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