Designing @ Jigsaw

Hi, I’m Lewis Ngugi, a Senior Product Designer based in London.

I turn complex systems into clear, useful products. I’m currently designing the Timelines product at Jigsaw. Before that, I led AI support design at HubSpot, research tools at Lookback and a banking platform for credit unions at Kwara. 10+ years across B2B platforms and consumer products.

Writing

Notes on design, product and the places I’ve worked, from London to Nairobi.

What London Shows Nairobi

A product designer on Granola's Made in the UK series: how UK founder schemes compare with Nairobi's Silicon Savannah, and what to borrow.

Same pattern, different city

Most product data lives on a timeline but gets scattered across tabs. Metro maps and layered calendars show the insight lives in the layers.

Interviews & Podcasts

I talk about design and community and host brilliant people on my podcast to share their insights.

Travel

I learn design by moving through systems: buses, bicycle rickshaw, canoes, markets, museums, and walking tours. From Halong Bay to the Sahara, travel teaches me how people adapt, navigate and make meaning. That always reminds me that good design is local, human, and shaped by context.
