Support multiple PDF uploads to build combined master resume

[dsmithnautel]

Summary

Allow users to upload multiple resume PDFs and merge them into a single comprehensive master experience database.

Use Case

Users often have:

• Different resume versions for different roles
• Old resumes with experiences not in current version
• Multiple documents (CV, resume, project list)

Features

Upload Multiple Files

• Accept multiple PDFs in single upload
• Show upload queue with progress
• Process files sequentially or in parallel

Merging Logic

• Detect duplicate experiences across files
• Handle conflicts when same experience differs (see conflict resolution)
• Merge unique experiences into master
• Preserve source file reference for each atomic unit

Conflict Resolution

Options to implement:

• Manual review: show both versions, let user pick
• Keep both as variants: user chooses when tailoring
• Smart merge: LLM combines best parts (with user approval)
• Timestamp priority: newest version wins

UI

• Multi-file upload component
• Merge preview showing what will be added/conflicts
• Progress indicator for multi-file processing

Priority

Medium - enhances master resume building workflow

Conflict Resolution Decision: Smart Merge

Going with Option C: Smart Merge as the primary approach.

Implementation

• When duplicate experience detected, LLM combines best parts of both versions
• Extract facts from both versions
• Generate merged description that captures all relevant details
• Show user: original A, original B, and proposed merge
• User approves or edits the merged result
• Store merge history for audit trail

Fallback

• User can always reject merge and pick one version manually
• Option to keep both as separate variants if merge doesn't make sense
