  • Accessibility: Strong understanding of and experience with accessibility standards (WCAG).
  • Cloud & DevOps: Experience deploying and maintaining applications on cloud platforms (Azure or GCP) using Git and CI/CD pipelines.

Preferred Qualifications

· Experience with containerization (Docker, Kubernetes) and microservice orchestration.

· Experience with event-driven architecture and messaging systems (e.g., Kafka, RabbitMQ).

· Familiarity with Agile/Scrum methodologies in a large-scale enterprise environment.
