PROFILE

Douglas Willcocks

Worked on backend stability and reliability across two major repositories, focusing on complex dependency management and event-driven architecture. In pulumi/pulumi, addressed deployment determinism by fixing an unawaited Promise in the resource dependency graph, ensuring correct resource creation order and reducing CI flakiness. This involved TypeScript and Node.js, with regression tests added to lock in the behavior. Later, in getlago/lago-api, improved observability by refactoring the Event Processor’s logger subscription, resolving compatibility issues with log events and enhancing monitoring. Leveraged Ruby on Rails and event-driven patterns, emphasizing code quality, traceability, and robust backend development practices throughout both projects.

February 2025 (pulumi/pulumi): Stabilized the resource dependency graph for transitively referenced resources. Fixed an incomplete dependency graph caused by an unawaited Promise in addTransitivelyReferencedChildResourcesOfComponentResources, ensuring resources are created in the correct order. Added regression tests to lock in the behavior. This work increases deployment determinism, reduces risk of misordered resource creation in complex graphs, and improves overall reliability for users modeling transitively referenced resources.
