Deep experience integrating a mix of protocols and end systems, including FTP/SFTP, Queues/Topics, and Databases.
MuleSoft Certified Developer 1 and 2.
Proven ability to clarify success metrics, tie efforts toward delivering business value, and confidently articulate MuleSoft features to business users.

Preferred Qualifications:

MuleSoft Integration Associate or MuleSoft Certified Hyperautomation Specialist certifications.
