Product Designer | UK Based

  • Donya is a brilliant designer who has quickly become a key contributor to how we discover, define and deliver core platform functionality. She brings a strong mix of curiosity, structured thinking and bias to action. Donya excels in early-stage discovery: she can quickly get to grips with complex problems, facilitate and synthesise stakeholder research and turn it into action plans with high-impact interactive prototypes (powered by AI!). Her work consistently helps product and engineering align on the right solution faster.

    On a personal level, Donya is empathetic, ambitious and highly coachable. She has shown significant growth in her technical abilities and confidence over a short period while at THG. I'd strongly recommend her for any UX role where you need someone who can handle ambiguity, prototype at pace and collaborate deeply with cross-functional teams.

  • I've had the pleasure of working with Donya over the past year, and she's been a huge part of improving both our product and the way our team works together.

    She has a really good eye for clean, modern design, but what I appreciated most was how much thought she put into making things clearer and less confusing for users. Her designs always felt intentional and easy to use, which made a big difference for the product.

    She's also just genuinely easy to work with, always open to feedback, happy to answer questions, and proactive about asking for other people's opinions before making decisions. That collaborative attitude made working with her feel very natural and productive.

    Any team would be lucky to have her as a UX designer, and I'd happily work with her again.

  • Donya has a strong eye for interaction and visual design, working closely with developers and embracing emerging tools like Claude Code and AI-assisted workflows alongside them.

    Alongside her UI and interaction design strengths, she conducts effective user research and testing to help inform product decisions, and has presented several impactful improvements. She has experience working within modern design systems across Figma, Storybook environments, and structured documentation practices like skill.md files in Claude.

    I'd strongly recommend her to any team looking for a forward-thinking designer who balances craft, research, systems thinking, and emerging technology.
