Worked on the pulumi/pulumi-java repository to deliver parallel deployment support for the Pulumi Java SDK, focusing on enabling scalable and concurrent execution of Java-based Pulumi programs. Refactored the deployment context by replacing static fields with thread-local storage, ensuring safe context management across threads. Introduced ContextAwareCompletableFuture to propagate deployment state through asynchronous operations, addressing challenges in concurrency and context propagation. Applied a targeted context-awareness bug fix to maintain correct state across async boundaries. Leveraged Java, asynchronous programming, and concurrency techniques to improve throughput and reliability, laying the groundwork for more robust and performant deployments in cloud infrastructure automation.
