Data Systems — Product Strategy — Analytics

Anastasia Terzidou

I design data systems that businesses rely on for real decisions.

Bridging product, data, and operations to build reliable reporting and revenue systems.

Focused on system reliability, data integrity, and decision-ready analytics for internal platforms and revenue environments.

About

Shaped by systems thinking, product contribution and data-driven problem solving.

I design and improve internal data and reporting systems used in real operational environments. My work focuses on turning complex data flows into reliable tools that teams can actually use to make decisions. I operate at the intersection of product, data, and system logic, translating business needs into structured, usable functionality.

Systems Thinking

I design systems that remain stable, scalable, and consistent under real operational pressure.

Product Contribution

I define what should be built, why it matters, and how it aligns with business goals.

Analytical Rigor

I ensure data is validated, consistent, and reliable before decisions are made on top of it.
