Hi, I'm Mark.
An AI-Native Product Design Leader, passionate about my craft, fascinated by the forefront of design technology, and forever striving for impact at scale.
Experienced in team leadership, design direction, systems, process, pitching, and getting things done.
Organizations I've worked with:
Product Design Lead for HP’s support platform, owning quality and systems while steering a mixed-seniority team through complex, ongoing delivery across a high-traffic support experience.
A collection of work designed and led by Mark Preston, in collaboration with agencies, clients, audiences, and other creative teams and individuals.
Working with coding agents on large scale tasks can get messy, and when you're working at speed, reviewing every edit and agent output quickly becomes an impractical task, turning the promise of AI productivity on its head.
Repo OS is my solution to safe hands-free agentic coding, Full case study coming soon.
A Chrome extension and local MCP server for designers who build with AI coding agents. I point at an element on my running site, adjust it by eye, and my agent receives a precise change request: the file and line it lives in, the before and after values, and the design token each value resolves to.
Tinkering since childhood. I love exploring ideas and getting my hands dirty, testing concepts, learning new skills and building my way to working concepts.
