content strategist | UX writer | content writer

United States

Hey there--I’m Jennifer Perez-Harris. I tell stories with systems and systems with stories. Translation? I make complicated products feel simple, usable, and human.

I’ve written for Fortune 100 tech giants, health startups with everything on the line, and now I’m building AI-driven content frameworks that truly scale. My through-line: clarity, every single time.

Here’s how I work:

Start with people. Not personas on a slide, but actual humans struggling (or succeeding!) with a flow.

Design with systems. Patterns, frameworks, and guidelines that keep teams aligned long after I’ve logged off.

Scale with clarity. Content that feels obvious--in the best way.

I help people understand technology, and technology understand people.

T:slim X2 with Control IQ Insulin Pump - Video and Social Testimonials

For this project with Tandem Diabetes Care, I led the creation of an award-winning video built entirely from our customers' own words. I drove the initiative from start to finish, which involved curating the most impactful social media posts, navigating the complex legal permissions process, and providing clear creative direction to our art department. The result was a highly engaging video that celebrated our user community and became one of the company's most-shared assets, significantly...

Data to Dialogue: Creating a One-Page Infographic From Pages of Survey Data

Faced with 15 pages of dense survey data from an elite technical audience, my challenge was to distill it into a compelling, sophisticated narrative that would capture their attention. I created a visually engaging infographic that highlighted the most powerful statistics, and to add another layer of relevance, I incorporated references to key integrations like Splunk. By repurposing this content for social media and email campaigns, we not only created a valuable asset but also achieved a...

Pure Content Writing: Hotel Yasmin Review, Prague

This is a review I wrote for the Prague Post about the Hotel Yasmin, a place with a wild, ultra-modern design that felt like it was from another planet. I focused on how the hotel confidently broke traditional design rules, mixing high-end art with playful, sci-fi themes. I wanted to capture its unique energy, concluding that while other hotels might be a classic beauty, the Yasmin was a 'thundering, six-foot supermodel'—flashy, confident, and impeccably styled."

Content design + content writing: Reshaping a case study into a popular blog post

I wrote this in case study format, but due to brand department demands and a long publishing timeline, it was no longer feasible to keep it that way. I recrafted the case study into a blog post using an “interview” format. With this adjustment, we were able to have the blog post up and ready within one week, using an unpaid social media campaign as support. It received 100,000s of views.

UX Strategy and Writing: HP Portable Lab Style Guide

The project was to create a foundational UX Writing Style Guide for HP's portable labs, serving as the essential source of truth for a large team of coders, writers, and technical staff. The primary goal was to establish clear, consistent, and unambiguous communication standards, prioritizing function over stylistic flair to ensure usability in a technical environment. This was achieved by defining core principles, such as mandating active voice for directness, setting strict rules for...

TimelyCare Telehealth App: A Study in UX Content Strategy and Writing

To engage TimelyCare's 2 million students, I designed a content strategy that let users choose their topics and used data to send timely notifications, boosting engagement 5x. I also led the creation of the company's AI chatbot and its definitive voice and tone guide to ensure a consistent, empathetic user experience.

Cisco Content Maxxing: Splicing a Video Into High Performing .Gifs

When Cisco created a polished 1.5-minute video to launch its new AI firewall features, I saw an opportunity to maximize its impact. The video was great, but too long and broad for fast-paced channels like email and social media. I took the initiative to deconstruct the original asset, editing it into three shorter, feature-specific videos and creating three punchy animated GIFs designed to capture attention. This strategic pivot was a huge success, driving a 43% increase in email...

Building trust through testimony: The t:slim X2 with Control IQ technology

To overcome patient fear surrounding its revolutionary t:slim X2 insulin pump, Tandem Diabetes Care initiated a crowdsourced testimonial campaign to showcase the device's real-world safety and benefits. The strategy was to build a library of authentic user stories that would resonate more powerfully than clinical data alone. Despite significant legal and compliance hurdles in production, the campaign succeeded in creating a compelling collection of patient narratives. This library became a...

UX Case Study: How a Visual Cue Improved Navigation by 90%

To solve a key point of user friction where our push notifications led to a generic home page, my team implemented a two-part solution to create a more intuitive user journey. We first replaced the standard logo in each notification with a small, relevant 'visual cue'—a screenshot of the destination—to give users a preview of where they were headed. We then updated the app's home page to dynamically feature the specific content advertised in the notification they tapped. This direct approach...

