API Design & Development
REST, GraphQL and gRPC APIs with clear contracts, versioning and documentation.
01 / Approach
Systems that talk to each other.
Most organizations run dozens of applications that were never designed to work together. Data is copied by hand, exported to spreadsheets or synchronized by fragile scripts. We design integration as architecture: clear APIs, reliable messaging and monitored data flows, so systems stay connected as they change.
02 / What we build
Six capabilities, one architecture.
API Management
Gateways that handle security, rate limiting, monitoring and developer access for internal and partner APIs.
Event-Driven Integration
Message queues and event buses that connect systems without tight coupling, and keep working when one of them is down.
Enterprise & SaaS Integration
Connections between ERP, CRM, payment, identity and other third-party platforms.
Legacy System Integration
Modern interfaces around older systems, so they can take part in new workflows without being replaced first.
Identity & Secure Access
Single sign-on for users and secure authentication between services across connected systems.
03 / Capability matrix
The technical detail.
| Capability | Typical question | Core techniques | Tooling | Deliverable |
|---|---|---|---|---|
| API Design | How should other systems talk to ours? | Contract-first design, versioning, documentation | OpenAPI, ASP.NET Core, GraphQL | Documented, versioned APIs |
| API Management | Who is calling our APIs, and how often? | Gateway policies, throttling, analytics, developer onboarding | Azure API Management | Managed API gateway and portal |
| Event-Driven Integration | How do we keep systems in sync without tight coupling? | Queues, publish/subscribe, event schemas, retries | Azure Service Bus, Event Grid, Kafka | Reliable messaging backbone |
| Enterprise & SaaS | Can our ERP and CRM share data automatically? | Connectors, data mapping, synchronization workflows | Logic Apps, custom connectors | Automated system-to-system flows |
| Legacy Integration | How do we use this old system in new workflows? | Adapters, API wrappers, file and database integration | .NET, custom adapters | Modern interface to legacy systems |
| Identity & Access | Can users sign in once across all our systems? | Single sign-on, token-based auth, service identities | Entra ID, OAuth 2.0, OpenID Connect | Unified authentication |
04 / Method
From a map of systems to monitored flows.
-
01
Map
Inventory systems, data flows and owners, and identify where integration breaks today.
-
02
Design
Define contracts, message formats and error handling before writing code.
-
03
Build
Implement integrations in small, independently deployable pieces.
-
04
Test
Verify each integration end to end, including failure and retry scenarios.
-
05
Monitor
Track every flow in production, with alerts when messages fail or slow down.
05 / Principles
How we build integrations.
Integrations fail in predictable ways. These principles are how we design for that.
-
Contracts first
Interfaces are agreed and documented before implementation starts.
-
Loose coupling
Systems can change or go offline without breaking everything connected to them.
-
Safe to retry
Messages can be retried without creating duplicates or inconsistent data.
-
Observable flows
Every message can be traced from source to destination.
-
Secure by default
Every connection is authenticated, encrypted and limited to what it needs.
-
Documented for your team
Integration maps and API documentation stay current with the code.
