What I'm looking for

My love tackling complex problems. This means I prefer working on feature-rich products, like internal enterprise software, SaaS or professional tools.

I would also love to continue to work with companies who are either AI first or implementing AI into their products.

So that's it, challenging, impactful work with great people.

I'm a product designer with over 5 years of experience specializing in enterprise AI and developer tools. Currently at Workhuman, I focus on integrating AI features into core product experiences impacting millions of users daily.

My expertise centers on transforming complex technical systems into intuitive interfaces for expert users. I excel at bridging technical complexity with user needs, designing everything from real-time monitoring dashboards to developer workflow tools. My technical background in HTML, CSS, and JavaScript helps me collaborate effectively with engineering teams and understand implementation constraints.

I have strong leadership experience, having built design teams while implementing standard processes and mentoring junior designers. I also built and maintained design systems alongside FE engineers.

My educational background includes an MSc in Design Innovation from Loughborough University London and professional certifications in Product Management and Fintech. I'm particularly drawn to roles combining complex problem-solving with measurable business impact, whether improving developer workflows, enhancing data visualization, or creating AI-powered user experiences.

Outside work, I’m obsessed with rugby, tinkering with tech and reading sci-fi book series. I'm passionate about creating products that make sophisticated technology accessible to the people who depend on it most.
