Summary
🤩
Rockstar🎓
Top SchoolJoana Trindade is a software engineer and backend/infrastructure specialist with a PhD in EECS and roughly a decade of industry and research experience spanning Google, Microsoft Research, Intel Optane, MIT, and now Databricks in Berlin. She focuses on resilient data systems, persistent logging, and high-throughput caching layers—work reflected in contributions to influential open-source projects like Noria and ReadySet that improve durability and incremental dataflow performance. Her background blends low-latency financial feeds and large-scale storage infrastructure with cutting-edge temporal graph analytics from MIT, giving her a rare cross-domain perspective on systems design. She has hands-on experience with persistent memory (Optane) and has been involved in research that produced patents and peer-reviewed publications. Colleagues know her for shipping durable backend features that bridge research ideas and production needs.

Feb 2017 - Apr 2017
Readyset is a MySQL and Postgres wire-compatible caching layer that sits in front of existing databases to speed up queries and horizontally scale read throughput. Under the hood, ReadySet caches the results of cached select statements and incrementally updates these results over time as the underlying data changes.
