Software Engineer - Integration (MuleSoft & TIBCO) at Aptonet Inc. (Contractor for Norfolk Southern) (2018-11 – 2026-01)
- Designed and built SOAP (WSDL) and REST APIs using RAML and OpenAPI, deployed them through MuleSoft API Manager (or Layer 7 API Gateway for TIBCO applications), and secured them with OAuth 2.0.
- Built MUnit test suites to test APIs and flows, keeping code coverage high and catching bugs before deployment.
- Handled data mapping for large integrations using SOAP, REST, JMS (TIBCO EMS, IBM MQ), and FTP/SFTP, working with vendors including Salesforce, iCertis, Railinc, and AAR.
- Connected MuleSoft and TIBCO to Oracle, SQL Server, and Cassandra, ensuring safe queries and handling data in bulk for better speed.
- Transformed data between source and target schemas using XSLT and XPath. Developed Java components to support process flows and called them through DataWeave in MuleSoft or as Java custom functions in TIBCO.
- Deployed MuleSoft and TIBCO applications using Jenkins CI/CD pipelines that pulled code from GitHub (using webhook events), and through Runtime Manager and the TIBCO Admin Console as well.
- Wrote technical design docs and interface specs for new event-driven integrations. Took part in design and code reviews and mentored junior team members on best practices. Used API Designer to design, document, and mock MuleSoft APIs.
- Designed the data architecture and used DataWeave to build a canonical data model that combined customer data from SAP and IAM into one central Operational Data Store in Cassandra. Set up Batch Processing to make the ETL loads to Salesforce more efficient.
- Built a company-wide TIBCO tool that automatically creates ServiceNow tickets, cutting manual ticket assignment by up to 90%. Exposed it as an API that any business app can call.
- Built the back end in TIBCO BusinessWorks that replaced part of the legacy mainframe train scheduling app, cutting legacy system use in the Integrated Transportation Management department by up to 20%.
- Worked daily in Agile/Scrum teams to build, support, and tune high-volume ESB hub-and-spoke integrations and pub/sub flows across test, UAT, and production.
