Vice President

Confidential, New York, New York

Responsibilities:

  • Architect, Lead Developer and Project Manager for several BPM/BRMS 6 web applications that enable the execution of BPM processes and BRMS rules to process messages from external clients via JMS and REST APIs and employing a range of EAI patterns including content-based routing, publish/subscribe; dynamic routing; event-driven consumer. This architecture is being adopted as the global standard for BPM/BRMS cloud applications within Citi. Examples:
  • Seamless: Handles the automated processing of employee invoices for off-hour meals. JMS Messages containing invoices are packaged as XML payload and sent over TIBCO to the BPM/BRMS webapp. The webapp marshals the payloads to POJOs that are then injected into stateful BRMS sessions passed for processing by BPM processes and rules. Results are published in JMS messages. A dashboard UI exposes the BPM processes and rules to business users to give them control over the business logic and processing flow. BAM dashboards provide metrics and reporting. The webapp makes heavy use of the Spring framework - CDI, MVC, JMS, Web, Core - for optimum configurability, portability, and reliability.
  • IEP: Tracks the state of Confidential corporate business initiatives from inception through approval and execution. A secure REST webservice provides BPM PaaS via a select set of endpoints to process JSON messages representing initiative events. The messages are marshalled to POJOs that are injected as facts into stateful BRMS sessions for processing by rules and processes, and then sending a JSON result back to remote REST endpoints. The webservice makes heavy use of the Spring framework - CDI, REST, MVC, JMS, Web, Core - for optimum configurability, portability, and reliability.
