About Ilker

I help data teams design and ship production-grade data systems — from batch pipelines to cloud infrastructure — that are reliable, scalable, and maintainable.
With 10+ years of experience across tech, banking, insurance, and gaming — including time at Yandex, Swiss Re, and AON — I bring both analytical depth and engineering rigour to every project. I've worked across the full data stack: designing SQL models for financial reporting, building and automating batch data pipelines, migrating data warehouses to the cloud, and setting up Kubernetes clusters with full observability.
What sets me apart is that I think in systems. I don't just build pipelines — I make sure they fit into the broader architecture, are easy to operate, and scale when needed. I'm equally comfortable writing Go services, modelling data in SQL, or managing infrastructure with Kubernetes, Pulumi, and Helm.
Typical projects I take on: data pipeline design and implementation, cloud data infrastructure setup, data warehouse migrations, CI/CD for data platforms, and analytics engineering.
