"Using DevOps to Grow"

Hi, I’m Maaike. Like many other people in testing, I accidentally became a tester. I got an opportunity to test for the business in the “User Acceptance Phase” and found out that I love asking “why” and trying to find out how systems work. This was 10 years ago, but it feels like a lifetime ago!

In these 10 years, I’ve seen testing and the role of the tester change. A lot. I had to change as well. But some things remain the same: my love for asking questions and finding out how systems work.

In the testing community, I’m known for my work in the exploratory testing and critical thinking domain. It’s my mission to make more people aware how our work is shaped by our own cognitive biases and (lack of) critical thinking. I try to fill in the role as tester as broad as possible because I don’t like to be put in a box. I’m a tester, but I can do so much more than that.

I am Mirjam and I started programming at the age of eleven on a Schneider CPC 464 in Locomotive BASIC. While programming has been a hobby ever since, my career didn’t start in that field at all. I was an accountant, management assistant and office administrator. Later I started to work as a dogtrainer with main focus on behavioral issues. After many years working with people and their dogs I changed my career for the second time and became a frontend developer.

Patricia is a programmer who has worked mostly in C++ and Java. She has spent her career continuously delivering from the same code-base to a large user base, from working on two browsers (Opera and Vivaldi), to working on embedded telepresence endpoints for Cisco. She is focused on the maintainability and flexibility of software architecture, and how to extend it to provide cutting edge user experiences.

Her focus on the end users has led her work more and more toward privacy and security, and she has recently started her own company, TurtleSec, hoping to contribute positively to the infosec and C++ communities. She is also involved in the #include<C++> organization hoping to improve diversity and inclusion in the C++ community.

Test specialist turned Agile Coach turned Programmer. Loves exploring the field of Software Development from different perspectives to uncover the mechanisms at play in between technologies or humans (or technologies and humans).

Amanda Nobil is a Sr. Staff Test Engineer at Medidata Solutions, Inc. She started out in public policy and administration as well as law and legal studies, but began what she thought would be a “rebound relationship” with testing after moving to the San Francisco Bay Area. Many years later, she finds herself instead as part of a loving, if cheeky, union with code based on mutual respect and admiration.

Amanda often finds herself in a number of roles within a role: Investigator, Doctor, and Psychologist to name the most prominent few. However, she is of the opinion that such is testing and such is life.

When not uttering either the words, “Wait, but why?” or “Let’s explore that feature/thought/statement/etc. a little more,” you can find her observing (lurking?) on Twitter or thinking a lot about testing, software, and her place in that realm.

Bernardo Guerreiro, from Portugal and living in London, is a Software Engineer with a focus on Release and Testing. He has a wide range of experiences, ranging from device automation to testing of distributed systems, both from a frontend and backend perspective. In particular, he has solid hands-on experience of implementing Contract Testing at a large scale on a micro-services architecture. Recently he has been very interested in how DevOps can complement the role of Quality Assurance in an organisation, and in trying to solve company-wide problems by being involved in architecting and building infrastructure and tooling to support multiple teams. He currently works for Auth0, an industry leading identity as a service provider.

On a personal note, he likes to spend his spare time with his partner and friends, is an avid traveller, and now enjoys card games as a hobby (having formerly played some of them on a professional level).
