Designing @ Jigsaw

Hi, I’m Lewis Ngugi, a senior product designer based in London.

Previously worked with HubSpot, Lookback and other tech companies to turn complex systems into clear, useful products and services. Over the past decade, I’ve worked across complex B2B platforms and consumer products. From early-stage startups to large enterprises, I ship outcomes through craft, systems thinking and strategy. I focus on measurable impact and experiences that scale.

Writing

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

All writing
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.
