Gokhan established Data Science at Attest. He built our core DS/ML infrastructure and many of the first AI products we introduced.

Instead of getting lost in a sea of tools or approaches, he focused on what truly mattered for our business and delivered value quickly after joining.

Gokhan was fun to work with, brilliant and informed on the topics he worked on, and created a lasting platform still in use today.

I'd hire him again in a heartbeat.

Gokhan is that rare find - a technical expert who actually speaks business language.

He has an exceptional talent for understanding what leadership teams really need and translating complex AI concepts into solutions that deliver real value.

Working with him is refreshingly straightforward and productive.

I had the opportunity to work with Gokhan on combining quantitative and qualitative research data to create a holistic view of the customer. His ability to integrate broad data sources and extract clear, actionable insights was invaluable.

He is able to distill complex academic concepts and methodologies into clear, accessible insights that everyone can understand and apply. He bridges the gap between nuance and practicality, making sophisticated ideas approachable for all and working within fast-paced businesses.

Gokhan's methodological rigour combined with practical industry experience brings a rare perspective to computational social science problems. His expertise in both Python and R environments, coupled with his LSE background, ensures he understands the theoretical underpinnings of research, while his industry experience brings valuable insights about scalability and deployment.

For any institution looking to advance their computational social science capabilities with someone who truly understands both the methodological demands and technical implementation, I would strongly recommend Gokhan.

Gokhan has an exceptional talent for building world-class data teams. He goes beyond hiring for technical proficiency, seeking out individuals who bring a unique combination of curiosity, collaboration, and the courage to innovate.

In a discipline often defined by numbers and algorithms, Gokhan never loses sight of the human element. He recognises that behind every dataset lies individual potential and ambition. I enthusiastically recommend Gokhan to any organisation seeking a visionary leader who knows how to unlock both data and human potential.

Gokhan is a brilliant data-driven professional who is very customer focused. He is smart, driven, and easy to work with.

He would be a valuable asset to any firm that is focused on data analytics and insights.

Gokhan generated great impact leading our data, data science and AI work.

A pleasure to work with, and full of ideas, Gokhan turns 'conceptual' into 'valuable' across a range of domains and ideas.

What stands out about Gokhan is how easily he connects technical depth with business priorities.

He doesn’t just build data strategies, he makes sure they’re practical and aligned and drive the outcomes that matter. He works closely with teams, demystifying complex topics, and helps turn data into a real advantage for the business.

Gokhan bridges the gap between strategic goals and technical acumen in a way I've seen few others do.

He's able to think big picture and execute in the weeds to make sure things actually get done.

Working with Gokhan was a pleasure, since he’s able to make complex technical detail legible to people outside of his discipline.

As part of cross-functional leads team he was always able to help us make sense of complex data, understand its limitations, and make decisions based on a solid understanding of what’s true.
