Software Development Engineer Intern

Sep 2026 — Present

Built a Java service automating Elastic Load Balancing (ELB) instance-type configuration rollouts with AWS Step Functions, updating one Availability Zone at a time and targeting approximately 90% less operator time
Implemented SHA-256-validated S3 writes and automatic reverse-order rollback with conditional writes to preserve concurrent changes; verified full restoration through staging fault injection across every rollback path
Built an hourly reconciler comparing EC2 offerings, configuration checksums, and mappings to classify six drift states per instance type across Availability Zones and regions, replacing manual audits with one API query
Built an in-memory AWS Step Functions test harness that runs real rollout code in milliseconds, models retries and error routing, and replays every step to verify idempotency
