Jan 1, 2025January 2025: Delivered the Firewall Target Group IP Target Validation and Support feature for awslabs/landing-zone-accelerator-on-aws. This enables IP-based targets in firewall target groups (IPv4/IPv6) with strict validations to prevent crossing IP versions and to ensure correct target configuration. Implemented updated validation logic and comprehensive unit tests for IP address and firewall target group validation. No major bugs were reported this month; the work reduces misconfiguration risk and enhances deployment reliability. Impact includes enabling precise, scalable firewall configurations in customer environments and accelerating secure network setups. Technologies/skills demonstrated include infrastructure-as-code validation patterns, test-driven development, and commit-level traceability to improve maintainability.
