    "displayName": "File Storage / Object Gateway (Go, Boto3, PostgreSQL, Redis, Docker)",
    "description": "A multi-tenant object storage gateway that provides a unified API over\nheterogeneous storage backends with access control, quota management,\nand lifecycle policies. Go powers the gateway with high-concurrency\nrequest handling, streaming multipart uploads, and content-addressable\ndeduplication. Boto3 interfaces with cloud object storage as the\nprimary backend, while the gateway adds metadata enrichment, virus\nscanning hooks, and access token validation. PostgreSQL stores object\nmetadata, bucket policies, quota usage, and access audit logs.\nRedis caches authentication tokens, presigned URL validations, and\nhot object metadata for frequently accessed files. Docker enables\ndeployment as a stateless gateway tier behind a load balancer. The\ntradeoff is maintaining consistency between the metadata database\nand the underlying object store, and managing multipart upload\nlifecycle cleanup.\n",
