Developer Management Console and database layer

Nedstat B.V.

Partnership; 1-10 employees; Professional Training & Coaching industry

July 2008May 2010 (1 year 11 months) Amsterdam Area, Netherlands

As a Java developer I was responsible for maintaining and improving the Management Console (MC, see below). This web application is used as a front-end to the database used by Sitestat, our web analytics package. It is used within the company by several departments and runs on Tomcat 6. It has been built using Hibernate and the Spring framework and makes extensive use of the MVC model.
I maintained our database layer using Hibernate Tools and Freemarker templates. This database layer is used by both the MC and our Sitestat core services.

Developer Custom Made Reports

Nedstat B.V.

Public Company; 51-200 employees; Internet industry

August 2007June 2008 (11 months) Amsterdam Area, Netherlands

After moving to Amsterdam Zuidoost, I was relieved from my TAA duties and made fully responsible for programming Custom Made Reports (CMRs) for our clients and managing my department. This included making sure deadlines were met, reporting to Sales about the current status of requests and pushing down delivery times.
At this time we also moved away from the custom Nedstat Query Language and Post-Processing towards Java. This meant we had to convert and check all custom report items ever written for our clients. As a bonus, all our items are now versioned using Subversion and built using Apache Ant through TeamCity.

Technical Application Administration

Nedstat B.V.

Public Company; 51-200 employees; Internet industry

May 2006July 2007 (1 year 3 months) Amsterdam Area, Netherlands

My main responsibility was programming Custom Made Reports (CMRs) for our clients. CMRs were created in the custom Nedstat Query Language (NQL) and Post-Processing language.
I was partly responsible for maintaining the software on an application level for Sitestat 5, our web analytics product. Responsibilities included monitoring the web servers and MySQL servers with Sysmon and acting on errors.
Me and a colleague were responsible for the TAA part of software releases of the Sitestat product.

Privately Held; 501-1000 employees; Electrical/Electronic Manufacturing industry

April 2000May 2006 (6 years 2 months) Amsterdam Area, Netherlands

I was responsible for setting up the Corporate Helpdesk in April 2000.
My responsibilities included giving technical support by telephone, fax or e-mail to corporate customers and resellers in both Dutch and English. Support should be given regardless of operating system or hardware. Operating systems encountered included Windows, Mac OS and
several of the Unix flavors.
On the side, I developed, maintained and gave product trainings to sales employees and resellers.
I developed and maintained tools and cooperated in projects. Among other things: a web-based helpdesk e-mail system (WebHM 1.2 and 2.0, see below), a customer monitoring system (Mon, see below) and automating common tasks.
Part of my responsibilities was to maintain the FreeBSD support server. Among other things: create accounts for new employees, upgrade the server, generic maintenance, upgrade the ports and configure systems and software. This was later on handed over to OSS.
As a Corporate Helpdesk agent I also installed hardware at customer locations.

Employee second line Technical Helpdesk

EuroNet Internet B.V.

Partnership; 1-10 employees; Professional Training & Coaching industry

January 2000March 2000 (3 months) Amsterdam Area, Netherlands

As a second line technical support employee I was responsible for supporting, training and coaching first line employees. I had to make sure their level of support was at our company standards and update their knowledge whenever that was needed.
We also had to solve open tickets from first line employees, and train these employees to be able to solve these tickets themselves.
One of my personal responsibilities was to develop new tools and extend or revise the current tools for improvement of support.

Gillis J. de Nijs' Projects

  • Management Console 2.0

    Team Members: Gillis J. de Nijs

    In order to improve the reliability and speed of the Management Console 1.0 we started work on a new version, from scratch. That has been done using ICEfaces, a J2EE Ajax framework for developing and deploying rich enterprise applications. We converted our entire Hibernate layer to a JPA annotated version. It runs on Tomcat 6. The project was eventually abandoned due to time constraints and other projects that took priority.

  • Management Console 1.0

    Team Members: Gillis J. de Nijs

    The Management Console (MC) is a web-based database front-end that is used to add, change and delete clients, sites, users, report items, etc. in the Sitestat database. The application has been developed as a Maven project using Spring and Hibernate and runs on Apache Tomcat 5.5. My responsibility was mainly updating the Hibernate layer that we use through-out the company and fixing issues in the tool itself. That also includes keeping the software up-to-date for the current version of the database model.

  • WebHM 2.0

    Team Members: Gillis J. de Nijs

    WebHM is a web-based tool to receive and process customer e-mail. E-mail is delivered in several mailboxes by means of a filter setup. Users (helpdesk agents) can login using HTTP authentication and authorization. All actions are logged by user name, for review by supervisors later on. Users can archive, reply, forward or move e-mail to a different inbox. It’s possible to add an answer to an e-mail and save that, and then move that e-mail with prepared answer to a different department. This can be useful when a customer has both a technical and an administrative question. This is a complete rewrite of the previous version. Since everything is now stored in a MySQL database, it’s easier to maintain. An administrator interface is available to add e-mail boxes, users, filters and access levels. The system has been built in Perl, with a MySQL database backend, and uses mod_perl.

  • Mon

    To be able to monitor Versatel Business ADSL customers on the Corporate Helpdesk, a colleague and I built a system that performs ping-tests to check whether customer lines are up or down, and to check their latency. This data can then be visualized in graphs. When the line status changes from up to down, an e-mail is sent to the helpdesk. The system has been built in PHP, with a PostgreSQL database backend, and uses fping and rrdtool.

  • Quiz

    For the EuroNet and Wanadoo helpdesk, a colleague and I built a website to enable supervisors to test their agents. This way it became more evident which agents lacked what knowledge and could use some extra training in specific areas. Test results are archived to be able to generate statistics later on. To maintain the system, an administrator interface is available to add users, questions and tests. The system has been built in PHP, with a PostgreSQL database backend.

  • Monkey Tool

    Team Members: Gillis J. de Nijs

    On the EuroNet and Wanadoo helpdesk, we had several systems containing information about our ADSL customers. I built a web page to combine the output of those systems. That way, users could check all settings, from all different systems using just the account number and one mouse click. The system has been built in Perl.

  • WebHM 1.2

    Team Members: Gillis J. de Nijs

    WebHM is a web-based tool to receive and process customer e-mail. E-mail is delivered in several mailboxes by means of a procmail setup. Users (helpdesk agents) can login using HTTP authentication. All actions are logged by user name, for review by supervisors later on. Users can archive, reply, forward or move e-mail to a different inbox. It’s possible to add an answer to an e-mail and save that, and then move that e-mail with prepared answer to a different department. This can be useful when a customer has both a technical and an administrative question. The system has been built in Perl, and uses some PHP and procmail.
