Ash Coleman

A progressive type, Ash focuses her efforts within technology on bringing awareness to inclusion of women and people of color, especially in the Context Driven Testing and Agile communities.

An avid fan of matching business needs with technological solutions, you can find her doing her best work on whichever coast is the sunniest. Having helped teams build out testing practices, formulate Agile processes and redefine culture, she now works as an Engineering Manager for Credit Karma and continues consulting based out of San Francisco.

I love building things on Linux, especially in clouds. I like reliable infrastructure as code, descriptive provisioning tools and statically typed programming languages. I see it as my destiny to help people achieve serenity using DevOps.

My purpose in life seems to be trying to outsmart computers. I’m really bad at it most of the time.

Nicolas Steenhout offers real-world insight into everyday accessibility issues.

His work began in the mid-‘90s. As a developer, he was approached by clients facing challenges not yet part of the public consciousness. On the emerging web, accessibility hurdles were keeping people with disabilities from engaging with a technological revolution. As Nic began championing web accessibility, he transitioned into the non-profit sector where he collaborated with people with a wide variety of impairments.

Today, Nic continues his accessibility work as an independent consultant for private businesses and non-profits. Having worked on three continents, he’s engaged with thousands of individuals with disabilities.

I work at Badoo as Senior iOS QA engineer. Before moving from Minsk to London and joining Badoo in 2018, I got some experience on various outsourcing projects. They included mobile applications, complex web projects and some backend testing.

All started a few years ago when I decided to drastically change my field of occupation. Thus after calm land management I plunged into the raging sea of software testing.

Now, I try to actively participate in different testing-related events, meet new people and benefit from knowledge-sharing. I spoke at several international conferences and local meetups. Also I like to challenge myself at various software testing competitions (like and Testathon).
