Project index / 05 cases

Five cases.
Every decision visible.

Two independently owned software projects and three fictional design exercises. Open a case to see the problem, my contribution, a working example or design, and the limits of its evidence.

Source identity and section path stay attached to the converted text.

Real CLI output; invented source; static browser replay.

01 / Document AIIndependent software

Document Context

Prepare documents without losing their source.

Local conversion produces structured Markdown and source-linked chunks for downstream AI workflows.

Evidence: Real CLI artifact from a fictional standard

Design decisionKeep source identity and section context attached to each chunk.

Use caseStaff knowledge assistant
Open decisionWhich local policy and approval path apply in a real organization?

Specialists receive questions; a model does not issue an approval.

Concept diagram; simulated prewritten responses; no running agents.

02 / AI operating modelFictional design concept

AI Use Case Studio

Make an AI use case reviewable before build.

A proposed workspace connects intake, dependencies, specialist questions, and future-state design.

Evidence: Fictional concept walkthrough

Design decisionKeep agent proposals separate from human approval.

Fictional working example
Evidence is a check.Approval is a decision.
Human disposition + written reason
Fictional review recordEX-1042
P-01Receipt recorded.Present
P-02Manager approval missing.Gap
P-03Business purpose recorded.Present

The reviewer records the disposition and reason.

Invented records; inspectable rules; human decisions.

03 / Risk operationsFictional design exercise

Evidence Review

Show missing evidence before a reviewer decides.

Deterministic checks expose the reason for each gap while leaving the decision with a person.

Evidence: Three fictional review records

Design decisionRequire a reasoned human disposition even when checks pass.

Ambiguous reference? Keep the exception open.

Fictional rule outputException day
TXN-205amount varianceOpen
TXN-206ambiguous referenceOpen
TXN-207missing feedOpen

Duplicate and mismatched records are not forced into a pair.

Invented records; inspectable rules; human decisions.

04 / ReconciliationFictional design exercise

Ledger Match

Keep ambiguous ledger matches open for review.

Exact reference-and-cent pairing separates clear matches from four types of exception.

Evidence: Two invented batches with rule tests

Design decisionNever force a match when source records are ambiguous.

Advisory queue · no automatic posting

Fictional journal reviewMay 2026
J-401Account 6150 / EAST$4,200
J-402Account 6150 / EAST$4,200

A possible duplicate needs evidence. No posting changes automatically.

Invented records; inspectable rules; human decisions.

05 / Financial closeIndependent prototype

Close Workbench

Bring close exceptions into one reviewer queue.

Journal and invoice signals appear with supporting records and the next human check.

Evidence: Working static prototype with fictional data

Design decisionTreat every flag as advisory, not an accounting conclusion.

About these cases

Document Context and Close Workbench are independently owned; their browser examples are fictional or fixed as labeled. Cleared résumé outcomes do not authorize publication of employer or client code, screenshots, data, or detailed project case studies; those remain under separate review.
