01
Context
The system and the operational problem.
Large file uploads and private storage require more than a polished interface. The product needs predictable chunk handling, authorization, recoverable processing, integrity checks, and clear file states across folders, favorites, trash, and future sharing.
02
Responsibility
What I owned and what I contributed.
Independent product and engineering work across application architecture, backend workflows, frontend delivery, and development infrastructure. Features are labeled by current implementation status rather than presented as a finished commercial service.
03
Constraints
The engineering challenge.
- 01
Breaking large uploads into recoverable chunks
- 02
Keeping file metadata and assembled objects consistent
- 03
Balancing encryption and integrity checks with usable workflows
04
Approach
How the problem was framed.
- 01
Separate upload intake from background file assembly so long-running work is recoverable.
- 02
Track upload state and checksums explicitly rather than relying on the browser session.
- 03
Model familiar workspace actions—folders, favorites, and trash—before expanding into sharing.
05
Implementation
The layers that made the workflow work.
Frontend
React and TypeScript interfaces for uploads, navigation, file states, folders, favorites, and trash.
Data & processing
MySQL metadata, Redis queues, checksums, AES encryption at rest, and chunked file processing.
Infrastructure
Docker-based local services with a public product preview for inspectable UI evidence.
06
Operational value
Concrete outcomes, without invented metrics.
- Establishes a reusable upload pipeline instead of coupling large-file work to one request.
- Makes file state and recovery behavior explicit across the workspace.
- Creates a stable foundation for planned sharing and collaboration workflows.
Engineering reflection
The core product challenge is state integrity, not the upload button. Clear boundaries between intake, processing, storage, and metadata make later features safer to add.
