Robert W. Baird (consultant)

Developer/Solution Architect 10/2013– 04/2014

Redesigned and rewrote the client’s Standing Letter of Authorization business process. When customers need to transfer money between accounts, a signed Standing Letter of Authorization is required to be on file. The current process would require one or more signatures for each instruction, (ACH, Check, Intra-Household, Journal, or Wire), that is added to an account. In some cases, this would mean up to 100 forms to sign for one customer. In order to reduce paperwork, the entry and print forms were redesigned so that any number of instructions can be added to an account, and only one set of signatures is required for that group of instructions.

Modified the client’s existing business processes in order to accumulate information when forms are rejected at management review points. Currently, the client gathers no metrics when forms are rejected. The processes were modified so that the rejecter must select one or more reject reason codes and possibly enter a note when rejecting a form. This information is saved to the form. By doing so, reports can now be generated providing metrics on rejections with who/why/when/how many information. Given these reports, the client can make appropriate training and business process adjustments. The business processes include Check Request, Account Opening, Automated Clearing House, Advisory Workflow Application, Standing Letter of Authorization, Automated Client Account Transfer, Wire Transfer, and Margin Option.

Created forms to monitor the Liquid Office environments. Liquid Office includes an API which provides runtime metrics for SQL response times and various JVM health metrics. The new forms allow the client to monitor these metrics on a real-time basis.

Performance-tuned some business processes, which, in one case, decreased form open time from ~45 minutes to ~5 seconds.

Served as the only Developer for a J2EE project

Developed several classes and test classes in order to test cluster set-up and fail-over conditions.

Analyzed the existing EJB deployments in the enterprise architecture to determine whether they could be clustered, and what the impact would be to make them clusterable.

JAVA, WEBLOGIC, UNIX AIX, WIN2000

Application: Merchandise Analysis API

Several pieces of the current application were rewritten in Java and deployed as EJB’s on a Weblogic server.

Assisted team in understanding and using the new persistence layer.

Also trained the team on how to write test classes using junit. Eventually, we developed a new API for external applications.

JAVA, WEBLOGIC, UNIX AIX, WIN2000, ORACLE, DB2

Application: Merchandise Analysis Retek conversion

The current application had to be converted to use a new source of data for some of its queries.

This data was now contained in a purchased software package, which required the use of MQ Series to make the queries.

Worked out the communication bugs introduced by the external system’s API, and trained the rest of the team on how to issue the MQ Series calls.

MQ SERIES, C, ENTERA, UNIX AIX, WIN2000, POWERBUILDER, ORACLE

Application: Media Services System

Added several enhancements so that the application could now support classified advertisements.

The current system was used to generate orders for print and catalog advertisements.

The enhancements allowed the Human Resources department to utilize the application to place classified advertisements for employment directly to newspapers or periodicals via fax or electronic document format (XML).

C, ENTERA, UNIX AIX, WIN2000, POWERBUILDER, XML, ORACLE, DB2

Application: Promotional Pricing System

Redesigned and rewrote the client’s TradeRoute RV application, including defining the object hierarchy

and all base classes, record locking mechanisms, and process flow including multi-threading and interprocess communication.

The application was an electronic document handling system used by the RV industry.

It allowed RV dealerships and suppliers to enter documents such as purchase orders and warranty claims, and transmit them automatically as EDI type transactions to the appropriate supplier. The supplier would use the application on their end to import the document transactions, and they

could generate the appropriate response transaction and send it back to the originator.

The originator could then use the application to import the response transaction in order

to determine the status of the document.

Developer/Designer 10/1998– 03/2010

Application: Provider Audit Tracking System

Involved in all aspects of the application.

The application was designed to replace an existing single-user DOS-based application. The new application supports multiple concurrent users. The system is used to maintain the workload assignments of audit teams, and to reopen and close audits for health care providers.

The system features processes to synchronize the network database (Sybase), with the single user application files (dBase). By doing so, other departments that still utilize the old DOS-based application may still do so, and they will see the most up to date information.

This system also included a smaller security application, which was needed to set up the appropriate user group security levels and information access.

These security groups were used to limit users to the appropriate windows, data, and functions in the Provider Audit Tracking System application.

Main development focus was on the server-side processing.

Wrote the majority of the JAVA servlets, which included dynamic HTML creation, and information saving by means of flat files on a Solaris server.

Defined several proprietary HTML tags for the client which were used in template files in order to populate dynamic HTML with information from saved fiat files and an ACCESS database.
