I'm building ScopeDB during the day as its co-founder.
I help open-source communities grow and serve as a Board Director and Incubator Mentor at the Apache Software Foundation (ASF).
ScopeDB is a serverless database that turns live event data into real-time insights, with schemas that adapt as the data changes.
FastLabs brings together our work on fast Rust crates, from tracing and logging to error handling.
My Apache work focuses on Rust infrastructure: Apache Asyncband (incubating) for async coordination, Apache DataSketches for Rust for streaming sketches, and Apache OpenDAL for unified data access.
