Developer documentation

Built and maintained API, SDK, and connector doc at Unity, npm, and Google. Comfortable in Docs-as-Code pipelines, GitWiki, Markdown, XML, and working directly with engineers in Agile sprints.

UX writing & content strategy

Collaborated with UX designers at Unity to write dashboard copy, error text, and onboarding flows. Developed surveys to measure doc usability and led inclusive language initiatives company-wide.

Instructional design

Created highly-rated training courseware for Hitachi Rail's automated systems software, including cybersecurity modules. Worked across time zones with SMEs in Italy, Pittsburgh, and the West Coast.

Customer storytelling

At Splunk, wrote technical customer stories that accelerated the sales cycle for major opportunities in banking, airlines, government, and IoT. Also managed sales enablement quick-reference cards.

This portfolio is actively being expanded. Additional embedded work samples coming soon.

Unity Technologies
Cloud Auth & Gaming Services Doc

Lead writer for Unity Authentication, Ad Tech, Programmatic, and Gaming Services — hundreds of customer-facing pages. Drove UX writers into Figma for dashboard copy, and built Data Studio analytics dashboards to inform content priorities.

Convinced product managers to involve writers earlier in Agile sprints
Initiated inclusive language effort presented at company-wide ERG meeting
Built Data Studio dashboards tracking doc analytics across GCP
Mentored new writers on tools, style guide, and peer review processes

“Carolyn’s SDK documentation is extremely clear and user-focused. She really gets the user. And she handles challenging complexity well.”
— Nick Richards, Software Engineer, Unity Technology

I was the original author and information architect for these pages, creating most from scratch during 2018–2022. The structure, voice, and IA you see were established by me. Content may have been updated by others since my tenure.

Splunk
Technical Customer Stories

Discovered, researched, and wrote complex customer stories that made Splunk's features understandable to C-suite buyers. Stories were credited with accelerating the sales cycle for major opportunities across multiple industries.

Industries: banking, airlines, IoT manufacturing, government
Obtained Splunk certification to produce authentic scenario-based screenshots
Created sales enablement quick-reference cards distributed via Salesforce
Promoted stories via Twitter and LinkedIn to extend reach

“These stories help customers expand their minds regarding what Splunk can actually do.”
— Maverick Garner, Sales Engineer, Splunk
“It’s great that we have an awesome tech writer who can make these stories come alive!”
— Young Cho, Sales Lead, Splunk

I researched, wrote, and published every customer story on these pages during 2014–2015. Splunk had an existing customer stories function when I joined — I overhauled it, created contests to incentivize the sales team to submit story leads, and raised the quality and volume of stories significantly.

Information Architecture Redesign

Redesigned the Dev Ops team's knowledge infrastructure, transforming thousands of disparate Confluence pages, Jira tickets, Slack messages, and internal blogs into a navigable, active resource. Validated the new structure through card sorting and 1:1 sessions.

Used Optimal Workshop card sorting to prototype and test IA with real teams
Created short explainer videos for staff and management
Designed runbook, postmortem, and Technical Design Doc templates
Validated usability with newly onboarded team members
IAConfluenceOptimal WorkshopFigma
Case Study

“The new documentation architecture will accelerate productivity across the board.”

The Challenge

ProbablyMonsters included independent game design studios with a best-of-breed but highly specialized IA. Valuable content was scattered across Slack, Atlassian Confluence, and SharePoint — difficult to find and often duplicated.

The Method

Used search analytics, tree testing, card sorting, and stakeholder interviews. Spent time understanding what ProbablyMonsters' goals required — predicting needs users didn't yet verbalize.

The Results
  • Duplications eliminated
  • Obsolete content clearly archived
  • New information surfaced first
  • Content "lost" in Slack organized intelligently in Confluence
  • Templates with keyword fields built to sustain the new structure

“She has a gift for simplifying complex technical concepts . . . and is a fantastic human being who is a blast to work with.”
— Shivaun Robinson, MBA, Program Manager, ProbablyMonsters

I designed this information architecture from the ground up in 2022–2023, starting with thousands of disorganized pages. The structure, templates, and navigation were created by me.

I was the sole instructional designer and writer for this courseware in 2024–2025. In keeping with standard NDA practice, certain technical details and system architecture have been deliberately obscured in the samples shown — this is intentional, not an oversight.

Unity — Analytics
Data Studio Doc Analytics

Built Data Studio dashboards ingesting Google Analytics for doc performance monitoring. Trained engineering teams in a Lunch and Learn session; insights drove localization priorities and content revisions for both the Doc and MarCom teams.

Created sample charts and tutorial documentation for engineers
Doc and MarCom used dashboards to identify revision and localization targets
Monitored GCP Google Cloud Billing Costs via Data Studio reports