Pure Copywriting: Taglines for Amazon Publishing

I was hired by an advertising firm to create a list of taglines promoting Amazon Publishing. To bring my brainstorming document for Amazon Publishing to life, I used Google Gemini's Canva to reshape a static list of taglines into a dynamic 'Brand Voice Explorer.' My goal was to move beyond a simple page of text and create an experience that felt as creative and inspiring as the brand itself. The result is a sleek, interactive tool that presents each potential tagline as a discovery, making...

UX Writing Exploration: Good Food Good Move Website.

For the 'Good Food. Good Move.' campaign with Texas SNAP-Ed, my goal was to translate complex public health guidance into an encouraging, mobile-first website for low-income families. We faced the challenge of transforming a dense, 1,000+ recipe database and requirements from over a dozen stakeholders into a user-friendly resource. To do this, we developed a simple recipe finder and an interactive quiz to make learning about healthy options, like frozen vegetables, engaging and fun. By...

HP case study: Crafting clear and secure UI

As the UX/UI Writer for a confidential HP medical device, I was tasked with writing and editing over 600 UI screens and more than 10 user flows. The core challenge was to create copy that was exceptionally clear, concise, and simple for medical professionals working in high-stress environments with PPE, while also ensuring robust security and accommodating translation needs. By implementing a user-centric writing process, standardizing terminology, and focusing on critical user paths like...

The CARI Chatbot: An Exploration in Persona, Voice, and UX

This case study details the creation of CARI, a healthcare chatbot for TimelyCare, led by Sr. UX Writer Jennifer Perez-Harris. The project's main challenge was designing a friendly and empathetic chatbot personality while navigating strict HIPAA regulations, which meant CARI could not give medical advice. The team developed a distinct persona for CARI—helpful and conversational, but not silly or creepy—and created many unique, on-brand ways to remind users it was "not a...

TimelyCare: A Complete Case Study Proving Value Through Student Feelings

This webpage is an interactive case study for TimelyCare, a telehealth service for college students. Its main purpose is to demonstrate how a "feelings" survey successfully proved the service's value to universities, which ultimately led to a 100% contract renewal rate. The page uses charts and key metrics to show that students use the service primarily for its convenience and that it has a direct positive impact on their academic success and retention. A key feature of the page is the...

UX writing + UI writing: Using economy of language to tighten a UX flow

A simple, side-by-side comparison of a UX / UI flow. Before vs after. The biggest goal here was to shrink the character count in English to make sure we could fit German-language translations (up to 30% more characters than English). These changes were praised by experts at multiple labs.

Content design: Creating a hype video for a product still in development

Cisco Hypershield is an AI-native system that earns your trust while enforcing security everywhere-at AI-scale and speed. To say that Hypershield is industry changing is an understatement. But since the product was still in development, there were no users to interview about a beta. So, rather than talk about an existing product, we talked about how this future product could fit into a cybersecurity professional's future stack. Interviewing two professionals from major companies and an...

Content design + UX writing: Writing and reshaping copy for a mobile first website

A truly local website about fentanyl addiction. This site focuses specifically on the changing drug culture in King County, Washington, which is now inundated with fentanyl and the cause of many overdose deaths. This site had to both change minds and reach the people most vulnerable, and once that happened, drive users to the resources down the block to get tests, get overdose training, and just stay safe.

Content design + UX writing: Building a mobile site for fentanyl safety

This site tackles a new and terrifying trend: fake opioid pills that look nearly identical to the real thing--but just happen to contain fentanyl. The urgency of this site could not be underestimated, with major prescription pill shortages happening across the country, leading to a rise in accidental fentanyl deaths thanks to fake (street) ADHD, anti-anxiety, and other prescription pills. To drive the point home, we created multiple real-sized examples of the amount of fentanyl needed to kill.

UX writing + UI writing: Sample--650+ screen UX flow

Just a sample of a massive set of 650+ UI screens I wrote or fixed over a single week. I was hired at HP one week before a major UX flow review. The problem: No one had reviewed the flow. I sat down and got to work. This flow was lauded for clarity by the test team. Read the next sample for details!

