I’m a cloud infrastructure engineer focused on designing secure, scalable AWS/GCP systems with real production ownership. In my internship, I was the sole engineer responsible for end-to-end cloud infrastructure—provisioning, IAM least-privilege hardening, and VPC network segmentation—on a live multi-user file storage platform.

I reduced unauthorized access risk to near zero and maintained zero security incidents by enforcing strict data isolation and time-limited access patterns. I also eliminated backend exposure for file transfers by ensuring downloads were served via expiring signed URLs with no direct bucket access, minimizing attack surface across each user’s storage.

I shipped a complete AWS-to-GCP migration with zero data loss by diagnosing DynamoDB vs. Firestore indexing incompatibility and restoring full feature parity through manual composite index configuration and re-provisioning. I further improved operational reliability and cost control with observability baselines, budget threshold alerts, containerised deployment, and reproducible one-command infrastructure provisioning.
