Job Description

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:

Gathering performance requirements

Creating performance test plan

Using cases/click paths, model production usage patterns

Load models, designing tests with proper random test data

Developing/writing robust performance scripts

End-user error detection in case of failure

Code load test scripts with reusable components to reduce script maintenance

Monitoring all application layers during test

Continuous integration - running performance tests during sprints

User story test within sprints

Root cause performance analysis: application code, memory, database, query, network, firewall, Java script, etc.

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).

Also WebGUI-based (also AJAX-based) front-end testing and many other responsibilities. When required, also carried out exploratory testing of test all system ’borders‘. All user stories were tested within the sprints.

Job Description

Test 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.

Job Description

Performance Test Engineer

Worked for a software infrastructure vendor that provides business process management suites (BPMS). A cloud-native BPMS solution that will enable customers to re-engineer key processes as part of their transition to a digital business. I developed a sophisticated performance test approach, which consisted of several tasks, including:

Designing and creating test plans, test data, automated test scripts and test scenarios

Working collaboratively with technology teams and key stakeholders from all disciplines

Executing load and stress tests on all application layers, API and end-to-end tests

Understanding the BPMS platform, applications, architecture and underlying components and technologies

Ensuring systems perform at acceptable performance and resource utilization levels

Installing, configuring and maintaining performance testing solutions and monitoring tools

Working directly with Architects and Software Development Engineers to improve performance and reliability

Another task was to advise clients which hardware they need, sizing advice and how to deploy their system to attain a certain transaction rate/volume. Also implemented Mercury/HP Load Runner/Performance center within a distributed development environment (India / Netherlands).

Job Description

Test 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 clients

Support 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.
