Build Azure applications and integration services using C# and .NET, with services such as Azure Functions, App Service, and API Management to connect Dynamics 365 with the wider platform.

Develop and consume REST APIs, Dataverse Web API and OData endpoints, and GraphQL APIs. Define clear contracts, validation, versioning, and error handling with the teams that own connected systems.

Own quality and operability through automated unit, integration and API contract tests, code reviews, monitoring and troubleshooting: document technical decisions and support releases and production incidents.

Work closely with business and engineering colleagues to clarify requirements, agree acceptance criteria and deliver usable solutions in small increments.

Experience with Apache Kafka and event-driven integration, including producers and consumers, consumer groups, delivery semantics and idempotent processing.

Hands-on experience with Git, automated testing, and CI/CD, particularly application lifecycle management for Dynamics 365 and Power Platform, and deploying Azure applications.
