Summary

With over 7+ years of expertise in the SDLC, I bring hands-on proficiency in MuleSoft ESB and Anypoint Platform, focusing on financial, insurance, and retail domains. Possessing excellent communication and documentation skills, I specialize in Enterprise and Mule ESB 4.x, actively engaged in project integration using MuleSoft and Synatic tools. My contributions have improved system efficiency, enhanced data accuracy through automation, and optimized performance by resolving technical issues. Collaborating seamlessly with cross-functional teams, I excel in designing RAML specifications, building APIs, and managing API life cycles. Additionally, I have strong experience in implementing SOA using XML-based web services, SOAP, and REST, with proficiency in CI/CD processes and various IDEs. My extensive experience covers all SDLC phases in an Agile environment, working with RDBMS like MySQL, SQL Server, ORACLE, and DB2, and familiarity with SAP and Salesforce Integration with Mulesoft.
