Work Experience

Software Development Engineer (SDE) Intern

Amazon Web Services (AWS)

May 2026 - Aug 2026
Greater Seattle Area, WA
  • Team: Amazon RDS for Db2 (Managed IBM Db2 Database Services on AWS RDS Infrastructure)
  • Engineered an in-place state mutation engine, transforming a days-long O(n) backup/restore process into a ~15-second O(1) in-place mutation operation by directly mutating filesystem, catalog, and metadata states.
  • Designed crash recovery mechanisms, idempotent execution, and distributed locking (check-locks/concurrency barriers) to guarantee system resilience and consistency during unexpected mid-operation failures.
  • Developed a comprehensive threat model to identify potential attack vectors introduced by low-level filesystem mutations and authored corresponding security mitigations.
