Summary
🤩
Rockstar🎓
Top SchoolEthan Zhang is a program director and engineering executive with 11 years of experience designing and scaling large distributed data platforms, currently leading IBM’s watsonx.data initiative out of Houston. He combines deep academic foundations—a Ph.D. in Computer Science—with hands-on backend engineering, having driven query execution and lakehouse engine work across IBM, MongoDB, InfluxData, and Volt Active Data. Ethan is an active open-source contributor to high-impact projects like InfluxData’s Flux and InfluxDB, where he improved language interpreter semantics, testing, and runtime tracing for production query workloads. He excels at bridging research and product: migrating parsers, modernizing dependencies, and implementing read/window aggregation and opentracing to make large-scale analytics more reliable and observable. Colleagues describe him as a technical leader who still codes on core systems and prioritizes test coverage and robustness in complex distributed environments. His background suggests an uncommon blend of academic rigor and pragmatic system-level contributions to popular observability and lakehouse tooling.

influxdata/flux
Aug 2019 - Nov 2020
Flux is a lightweight scripting language for querying databases (like InfluxDB) and working with data. It's part of InfluxDB 1.7 and 2.0, but can be run independently of those.
