Add CLI support for interacting with cloud stack configs - where stack configs are managed in the cloud instead of as files in the local project directory.

Improved caching and batching performance of secret encryption and decryption within Pulumi state serialisation. This provided significant reduction in deployment times for projects with many secrets.

Built a testing library for running Pulumi programs within a Go test suite. This was primarily to help with testing Pulumi providers but was also adopted by other teams as it's an unopinionated way to test Pulumi programs. It builds on the Pulumi automation API, but providing sensible defaults and asserts for a testing context.

Allow users to specify exact subnet layouts and sizes when creating a VPC with the Pulumi AWSX library. This allows for evolving subnet requirements without the need to recreate the VPCs.

Starting as a proof of concept, I explored the idea of allowing any Pulumi program to be able to be consumed by other Pulumi programs like a component. This was ultimately not merged, but led to renewed investment in the usability of Pulumi components.

Maintained the CI system for over 100 provider repositories for pull-request and release flows.

• Simplify job matrix for stable job naming and easier tool upgrades.
• Simplify sentinel check for reliable auto-merge behaviour.
• Testing release processes via merge-queues & phony provider.

Wrote a number of small, well defined GitHub actions to help with the publishing of Pulumi providers.

• pulumi/provider-version-action: Generate the version number for any build. With support for PR builds, pre-releases and tagged releases, and major version upgrade flows
• pulumi/verify-provider-release: Ensure published Pulumi SDKs & binaries are usable.
• pulumi/glob-action: Cross-platform glob-based file operations.
• pulumi/git-status-check-action: Check for unexpected file modifications during CI runs.

Coordinating the safe return to offices once COVID-19 restrictions were lifted. Led a team of 4 developers put together this real-time booking app in just 10 days for proactively managing demand for office space by allowing you to book ahead of travelling to the office.

Created the regular expression for a project working with the UK automotive industry. It's received a lot of comments, stars and forks over the years as it continues to be a useful resource for developers.
