David Ingraham

Matium, USA

I’m a Senior SDET and QA leader who has built and scaled automation frameworks for organizations ranging from 15-person startups to Fortune 100 enterprises.

I’ve specialized in turning fragile test suites into reliable sources of truth, leading teams through the challenges of automation maturity, and championing “Shift Left” practices that make quality everyone’s responsibility.

As a Cypress Ambassador and active contributor to the testing community, I’m passionate about making testing approachable, innovative, and fun. I love sharing not only frameworks and strategies, but also the stories, struggles, and lessons learned that resonate with testers at every stage of their careers.

Dona Sarkar

Microsoft, USA

Dona believes that you are one experiment away from being your most powerful self at work. And yes, in life!

Currently at her day job, she’s running 100 experiments as the Chief Troublemaker of the Microsoft AI and Copilot Extensibility Program. Her goal is that people all over the world can use Microsoft’s AI and Copilot programs to reason over their OWN data and truly make AI useful for their business.

Dona’s also a keynote speaker (fave audience is corporate leaders like YOU), a multi-published author (it turns out fiction writing is useful in software!),  the owner of the ethical luxury fashion brand called Prima Dona Studios and she has recently become a wine bar co-owner and is studying to be a sommelier.

A few years ago, she was named one of Fast Company’s 100 Most Productive People and Cosmopolitan magazine’s Businessperson of the Year for her multi-faceted (aka weird) life.  And yes, she is always ready to get on a plane and come see YOU.

On Test Automation, Netherlands

I am an independent test automation consultant and trainer. I have been active in the test automation field for some 19 years now, and have worked on software testing and automation solutions across a wide range of programming languages, frameworks and technology stacks.

I’ve also delivered test automation training to dozens of companies and thousands of attendees around the world.

I live in Amersfoort, The Netherlands, together with my wife and two sons. When I am not at work, I like to go for a long bike ride, play a game of chess, or read a good book.
