About this gig

I am a MuleSoft integration specialist, based in Europe, with hands-on experience designing, developing, testing, and troubleshooting enterprise Mule 4 applications.


I can help you with:

  • Mule 4 application development and support
  • REST and SOAP API integrations
  • Salesforce and other system integrations
  • DataWeave transformations
  • Anypoint Studio and Runtime Manager
  • MUnit tests, mocking, and coverage
  • Production error investigation and bug fixing
  • Logging, correlation IDs, and performance analysis
  • Maven build and deployment issues
  • Code reviews and integration improvements


I have practical experience supporting complex production integrations, analyzing logs, identifying root causes, and implementing reliable fixes without disrupting existing business processes.


Before placing an order, please send me a short description of your requirement, relevant error messages, and the expected outcome. I will review the scope and recommend the appropriate package.


My minimum engagement is one hour at $60. Larger or more complex work can be arranged through a custom offer.
