Senior Test Automation Expert with more than 10 years experience in test automation, especially within the performance testing area. Hands-on experience with performance test simulations, analysis, tuning and monitoring. Design and implementation of fully-automated regression load tests with almost any (performance) test automation tool. Interested in (performance) test automation for any kind of system e.g. web services, web GUI, Oracle Forms, using any tool. Practical experience in Agile and traditional software development methods. Identification of potential performance risks on all levels. Design, development and execution of performance load tests for each identified performance risk.
I have been working in Agile teams for the last 3 years. This consists of collaborating and sharing automated (load) test results with developers, architects, technical application managers and all other stakeholders. The final goal is to share results quickly to help them understand which errors have occurred and what needs to be fixed. Experience also with integrating automated (load) test solutions with continuous integration servers, so that test can be triggered on each and every build. Last but not least, always providing easily understandable test reports that can be understood by anyone.
I am result-driven and I have a pragmatic and flexible attitude. Colleagues describe me as accurate, creative, getting things done, result-orientated, honest and reliable.
My Professional Background
2015 January - Present
2015 - Performancetest Expert
Independent (performance) test automation expert
I provide independent consultancy (and engineering) on all aspects of performance testing in Agile/DevOps - Teams. Specialties: effective automated performance testing for any system, using any tool. (Loadrunner, Neoload and Silkperformer). Also more then 4 years experience with functional test automation (QTP, HP Business Components, UFT and Selenium).
Experience in several aspects within the performance testing area, including:
Test automation and performance tests will be integrated more and more in the near future. I reuse a (subset from the) functional test suite that allows the client to create the performance test. Moreover, rich Ajax-based internet applications often require ’single user‘ performance tests as well, to validate the client end-to-end response time (e.g. browser memory leaks and resource usage on each and every device).

Test Automation engineer
Job DescriptionTest Automation Engineer
Test automation Engineer within a large financial company. I designed an automated regression test suite enabling thorough regression testing of the system with each change. This was a really complex financial mortgage system with more than 100 screens (Web - HTML, AJAX and CSS). All screens where automated within QTP (UFT) as scripted components (together with HP Business Process Testing (BPT)). BPT provides the framework for designing and developing reusable test components and flows, enabling non-technical subject matter experts to build and execute tests quickly. Business Process Tests were defined centrally within the HP Quality Center/ALM. Both manual and automated tests could be run. I also developed a procedure to provide test sets easily with test data (excel export/import).
Implemented an automated test-mindset within the test department. Focus shift from manual testing to automated testing.
Senior Engineer for performance testing, assisting other project members with infrastructure and application performance tests. Monitored and analysed (evaluated) overall system capacity during end-to-end load tests. Worked closely with the application development department, the architect and the infrastructure group to solve performance issues found during tests.

Technical Support Engineer
Job DescriptionTest Engineer / Technical Support Engineer
During this role, I worked within the Research and Development Department of a large IT organisation. Managing software development environments was one of the main tasks. Software Configuration Manager/Build Master. This role consisted of supporting developers in the software configuration management area, e.g. management of artefacts (source code) with a version control system (ClearCase). Also responsible for an isolated acceptance environment, so that (unit) tests ran automatically after each build every night. Here I also gained my first experience in performance-testing, creating test scripts and running tests to check software reliability and robustness. Reported and communicated defects and issues to developers and other stakeholders. By working closely together with a development team, I clearly contributed to improving the software quality. It was already in a type of agile structure, delivering working software every day.System Administrator
During this period, I worked for several companies, fulfilling several roles, which provided me with broad experience in different market branches, IT - Software development companies, government bodies and chemical industries.
In my first role as a system administrator, or ‘Sysadmin’, I was responsible for the configuration and reliable operation of computer systems, especially multi-user computers, such as Unix and Windows servers. Ensuring the uptime, performance, resources and security of the computers and managing the needs of the (end-)users. As a system administrator, I installed or upgraded computer components and software and provided routine automation; maintained security policies; troubleshooting; problem-solving, frequently under various types of constraints.Network Administrator
As a Network Administrator, I was able to quickly and correctly diagnose what the problem was and how best to fix it. Network administrators are generally mid-level support staff within an organization and do not typically get involved directly with users. Network administrators focus on network components within a company's LAN/WAN infrastructure ensuring integrity. Depending on the company and its size, the network administrator may also design and deploy networks.
Network Administrators are often involved in proactive work, such as: network monitoring, testing the network for weaknesses, evaluating and implementing network management software and monitoring network traffic and bottlenecks. My service-minded approach meant that I was successfully able to handle all tasks mentioned above, resulting in satisfied clientsSupport Engineer
During this period, I worked for one of the most innovative software companies as a Technical Support Engineer. I solved specific problems with the first midrange Linux/Unix multi-user computer systems, using Unix/Linux command line skills. Installed and deployed (network) operating systems and did troubleshooting of all types of environment issues. In other words, I really listened to the clients in order to truly understand their problem or question and helped them solve it.
