Rockstar🎓
Top SchoolMick Wever is a Principal Architect and engineer with over 20 years of hands-on experience designing and implementing distributed data platforms, specializing in Apache Cassandra internals and low-latency, event-driven microservices. As an Apache Software Foundation member, Cassandra committer and PMC member — and former PMC Chair for both Tiles and Cassandra — he blends deep open-source governance with practical engineering at scale. He has driven storage and tracing improvements in notable projects like Zipkin and OpenTracing and recently built a Cassandra vector store for Spring AI, showing a knack for adapting core database tech to modern AI needs. His career spans global roles at The Last Pickle, DataStax and IBM, where he shaped Cassandra-based offerings and enterprise data products. Trained in computer science and physics, he applies scientific rigor to performance tuning and schema design while mentoring incubation efforts for projects such as SkyWalking and Otava. Outside code, he’s an avid outdoorsman — an indicator of the endurance and focus he brings to long-running distributed systems work.

OpenTracing API for Java. 🛑 This library is DEPRECATED! https://github.com/opentracing/specification/issues/163
Role in this project:
Back-end Developer
Back-end DeveloperContributions:22 commits, 42 PRs, 92 pushes in 10 months
Contributions summary:Mick primarily focused on refactoring and simplifying the OpenTracing Java API. Their contributions involved removing deprecated components and consolidating functionalities, specifically related to `TraceContext`, logging, and span creation. They introduced a builder pattern for creating spans and integrated the AutoClosable interface for improved resource management. Furthermore, the user added an example tracer-independent implementation and integrated it with a Brave Bridge for OpenTracing to Zipkin.
