Documentation projects

Each project targets a distinct documentation type, audience, and delivery format. The table below maps what was produced. Every linked site includes full dark and light mode support.

Phase 1

CaseForge API Reference

Complete REST API reference for an enterprise AML and SAR-filing platform. Covers authentication, case management, entity screening, SAR submission, and webhooks. Written to Stripe-quality bar: every endpoint has request/response examples, error codes, and field-level descriptions.

What distinguishes this work

MSTP compliance throughout

Every page in this portfolio follows the Microsoft Writing Style Guide: active voice, second person ("you"), sentence-case headings, present tense, no minimizers, task-oriented structure. These are not aesthetic preferences; they are precision tools that reduce reading friction and support translation and localization.

Audience-specific information architecture

Each project starts with an audience definition and works backward to content structure. A developer integrating an SDK needs different navigation landmarks than an IT admin deploying a platform. The IA decisions are documented explicitly in the Information Architecture page.

Portability over convenience

Every project is delivered as static HTML with shared CSS and JS, with no static site generator dependency, no build step required to view or edit. This makes the documentation portable, offline-capable, and embeddable in any environment. The tradeoff is deliberate: simplicity and longevity over toolchain convenience.

Documenting failure states

The most valuable pages in any API or SDK reference are the error handling and troubleshooting sections. This portfolio documents failure modes with the same depth as success paths: exception hierarchies, retry semantics, idempotency key strategy, and per-status-code guidance rather than generic HTTP tables.

Recruiter note

Each project in this portfolio was built to demonstrate a specific documentation skill. The Writing Philosophy page explains the practitioner decisions behind the work: what makes good developer documentation, and how to measure it.

AI & diagnostic tools

Interactive tools built to diagnose, measure, and improve documentation systems, not just describe them.

Tool

Content Pipeline Health Checker

A 4-step diagnostic wizard that identifies where a documentation pipeline breaks when content crosses from source format to delivery surface. Applies Despopoulos's source-to-delivery model and Iantosca's two-gate quality framework. Produces a prioritized fix list and shareable report.
