Operational Challenges

Critical bottlenecks prior to system deployment

  • Resilient chunked uploading and downloading for 10GB+ video archives.
  • Ultra-lightweight native desktop sync avoiding Electron's heavy memory bloat.
  • Multi-cloud storage abstraction (S3, Wasabi, SFTP, WebDAV).
  • Smart bi-directional file conflict resolution between web and local folders.

Architectural Decisions & Trade-offs

Engineered design choices, technical rationale, and evaluated trade-offs

01

Built Native Desktop Sync using .NET 8 MAUI over Electron

Architectural Rationale:

Achieved ultra-low memory footprint (<40MB RAM) and direct kernel-level file I/O integration.

Calculated Trade-off:Initial scope dedicated to Windows, deferring cross-platform macOS/Linux desktop releases.
02

Engineered a Universal Storage Abstraction Layer

Architectural Rationale:

Allowed clients to plug in cheap S3-compatible providers (Wasabi, MinIO, SFTP), slashing storage costs by 75%.

Calculated Trade-off:Added complexity maintaining unified abstraction drivers across diverse protocols.

Architectural Lessons Learned
"If rebuilt, I would implement Block-level Delta Sync (rsync algorithm) to synchronize only modified byte chunks inside huge files rather than re-uploading the entire file on minor edits."
