What I'm looking for

I want to lead MuleSoft/API-led integration architecture and governance, stay hands-on with production-grade deployments and monitoring, and mentor teams to deliver secure, high-performance APIs with smooth release processes and strong day-2 support.

I’m a MuleSoft Architect with 8 years of experience in MuleSoft integrations and 7 years in Java microservices, focused on building scalable, secure, and production-ready solutions. I work across the full lifecycle—API design, architecture, implementation, testing, deployment, and day-2 operational support—while keeping integration quality and non-functional requirements front and center.

I’m hands-on with Anypoint Studio and Mule ESB, building RAML/Swagger-based APIs and managing API catalogs, accelerators, health checks, and production deployment checklists. I’ve led team execution and delivery end-to-end, including sprint planning, daily stand-ups, reviews, retrospectives, Jira/Azure Boards workflows, and strong release/deployment management across environments.

From real-time streaming and synchronous/asynchronous patterns to messaging, bulk, and batch processing, I design integration mechanisms that fit business needs. I drive API governance and security (OAuth/JWT/OKTA and enterprise policies), perform production log analysis using Splunk/ELK/Azure Logs for hotfixes, and support monitoring, incident management, and problem management—so teams can ship confidently and operate reliably.
