What I'm looking for

I am seeking API/integration roles where I can design and implement scalable middleware solutions, lead API-led connectivity efforts, work with CI/CD pipelines, and contribute to secure, high-availability systems.

I am an integration-focused API and Mule ESB developer with 7+ years of experience designing and implementing enterprise integration solutions using MuleSoft, IBM DataPower and related middleware. I have delivered API-led connectivity, RESTful and SOAP services, and complex message flows integrating mainframes, databases and J2EE applications.

My strengths include DataWeave/MEL transformations, CI/CD automation with Jenkins/Maven/Git, and working across CloudHub and on-prem runtimes. I have led design discussions, authored technical documentation (TSD, FRS, NFRS), and supported 24x7 production operations while collaborating with product owners, QA and support teams.

I bring deep hands-on expertise in MQ/FTP/JMS protocols, XML technologies, Java-based web applications, and middleware security (OAuth, SSL, PKI, WS-Security), and I focus on building robust, maintainable integration solutions that meet performance and reliability goals.
