Pulse is a tiny real-time data streaming framework (mini Flink/Beam) in Rust. Async (Tokio), pluggable operators, state, and I/O. Fast, modular, local-first.
Embedded-first, Arrow-native stream processing engine in modern C++ (C++23). Run SQL streaming pipelines in-process in milliseconds, or submit the same file to a distributed cluster: exactly-once, event time, state as open Arrow data, deterministic replay.
Kafka-compatible streaming demo for real-time birding intelligence: event-time windows, late-event handling, stateful deduplication, hotspot metrics, and target-species alerts.
Demonstrates architectural pattern implementations in Apache Beam (Java SDK) to restore event-time ordering on out-of-order keyed streams.

Cross-engine output validation for event-time streaming pipelines.
PyFlink streaming pipeline: Kafka → 5-minute tumbling event-time windows → per-customer spend aggregation. Handles late-arriving events with watermarks and BoundedOutOfOrderness strategy.
