01 / Overview
The problem and my contribution.
Document analysis products handle sensitive files, so a convincing demo must do more than display a score. It needs real accounts, private ownership, validated uploads, extractable text, explainable findings, and safe deletion.
My roleProduct design and full-stack development
OwnershipIndividual project
I designed the workflow and implemented registration, verification, sessions, document ownership, extraction fallbacks, local analysis, document-grounded chat, reports, admin review, tests, and deployment packaging.
02 / Architecture
How the product is put together.
Authorization
Session, role, ownership
Analysis
Extraction and risk engine
Storage
Private files + relational records
Technology choices
Laravel + Blade
Secure server workflows and a polished multi-page bilingual interface.
MySQL + Eloquent
Explicit ownership between users, documents, analyses, and chats.
PDF / Word extractors
Layered parsers keep extraction useful across environments.
Local analysis + optional AI
Core risk analysis works without a paid key; enrichment is optional.
03 / Engineering
Challenges and decisions.
Every read, report, question, download, and delete checks document ownership on the server; admins are the only explicit exception.
PDF and Word processing use primary tools and fallbacks instead of assuming one parser works everywhere.
The local engine returns score, clauses, dates, recommendations, and a summary instead of an unexplained label.
