Developed and integrated the Key Management Secrets Engine for the opentofu/terraform-provider-vault repository, enabling enterprise-grade cross-cloud key management across AWS, Azure, and GCP. Focused on backend development using Go, the work included building KMSE resources to support key creation, distribution, and replication, while enhancing both test coverage and documentation to improve reliability and maintainability. Collaborated on multiple pull requests to implement these features, addressing issues across KMSE paths and tests. Leveraged skills in API development, Terraform, and Vault to streamline Vault-based secrets management, reducing deployment time for customers adopting Terraform-driven key management workflows in multi-cloud environments.
