Last two years I have been working as a WebSphere MQ expert at Rabobank International (RI) in Utrecht. I joined the Middleware team as third team member. The Middleware team is part of the Unix Support team of RI.
At the start the team consisted of three people, two of them started together at the first of April. During the year the team expanded to five people in December 2009. The team is responsible for all middleware related infrastructure. Most important tools are WebSphere MQ, combined with WebSphere MQ file transfer and Spazio file transfer. Being a member of the middleware team I performed both the day to day support activities (most of the time doing the early shifts as a volunteer in the team) and project related activities.
Involved operating systems, running the MQ and MQ related products, are Unix (Sun and AIX), Linux en Windows.
One of my specialties became setting up the sftp/MQ connections between RI and third party companies. Another achievement was creating a uniform poll-script for all sorts of file transfer over MQ.
In 1995 I became an employee of EDS because of an outsourcing activity of CVI (Centrum Voor Informatieverwerking), a subsidiary of Dutch Railways (NS). EDS is a service delivery company, serving many customers regarding management and support of ICT as a whole (hardware, software, processes and procedures).
I worked for EDS until March 2009.
Within EDS the activities gradually moved from application design and programming tasks towards system management and architecture, especially related to middleware environments.
A choice of the activities during my EDS-years:
2007 – 2009:
Being a system administrator, involved in design, implementation and support of middleware environments;
As an interim team leader, responsible for evaluation of work requests, estimating costs and reporting progress regarding ongoing activities;
Technical activities, mainly related to WebSphere MQ and WebSphere Business Integrator Message Broker.
2001 – 2007:
Involved in the creation of a middleware support team. Afterwards as senior team member active within the team. The team is responsible for the support of middleware environments for different customers of EDS (including 7*24 on-call support). The main product of the portfolio is WebSphere MQ. The support covers the whole area from design, via implementation towards incident and problem management for operational environments.
2004 – 2005:
Part-time team member in a project, responsible for implementation and configuration of Sonic MQ and Sonic ESB.
1995 – 2001:
Application development and application support in VAX/VMS-environments.
I joined CVI (Centrum Voor Informatieverwerking, a subsidiary of Dutch Railways) in July 1990. Before I worked for CVI as an employee of Management Share.
Between July 1990 and July 1995 my activities changed from application design and development in mainframe environment to technical application support in VAX/VMS environments.
The design, development, build and support activities were both for administrative and production management systems. Used tooling and programming languages were COBOL, DB2/SQL, CSP and RPG. Used application development methodology: SDM and JSP.
Between 1987 and 1990 I worked for different customers of Management Share.
In 1987 and 1988 I worked for Philips in Eindhoven as an application programmer. designing and building applications in a mainframe environment. Applications mainly written in COBOL, with usage of DB2 and SQL.
The first part of 1989 I worked at the Rijks Computer Centrum (RCC). The activities consisted mainly of altering existing applications, including system integration tests. All activities were related to COBOL, DB2 and IMSDB/DC on mainframe.
The last job via Management Share was at Centrum Voor Informatieverwerking (CVI, part of Nederlandse Spoorwegen). Main tasks were designing and building applications in mainframe environment with COBOL, DB2/SQL en CSP (Cross Systems Product).
In 1989/1990 I was involved in setting up a CSP-course, for which I acted as a teacher in several classes too.
The start of my ICT-career was at ABN Assurantiën, an insurance company.
After a few internal courses regarding structured programming I worked as an application programmer in mainframe and IBM S36/S38 environments. Program language was COBOL with IMS DB/DC.
