Just let me write
For more than a decade, I’ve helped product and design teams in gaming, tech, and entertainment turn complex ideas into clear, actionable experiences. My writing helps teams articulate their vision, align stakeholders, and translate strategy into interfaces that ship and scale. From early concept and research to design systems and final UI, I work across the entire product lifecycle to help companies communicate better products, reach their goals, and grow their business. I specialize in:
UX Writing
Product copy and language systems for large-scale platforms with complex stakeholder environments.
I turn complex product decisions into clear, consistent experiences that help teams ship with confidence. My work brings structure to product voice, interface language, and system-level communication so users understand what a product does and how it works.
As a Lead UX Writer, I managed product copy across an organization with more than 100 designers and cross-functional stakeholders, partnering with research, marketing, monetization, legal, partnerships, platform engineering, and customer experience. Through structured language systems and close collaboration, I helped teams articulate product intent, align decision-makers, and deliver cohesive user experiences at scale.
UX/UI & Product Design
Interaction design and product development from concept through shipped experience.
I design user flows, interfaces, and product experiences that translate strategy into intuitive, usable systems. My work balances user needs with business goals—turning complex ideas into products that teams can confidently ship and scale.
Beyond collaborative product work, I also design and ship independent tools when existing solutions fall short, taking products from concept and interaction design through development and launch.
System Design
Designing product ecosystems that connect users, platform capabilities, and monetization models.
I design product systems that connect features, user roles, and platform capabilities into cohesive experiences. My work focuses on structuring how different users move through a product and how monetization, platform APIs, and real-time interactions integrate into a unified system.
This includes designing in-app experiences, extension interfaces, onboarding and settings flows, and the design systems that support them. By defining patterns, components, and interaction models early, I help teams build products that remain consistent, scalable, and easier to evolve as the platform grows.
Design Systems
Foundational UI frameworks and language standards used across multi-team product organizations.
I build design systems that enable large product teams to move faster while maintaining consistency. My work focuses on defining reusable components, interaction patterns, and language standards that reduce design friction and support scalable product development.
As part of an early design systems initiative within a large platform organization, I helped establish foundational UI components, documentation, and copy standards used across dozens of product teams.
Toolbox
Cross-disciplinary tools used across product design, interactive media, and real-time development.
My background in game development and product design has given me a broad technical toolkit across design, prototyping, and production environments. I’m comfortable adapting to new tools and workflows quickly, and I focus less on specific software and more on the systems and collaboration practices that help teams ship better products.
Selected work
A few projects I can publicly share. Most of my work lives inside products, behind teams, and under NDA, so portfolios are rarely a complete picture.

Projects
Solo projects I create end-to-end. Although I code with AI assistance, the content and design work is 100% human.
BitBuff
Gamified fitness for Twitch streamers
- Product & system design: end-to-end ownership from concept to release on the Twitch Extension store.
- UX writing & UX/UI design: flows, copy, and UI for viewer and streamer experiences.
- Monetization & chat integration: Bits, extension APIs, and chat so viewers can queue and support training on stream.
BitBuff is a revolutionary Twitch extension that turns “I should do something” into doing what your viewers want to see. Viewers queue "training" activities for free or with paid Bits, then you do them on stream to gain experience and stats toward specialized jobs. You tap into endless entertainment possibilities, viewers get to be part of the show, and everyone has a reason to keep coming back. Over 1,000 extension activations in the first week after release. Available for free on the Twitch Extension store.
GoetiaAI
A chatterbox, not a chatbot
- Product strategy & onboarding: from idea to live product; over 4,000 preregistered for beta.
- Design system: components, wireframes, dark/light themes, and copy standards for the application.
- UX writing & design: personality, voice, in-app copy, and flows so streamers and viewers can talk to the AI in real time.
- Implementation: Python, GPT, and Twitch integration to ship a context-aware, human-like cohost.
GoetiaAI gives streamers an AI cohost that actually shows up. Fully customize a personality, voice, and presence that you and your viewers can talk to in real time. You get a companion that reacts to chat, remembers context, and works with your favorite TTS and even VTuber setups so your channel feels more alive. Over 4,000 people preregistered for the beta. I designed the product experience, built the application's design system (dark/light themes, components, copy), and drove it from idea to live product.
In development: Alpha Purredator
A first-purrson battle royale
- UE5 foundation: entirely built in Unreal Engine 5.
- First-purrson action: cat-forward camera and movement tuned for fast engagements.
- Cat-on-cat crime: use power-ups and strategic maneuvers to outwit your opponents.
Twitch Design System (Core UI)
Shared design language and copy standards for Twitch products.
- UX writing & style guide: voice, tone, and in-product copy standards across the design system; copywriting guidelines and documentation so product and design stay consistent.
- Taxonomy & information architecture: naming, structure, and discoverability so features are easy to find and use; shared language between design and engineering.
- Documentation & components: copy for primitives and patterns; alignment with Core UI engineering and feature teams.
Core UI is Twitch’s design system: a shared set of design tokens, React components, and a Figma library that keep product experiences consistent and accessible. I focused on UX writing, the style guide, and taxonomy—defining voice and tone for the system, writing and maintaining copy standards and documentation, and shaping naming and structure so designers, engineers, and users could find what they need. The system supports web, mobile, and TV; documentation lives as the single source of truth so design and code stay aligned.
