What I'm looking for

I seek an integration-focused role where I can design and lead API programs, work with cloud platforms and secure integrations, collaborate cross-functionally, and continue advancing technical and leadership skills.

I am an integration engineer with three years of hands-on experience designing and delivering robust API and integration solutions across enterprise systems such as SAP S/4HANA, Elastic, PowerBI and Microsoft Business Central. I build REST and SOAP APIs from architecture and data modeling through implementation, testing and Cloudhub 2.0 production deployment, and I have driven end-to-end API programs connecting 20+ downstream systems.

I bring strong Mulesoft expertise (Connectors, DataWeave 2.0, Cloudhub, Runtime Fabric), practical DevOps experience with Git, Jenkins, Bitbucket and Azure DevOps, and a security-first approach including Azure Key Vault and IAM. I am collaborative, leadership-oriented, Mulesoft-certified (Level 1 & 2), and committed to continuous learning and delivering high-quality integration outcomes.
