# Dina Matveev
Data engineer building large-scale pipelines and taming unpredictable systems.

## About

Dina Matveev builds large-scale data ingestion pipelines and distributed workflows at mavens by Zynga. She takes unpredictable problems and breaks them down into maintainable systems.

She focuses on scaling complex infrastructure and debugging production failures. Her recent talk breaks down how a hidden Puppeteer memory leak took down a web cluster, sharing strategies to keep headless browsers reliable under heavy traffic.

When she isn't wrangling datasets, Dina is usually at the piano or tracking down the perfect cup of coffee.
