PROFILE
Oskar Dudycz
Worked on kurrent-io/KurrentDB, delivering core backend features in C# focused on distributed systems and event sourcing. Over two months, introduced a unified VirtualStreamReader architecture, consolidating in-memory stream readers under a pluggable interface to simplify logic and improve testability. Developed a secondary indexing plugin with an abstraction layer for index management, subscriptions, and checkpointing, enabling scalable indexing and faster data access. Addressed concurrency issues by fixing race conditions in the Secondary Index Checkpoint Tracker and corrected integration test logic to prevent infinite loops, enhancing CI reliability. Emphasized refactoring, integration testing, and robust system architecture throughout the development process.

May 1, 2025May 2025 — Delivered a robust secondary indexing framework in kurrent-io/KurrentDB. Introduced a new secondary indexing plugin with virtual readers and an abstraction layer to build, manage, and checkpoint secondary indexes, subscriptions, and processing, with enhanced integration tests. Fixed race conditions in the Secondary Index Checkpoint Tracker and corrected a logical error in integration tests to prevent infinite loops, significantly improving test stability and CI reliability. These efforts establish scalable indexing, faster data access, and safer rollout of index features, enabling stronger business value from analytics and query performance.

Apr 1, 2025April 2025 was focused on strengthening KurrentDB's virtual stream handling with a major architectural refactor that enables flexible and scalable ingestion from multiple virtual stream sources. The Unified Virtual Stream Reader architecture consolidates in-memory readers under a single implementable surface (VirtualStreamReader) with a pluggable IVirtualStreamReader interface, reducing complexity and improving testability.
