Software Development Engineer
Amazon Web Services, Inc.
Seattle, WA
01.2023 - 07.2024
- Architected and maintained a high-availability IAM Control Plane database solution, ensuring scalability, durability, and resilience.
- Engineered a backup optimization framework, reducing S3 storage usage by 80% via automated backup trimming and lifecycle management.
- Designed a secure key rotation system for IAM cryptographic keys, leveraging AWS KMS, Lambda, and EventBridge, addressing audit compliance.
- Implemented health and performance monitoring for IAM storage layers, enhancing system observability and proactive fault detection.
- Developed tools for database schema changes, ensuring seamless updates and rollback mechanisms for key management and security enhancements.
- Optimized and executed automated test cases for APIs and system components, ensuring reliability and compliance with best practices.
- Used Sysbench to benchmark and optimize database performance, ensuring efficient query execution and system throughput.
- AMDB Backup Optimization & S3 Space Reduction:
- Spearheaded the optimization of AMDB backup storage in AWS S3, achieving a 80% reduction in space usage. Designed and implemented the AMDB Backups Trimmer and S3 Lifecycle Manager components to automate backup trimming, which successfully retained only the first snapshot per day for each backup host. The solution ensures backup efficiency while preserving data redundancy.
- IAM AMDB Key Storage and Rotation:
- Led the design and implementation of a secure, automated key rotation system for IAM AMDB’s cryptographic keys, including Master Keys (MK) and System Keys (SK). Developed the solution to rotate keys every 90 days, integrating AWS KMS for key encryption, Lambda functions for automation, and Event Bridge for event-driven triggers. This approach improved security posture and addressed AWS audit findings.
- IAM AMDB Master and System Keys Rotation:
- Designed and developed an automated system for rotating IAM AMDB Master and System Keys. Ensured the periodic creation of new keys, secure storage in S3, and re-encryption of existing system keys using the new MK. Integrated AWS Step Functions to manage workflows, S3 lifecycle policies for backup key management, and re-encryption processes for database records.
- AMDB Schema Changes for Key Rotation:
- Implemented necessary schema changes to support the rotation of IAM AMDB Master and System Keys. This included adding new columns for key statuses and fingerprints, updating system tables to track key usage, and ensuring database integrity during the rotation process. Also developed manual and automated testing workflows to ensure seamless schema updates and rollback capabilities.
