Adam Salisbury

Systems Integration Expert

Twenty years of experience architecting and developing software solutions, I focus on integrating otherwise disparate systems, from legacy platforms to modern cloud-native solutions. I help organisations connect their systems, migrate their data, and build the APIs that make it all work.

Technologies

C# .NET Web API TypeScript Node.js Rust T-SQL PL/SQL MongoDB Azure Bicep Docker Kubernetes SharePoint Graph API OData GraphQL Power Automate

What I Do

I specialise in making systems work together. Whether you're opening up a legacy application, building an SDK, working with microservices, or merging systems, I design and implement integration solutions that are secure, autonomous, maintainable, and built to last.

Core Services

  • Systems Integration Architecture & Development
  • RESTful API (OpenAPI/Swagger specification)
  • gRPC API (protobuf specification)
  • SDK & Library Development for proprietary APIs
  • Azure Solutions (Functions, Service Bus, API Management)
  • Data Migration & Transformation (Oracle, SQL Server, MongoDB)
  • Microservices Strategy & Implementation
  • Message Queues & Event-Driven Architectures
  • API Health Monitoring & Observability

Integration Challenges I Solve

  • Legacy modernisation: Opening up closed systems through REST APIs or gRPC
  • SDK development: Creating developer-friendly libraries for your proprietary web APIs
  • M&A integration: Merging data sources and systems following acquisitions
  • Microservices: Designing and implementing service-oriented architectures
  • Data migration: Moving and transforming data between platforms
  • System connectivity: Integrating CRM systems, logistics platforms, stock management systems, and SaaS applications

How I Work

Based in the UK, I work with clients worldwide. I engage on both fixed-price projects and day rate arrangements, with typical engagements ranging from one to six months. I work independently or integrate seamlessly with an existing development team, delivering remotely to clients of all sizes, from start-ups to enterprise organisations.

Based in London, I am also able to work on site in the central London area when required.
