• Expert knowledge of XML, XSD, XSLT 2.0/3.0, JSON, and related transformation libraries.
• Solid understanding of canonical data models, schema design, and common B2B integration protocols (REST, SOAP, GraphQL, FTP/SFTP, EDI).
• Hands‑on experience with message queuing or event streaming technologies (e.g., RabbitMQ, Azure Service Bus).
• Proficiency with GIT, CI/CD pipelines, and automated testing frameworks.
• Strong analytical and problem‑solving skills with a passion for clean, maintainable code.

Desirable
