Open-source module
Terraform AWS CloudTrail Module
Co-built an open-source Terraform module that made customer AWS onboarding repeatable for a managed security platform.
The problem
Onboarding customers into managed security required the same CloudTrail wiring in many different AWS accounts, often by operators who were not Terraform experts.
What I worked on
Co-designed, implemented, tested, and documented the public module with the platform team.
Key decisions
Used composable modules, clear variable contracts, and explicit dependencies so teams could adapt the module without reading every resource definition.
How I handled failure
Treated documentation and predictable interfaces as part of the release because open-source consumers depend on stable module behavior.
Result
Multiple customer integrations adopted the module, cutting manual onboarding steps for both Expel and its customers.
