I am Sophia Pfab, a passionate Agile Transformation Consultant and Product & Delivery Partner for Tech Teams with a foundation in Industrial Engineering.

My core focus is creating real value, driving efficiency, and sustainably fostering self-organization and intrinsic motivation within teams—always with a clear outcome-orientation. I thrive on helping organizations and teams establish more effective and long-lasting ways of working.

Patrick Stephens

Patrick Stephens

Over 20 years experience in software engineering, mostly in the defence domain at Thales. The last few years of this were focused on transformation first to containers then Kubernetes.

After Thales I worked on the cloud native team at Couchbase, working on their Golang-based Kubernetes operator. This included producing a custom Fluent Bit deployment for observability needs.

Calyptia (founded by the Fluent maintainers) then approached me to come work with them building out observability products before we were successfully acquired by Chronosphere. I then led the migration of all our infrastructure and SOC2 compliance before Chronosphere was again successfully acquired by Palo Alto. During this period I also became a core maintainer of the CNCF graduated Fluent project, primarily working on Fluent Bit.

I am now running an OSS consultancy for observability called Telemetry Forge leveraging our knowledge as well as working with customers in the defence domain again.

Chris Sellek

Chris Sellek

Chris writes things.

Most of the time, he's writing code as a senior software engineer at his 9-5 working for SAS. Occasionally, usually late at night after his wife and three kids are asleep, it means writing fiction (often in the horror and fantasy space) as he prepares to launch his self-publishing author career.

Chris is passionate about helping people understand new or complex topics in ways that are engaging and entertaining, building software responsibly, and reminding engineers that curiosity and empathy are just as important as technical skill.

An extroverted engineer who genuinely enjoys speaking to a room full of people for 20+ minutes, Chris' presenting style has been described as "modern, with a TikTok flair" -- one of the greatest compliments he's ever received.

When he's not "writing things," you'll find him paying video games, reading fiction, or spending time with his favorite people (the aforementioned wife and three kids). he's also incredibly talented, funny, and a general pleasure to be around. And as an aside, he _insists_ that he did not write this bio.

So Neha made it her mission to help organisations bridge this gap and support women on their journey.

What she has to say may offend you, could provoke you, but will definitely make you think. If you’re looking for a keynote speaker who can talk from authentic global experiences infused with actionable insights, then Neha is your choice.

I make AI decisions board-ready with clear strategy, visible risk controls, accountable owners, and results the P&L can see.
