Projects:
CheckVision Cheque Imaging Systems
- Solve reliability issues with a cheque image management system that grew to have two queue managers, 2 distinct sets of image processing services,
a db2 database, bidirectional SFTP and CONNECT:Direct connections, and 2 Java based services for each of 7 different financial institutions.
- Developed software and procedures for cheque imaging servers to allow all of those services to be coherently monitored through Nagios and restarted
through a Capistrano/Webistrano web-based interface. This allowed much of the day-to-day administration of these servers to be off-loaded to QA engineers,
freeing up implementation analysts on our team.
Symcor Data Exchange
- Created file mover routes for complex data flows from financial institutions, insurance, and healthcare clients, to our work scheduler, bulk print servers, and archives.
Options supported included CONNECT:Direct with EBCDIC-to-ASCII conversion, GPG decryption, and SFTP. Infrastructure included RedHat clusters to give HA capability to our extranet
DMZ nodes, intranet DMZ nodes, internal nodes, and disaster recover nodes.
- Modified ACLs, archive scripts, logging scripts, and cleanup scripts to keep landing zone folders from overflowing and keeping response time to incoming files high. Chose between trigger file and temp folder mechanisms
to guarantee that only complete files were processed or re-transmitted.
- Supported the development and testing of a new version of our system based on Apache Servicemix and Kafka. Wrote and tested new Camel routes to support new data flows.
DSS Framework
- Migrated build process based on ant scripts and a command-line interface to Jenkins.

eXtreme Scale servers, 2 haproxy servers, 2 nginx servers, 2 WebSEAL
servers, 1 Tivoli policy and authorization service server, and 1
deployment manager.
- Improved build and deployment scripts. This removed inconsistencies
between environments and decreased deployment times from half a day to
40 minutes.
- Edited Python scripts to support automated deployment of
applications to WebSphere, user record verification, and command-line
queries against eXtreme Scale.
- Migrated our environments from laboratory WebSEAL servers to WebSEAL
servers in DMZ. Configured certificate-based connections between
WebSphere and Tomcat servers and Tivoli Access Manager Authorization and
Policy Servers.

- Wrote two different Java apps with Struts in the front-end, and
Hibernate with Oracle in the back end to administer users simultaneously

Documentum Business Objects Framework and 3rd party Java-to-OLE bridge.

- Supported SharePoint: performed restores from databases, responded to and fixed slowdowns and outages.
- Created and updated comprehensive monitoring plan for both MS SCOM
and Tivoli Monitoring for 7 different systems composed of 31 servers
