01

The problem

Enterprises accumulate documents faster than people can find the relevant fragment. Reports, policies and historical decisions sit across systems, and answering a concrete question often means manually reading for hours.

A naive chatbot over documents is not enough: access control, document timeframes and organisational authorisation all determine who should see what — and wrong disclosure is worse than no answer.

02

Context

Professional engagement on a confidential enterprise document management and reporting system. Specific client, UI, data and architectural details are not disclosed.

This page intentionally stays at system-concept level: it explains the shape of the problem and the approach without exposing confidential implementation.

03

My role

  • Contributed to retrieval-augmented generation flows over enterprise document corpora with authorization-aware access.
  • Worked on timeframe-aware retrieval so answers respect document validity periods and historical context.
  • Collaborated on decision-support reporting surfaces that turn retrieved evidence into structured output for humans.

04

The solution

A retrieval layer that selects documents the requesting user is authorised to see, filtered by timeframe and access policy before generation ever runs.

RAG over curated corpora so answers cite source material instead of improvising, with structured report outputs for decision-support workflows.

Human-in-the-loop review paths: the system proposes, people decide — appropriate for enterprise document contexts where errors have consequences.

Abstract model of the system. Authorization and timeframe filters run before retrieval; generation stays grounded in permitted sources.

07

Implementation

Authorisation is enforced in the retrieval path, not as a prompt instruction — the model only ever sees documents the user is allowed to access.

Document metadata (effective dates, supersession, classification) is first-class, so timeframe questions return historically correct material rather than only latest revisions.

Generation is constrained to retrieved context with citations, and outputs are structured for decision-support review rather than free-form chat.

Concrete technologies, vendors, volumes and interfaces remain confidential and are deliberately omitted from this case study.

08 / Hard parts

The hard engineering.

Security before generation

RAG systems leak if authorisation is checked after retrieval. The design enforces policy inside the retrieval boundary so forbidden content never enters the model context.

Timeframe-correct answers

Enterprise questions are often 'what was true then?' — not 'what is true now?'. Making document time validity a retrieval dimension, not a post-filter, was essential.

Useful under confidentiality

Explaining a system you cannot fully show forces precision: abstract diagrams, honest context labels and clear role statements instead of screenshots that cannot exist publicly.

Results

A confidential enterprise system in active professional use, covering document intelligence, authorised retrieval and decision-support reporting. Specific outcomes, volumes and client identifiers are not disclosed. This case study documents the problem shape and engineering approach only.
