Experience

General Ledger & Accounts Payable Applications

A suite of middleware integrations built using MuleSoft, to integrate the accounts payable and accounts receivable transactions from Guidewire (customer source system) to PeopleSoft database tables. These applications were designed with a non-functional requirement of reliability with a zero message loss tolerance and zero tolerance for duplicate processing. Integrations were built with transactional capabilities with JMS messaging as the main transport that triggers the processing of the applications.

Integration Proxy Application

A middleware application developed to decouple a SaaS application from a legacy integration platform. This application was written in Mule 3 with some Java customization to connect to a SonicMQ broker. The business proposition of this application was to reduce the time and resourcing it takes to restore business service after failure.

Mule Flow Control

This was a Jenkins job created to automate the control of a Mule process flow in an on-prem application network. I designed and built the pipeline job using Jenkins and Groovy. This business value of this job was to provide a method of suspending JMS queues from processing messages in a mule application.
