What I'm looking for

I seek senior integration or API roles where I can lead technical delivery, build scalable APIs, work with cloud-native tooling, and mentor teams while advancing automation and CI/CD practices.

I am a Senior MuleSoft Developer and Integration Specialist with nine years of experience designing and building multi-tiered applications using Java, J2EE and MuleSoft. I have over six years of hands-on implementation with Mule ESB 3.x and 4.x across Anypoint Studio, CloudHub, API Gateway and MMC, and I hold MuleSoft Developer certifications (3.9 & 4.1).

I have designed and developed scalable, secure APIs using RAML and DataWeave, integrated enterprise systems such as SAP ECC, Salesforce and PeopleSoft, and implemented CI/CD pipelines with Jenkins and Maven. I’ve worked with cloud platforms and tooling including AWS (EC2, S3, RDS, IAM, CloudWatch), Docker and Terraform, and applied Databricks and Apache Spark for data engineering workflows.

I lead and mentor small teams, coordinate releases with QA and DevOps, and emphasize reusable design patterns, automated testing (MUnit) and performance monitoring to deliver robust integration solutions.
