About
I build data platforms that hold up in production.
I'm a Senior Data Engineer with 6+ years delivering scalable, production-grade data platforms across financial services, mobility, telecom, and real estate. I work end-to-end — architecture, DataOps, data modeling, and AI-augmented engineering.
Today at Garanti BBVA Teknoloji I own financial and sustainability reporting pipelines serving BBVA group, domestic regulators, and internal management — and built an AI-powered metric discovery platform that turns schema exploration into a self-serve capability. Before that, at FREENOW, I engineered real-time pricing infrastructure on Kafka and Flink and helped drive a company-wide Data Mesh migration.
