Andrey Rudenko
Software Engineer at Databricks
Berlin, Germany
Summary
🤩
RockstarAndrey Rudenko is a seasoned software engineer with 18 years of experience building high-performance backend systems, currently based in Berlin and working at Databricks. His career spans startups and large tech firms—Neon, JetBrains, Yandex and others—where he focused on distributed systems, databases and scalable event-driven architectures. He has deep PostgreSQL and proxy/cache expertise demonstrated by contributions to Neon’s serverless Postgres proxy and connection caching, and earlier work on fiber-aware async tooling in the Ruby ecosystem (em-synchrony). Andrey has led engineering teams and served as CTO, pairing hands-on systems design with product-minded leadership. He brings a pragmatic polyglot background (Ruby, Clojure, JVM ecosystems) and a track record of optimizing connection management and asynchronous database interactions at scale. Colleagues will find him comfortable both refactoring core libraries and shipping production-grade database infrastructure.

Back-end Developer & Database EngineerContributions:24 reviews, 16 PRs, 36 pushes in 1 year 3 months
Contributions summary:Andrey's commits primarily focus on enhancing the Neon database proxy, specifically related to handling and processing PostgreSQL startup parameters, implementing connection caching mechanisms, and optimizing options management. The user added features to pass Neon-specific configuration options to the control plane and compute nodes, and incorporated these options into cache key generation. Additionally, the user made significant changes to the `compute_ctl` tool, implementing new API endpoints to fetch database schemas and roles, leveraging PostgreSQL and compute infrastructure.

Contributions summary:Andrey primarily contributed to enhancing the `em-synchrony` project, which provides fiber-aware replacements for standard Ruby threading objects and ActiveRecord integration. Their work included implementing a fiber-aware Mutex and integrating ActiveRecord with the event loop, allowing for asynchronous database operations. Several commits modified core components, particularly in `lib/em-synchrony` and related ActiveRecord adapter files. These changes focused on ensuring proper synchronization and connection management within the event loop environment.
