Delivered two substantial EC2 networking capabilities in opentofu/terraform-provider-aws (February 2026): 1) CRUD-enabled EC2 Secondary Networks and Subnets with error handling and tests; 2) Secondary Network Interfaces on EC2 Instances with new schema, instance creation/flattening integration, tests, and docs. Fixed semantic errors, enhanced semantic checks, linting, and semgrep issues. Improvements reduce configuration drift and enable reliable, declarative provisioning of complex EC2 networking. Strengthened Go-based provider skills: Terraform Plugin SDK, resource schema, tests, and documentation.

December 2025: Delivered the durable_config feature for AWS Lambda in the Terraform AWS provider, enabling durable configuration for long-running Lambda processes with configurable timeouts and state retention. Included changelog entry, naming consistency refactor for retention attributes, and runtime upgrade to Node.js 22.x to ensure compatibility and test stability. Updated tests and linting to improve CI reliability and prepared release-ready documentation and changelog entries.

Delivered reliability and test improvements for the vfsfitvnm/terraform-provider-aws Control Tower baseline workflows in September 2025. Key changes include more robust import state verification and parameter construction using the account ID for the baseline, and introducing an OU provisioning dependency to prevent race conditions. The Control Tower baseline test suite was hardened with serial test execution and corrected tag tests, reducing flakiness. These updates improve provisioning predictability, reduce import/test failures, and strengthen the provider’s Control Tower capabilities, enabling safer, faster infrastructure deployments across multiple accounts.