Content writing: One year of writing / editing / growing the XYO technology blog

In my first week at XYO, I began creating an ambitious plan to grow the blog by thousands of readers, and position it as the top resource for blockchain-related content. This was the content. Not only did I add thousands of loyal readers, I became one of Medium's top 10 writers in multiple categories: smart cities, blockchain, and transportation.

UX content writing: Fentanyl safety website for First Lady of Virginia Suzanne S. Youngkin

High-profile fentanyl addiction website spearheaded by Virginia First Lady Suzanne S. Youngkin. The site highlights the fentanyl epidemic in Virginia specifically, and drives users to state resources for fentanyl test strips, addiction counseling, and more. This site was a critical component of the launch of the "One Pill Can Kill" Virginia website, and a broader national campaign. The site asked users to sign a pledge to help stop fentanyl overdose in Virginia. By signing this pledge, users...

Content design + content writing: Creating a mothership-style website for AI firewall

Cisco struggled to sell an AI-powered firewall upgrade due to customer concerns about risk, low brand loyalty and a learning curve. So, I created a comprehensive website with FAQs, tech support, a free trial, more. This delivered a 300% increase in page views, and a 40% increase in free trials. It also shifted marketing from technical to conversational for a broader audience.

Content writing: Ghostwriting a blog post for a popular Cisco thought leader

Ghostwritten blog! In security, users aim for simplicity. Too many tools, too many vendors, too many logins? It's just too much. Yet at the same time, whenever something becomes simpler, the environment becomes less secure. In this blog post, I make the case for simplicity, and the Cisco tools used to make this happen.

Content writing: Writing and designing copy for Cisco's AI Firewall launch page

Another major page from Cisco, this one covering a huge product launch: AI assisted next-generation firewall. This new story had to deliver a real shift in thinking for security pros who were just waking up to AI as a massive time-saver. Part of this was painting a picture of what's possible, starting with a high-level video as the centerpiece for the page. The rest of the page: mixture of sections exploring the trusted legacy features of firewall, and a new slate of capabilities that change...

The first sign of an ambitious, ground-breaking era for Cisco: the AI-assisted firewall. Originally just used as traffic routers, firewalls are now true security devices, spotting threats in encrypted traffic, blocking zero-day exploits, and more. But now, with an AI assistant in the background, all the crap work, the stuff you have to do over and over if you work in security, is no longer an issue. The AI does it. Part of this page was the introduction of this grand, new theme, of AI as a...

Content design + UX writing: Writing and designing a mobile first website and desktop site

Writing about HIV is always a challenge, but especially so right now because many communities aren't aware that there are preventative medications with an almost 100% success rate. Our task was to introduce a sort of holistic prevention lifestyle, focusing on avoiding HIV in the first place, rather than relying on medications to manage HIV after exposure. The silver lining? We've come a long way. Thankfully, HIV is no longer the threat it once was.

UX writing and content writing: Writing a mobile first website to help readers quit smoking

Quitting smoking has never been easier (or harder -- depending on who you ask) -- especially when you're on your own. So, Illinois created their own site to give readers every resource possible to help them kick the habit when they're solo. Would you like to chat with someone? Sure. Want a phone call? We got you. If you're a smoker in Illinois and you want to quit, you have everything at your fingertips to make it happen.

The U.S. trucking industry generated an astonishing $700 billion in 2017, a 3.5% boost over the previous year. And the industry's only going to get bigger and more complex. But to convey just how complex it is, one has to start with the right scenario.

An INSANELY difficult project that ended up being a smashing success. ResMed CPAPs are powerful devices, but on the downside, they require complex troubleshooting techniques. I worked with product and design teams to create the most thorough, accurate guide possible. After many hours with product and technical reps, I worked with a Sr. designer to build a multi-page guide complete with steps for everything from fixing a mask leak to raising air pressure. This guide became a sort of bible for...

Copywriting: Dropship box copy - Resmed Airsense 10

This box copy was written to make patients feel comfortable when they receive their Resmed AirSense 10 CPAP and accessories in the mail. For the first-time CPAP user, even opening the box can seem intimidating. Inside the box are a lot of parts and a lot of things to read, so I wrote the copy to a) calm the user, and b) make them feel optimistic about their choice to use a CPAP device. This copy was also used for other types of CPAP devices.
