under load. Documented contracts, schema evolution discipline, and the operating cadence integrations actually require, not a Postman collection and a hope.

The condition

Most enterprise integration work is a brittle pile of point-to-point connections nobody documented.

The pattern across enterprise integrations: an API gateway someone stood up in 2019; iPaaS subscriptions that grew faster than the integrations on them; event-driven architecture that's a Kafka cluster nobody owns; partner integrations that broke last quarter and are still broken; and a backlog of new integrations that's been sized at 18 months for the past three years. Integration succeeds when contracts, schema discipline, and operating cadence are all engineered, not assumed.

Prosigns ships integration as a first-class engineering discipline. Documented data contracts at every boundary, schema evolution managed through CI gates rather than post-deploy panic, partner onboarding that scales without re-engineering the gateway, and the observability and SLO discipline production integrations require. FORGE handles the integrations; NEXUS handles the platform; CORTEX layers AI components when relevant.

What success looks like

Outcomes you can track monthly.

Every enterprise integration engagement publishes a metrics dashboard at kickoff and updates it monthly. No vanity metrics, no mystery ROI.

Practice mix

4 practices, orchestrated against one outcome.

Solutions are not single-practice engagements. The roles below show how each practice contributes, the same way a delivery plan names owners and acceptance criteria.

    Platform & Cloud

    Cloud architecture, DevOps, SRE, migrations, data engineering.

    Role here

How we engage

4 phases, orchestrated across practices.

Each phase has named owners across the practices listed above, a shared deliverable, and an acceptance criterion at the program (not the squad) level.

  1. 01

    Integration topology assessment

    Inventory current integrations, classify by criticality and volume, surface schema drift, and design the to-be topology. Output is the rationalized integration map with explicit data contracts and ownership.

  2. 02

    Contracts and schema discipline

    OpenAPI / AsyncAPI contracts for every integration, schema evolution managed through CI gates with consumer-driven contract testing (Pact), and the deprecation discipline that lets schemas evolve without breaking consumers.

  3. 03

    Platform standardization

    API gateway, iPaaS, or custom middleware picked by fit. Event-driven architecture where the workload genuinely benefits; request / response where it doesn't. Observability (OpenTelemetry) integrated end-to-end.

  4. 04

    Operating cadence

    SLOs per integration, contract drift monitored continuously, partner onboarding runbook tested under load, and the operational tooling integration ops actually use. Many engagements continue under Managed Services.

Capabilities

What’s in scope.

Capabilities span all the practices contributing to this solution. Out-of-scope items are named in the SOW too.

  • API design: REST, GraphQL, gRPC, with documented contracts
  • iPaaS: MuleSoft, Workato, Boomi, Azure Logic Apps, picked by fit
  • Event-driven: Apache Kafka, AWS Kinesis, Azure Event Grid, RabbitMQ
  • API gateway: Kong, Apigee, AWS API Gateway, Azure APIM
  • Schema evolution: contract testing (Pact), versioning, deprecation discipline
  • Partner onboarding flows: self-service or assisted, with SLO targets
  • Observability: OpenTelemetry instrumentation across the integration spine
  • API security: OWASP API Top 10, rate limiting, threat modeling, audit logs

Common questions

Asked before the first call.

  1. 01

    iPaaS or custom middleware?

    Workload dependent. iPaaS (MuleSoft, Workato, Boomi, Azure Logic Apps) wins for integration-heavy organizations with diverse partner connectivity needs and operational ownership outside engineering. Custom middleware wins when integration volume justifies the engineering investment, when latency or throughput exceeds iPaaS economics, or when the integration logic has product-level complexity. We tell you which fits, in writing.

  2. 02

    Event-driven or request / response?

    Per integration. Event-driven wins for high-volume, asynchronous workflows where producer and consumer pace independently. Request / response wins for low-volume synchronous reads, well-defined RPC patterns, and cases where the asynchrony genuinely complicates the workload. We design the boundary explicitly. Most production architectures use both at different layers.

  3. 03

    How do you handle schema evolution?

    Contract testing with Pact in CI, explicit versioning policy per integration, and deprecation discipline (sunset dates, consumer notification, automated migration support). Producer changes that break consumer contracts are surfaced in CI before deployment, not after.

  4. 04

    Can you migrate off our existing API gateway?

    Yes: Kong → Apigee, MuleSoft → Workato, custom → managed gateways are all in our active migration portfolio. We design migrations as phased cutovers with documented rollback per integration. Most multi-gateway migrations land in 6–12 months.

  5. 05

    Do you handle partner onboarding?

    Yes: partner onboarding flows, SLO discipline, monitoring per partner, and the operational tooling integration ops actually use. We design onboarding to scale without re-engineering the platform every time a new partner connects.

  6. 06

    What does an enterprise integration engagement cost?

    Topology assessment: 3–5 weeks, $40K–$120K. Integration platform build: 5–9 months, $400K–$1.5M. Multi-platform migration program: 9–14 months, $1M–$3M. Managed Services: $30K–$150K monthly retainer.
