Simon Stewart contributed to SeleniumHQ/selenium and grpc/bazel-central-registry by modernizing build systems, improving dependency management, and enhancing code maintainability. He upgraded Bazel configurations, introduced BOM-driven Java dependency management, and stabilized CI workflows, using technologies such as Bazel, Java, and Python. Simon implemented immutable data structures in core modules to increase runtime safety and prevent unintended mutations, while also aligning build tooling with evolving ecosystem standards. His work included patching protobuf-related CI failures, updating Bazel rules for future compatibility, and refining build hygiene. These efforts reduced configuration drift, improved reproducibility, and established a robust foundation for ongoing cross-language development.

Summary for 2025-09: Implemented the Contrib Rules JVM Bazel Module 0.30.0 for grpc/bazel-central-registry, updated dependencies, patched rules for future Bazel compatibility, and configured linters and build targets to preserve JVM ruleset integrity. Focused on build hygiene and long-term maintainability to reduce risk across consumer repos.

August 2025 (SeleniumHQ/selenium): Focused on modernizing build tooling by upgrading the Bazel dependency resolver and simplifying overrides to improve build reliability and maintainability. Upgraded rules_jvm_external to version 6.8, updated MODULE.bazel, and migrated from a git_override to a single_version_override to leverage latest features and bug fixes in rules_jvm_external. The change reduces configuration drift and enables smoother iteration with up-to-date Java toolchains and ecosystem fixes.

May 2025 - SeleniumHQ/selenium: Delivered key features and fixes across the Java dependency lifecycle, ChromiumDriver safety, and Bazel-based build tooling. Implemented BOM-driven Java dependency management in MODULE.bazel and updated BOM versions (OpenTelemetry, Netty, JUnit). Netty 4.2.0.Final update was intentionally omitted due to a Java module generation bug. Hardened ChromiumDriver by returning immutable collections to prevent external modification, increasing runtime safety. Updated Bazel JS/TS rules to the latest Aspect rules to leverage new features and bug fixes, enabling smoother cross-language builds. These changes reduce dependency drift, improve stability, and demonstrate strong cross-functional skills across Java, JS/TS, and Bazel ecosystems.
