Document Processing App Development

I'm looking for a developer to create a small app, either web-based or Firebase-based, with the following features:

File Upload:
- Upload two files:
- One editable Word document (.docx)
- One reference file (scanned document)

OCR Text Extraction:
- Use Tesseract to extract key text values from the reference scanned document.

Document Editing:
- Replace specific fields in the uploaded Word document while fully preserving its formatting.

Output:
- Provide the final modified document in .docx format.

Ideal Skills and Experience:
- Experience with file uploads in web or Firebase applications
- Proficiency in Tesseract OCR integration
- Strong knowledge of handling and manipulating .docx files
- Ability to ensure formatting preservation during document edits

Looking for clean, efficient, and reliable code. Please share relevant experience in your bid.
