Build and consume RESTful APIs and event-driven services, applying clean architecture and domain-driven design where appropriate.
Implement integrations with downstream systems and external partners using REST, messaging (Azure Service Bus, Kafka, or Pub/Sub), and batch interfaces.
Work with relational and non-relational data stores, writing efficient queries and persistence code with JPA/Hibernate.
Containerise services using Docker and deploy to Azure Kubernetes Service (AKS).
Contribute to CI/CD pipelines (Azure DevOps and/or GitHub Actions), with automated build, test, and deployment steps.

Participate in code reviews, design discussions, and architecture sessions; advocate for clean code, performance, and security best practices.
Support production services on a shared rotation, contributing to monitoring, alerting, and incident response.
