# AJA Video Systems

> 70+ product manuals and REST API documentation for professional video hardware

## The Project

AJA Video Systems manufactures professional video hardware for broadcast, post-production, and ProAV markets. From 2016 to 2022, I was one of two technical writers responsible for all product documentation.

## What I Delivered

<CardGroup cols={2}>
  <Card title="Bridge Live" icon="video">
    120-page flagship guide for AJA's most complex multi-path live streaming system. Covered
    signal routing, encoding profiles, redundancy failover, and REST API control.
  </Card>

  <Card title="Bridge NDI 3G" icon="network-wired">
    120-page companion guide for NDI protocol streaming. Documented network discovery,
    bandwidth management, and multi-channel configuration.
  </Card>

  <Card title="70+ Product Manuals" icon="book-open">
    Full catalog coverage: encoders, converters, routers, frame synchronizers, monitors.
    30–120 pages each, maintained across firmware releases.
  </Card>

  <Card title="REST API Documentation" icon="code">
    Initiated and built the company's first REST API docs — 8-chapter developer guide covering 7 products
    across the Ki Pro and HELO lines. Partnered directly with engineers through iterative review cycles.
  </Card>

## How I Worked

* Configured multi-product setups daily (encoders, routers, converters, monitors) — hands-on validation, not speculation
* Tracked signal flows across 4+ devices to verify documented behavior
* Served as informal QA, catching errors before release
* Reduced support ticket volume through comprehensive self-service documentation

## Skills Demonstrated

<AccordionGroup>
  <Accordion title="Single-author at scale">
    Developed templates, style guides, and revision workflows that held up across 70+ products.
  </Accordion>

  <Accordion title="Hardware validation">
    Physically configured the products I documented — not relying on engineer descriptions alone.
    Signal flows, connection diagrams, and procedures were tested hands-on.
  </Accordion>

  <Accordion title="Template design from scratch">
    Built documentation structures for product categories that didn't have precedents
    (multi-path streaming systems, REST API control interfaces).
  </Accordion>
