Hi, I'm Stef Lewandowski:
technologist, designer, venture builder based in London, UK.

I’m currently venture-building at ING bank’s London lab where I’m exploring a new business idea around gathering and processing data about sustainability in order to help us hit the Paris agreement targets for climate change.

I help my wife, Emily Quinton to bootstrap Makelight and support our community to lead a balanced, creative life.

I’m also building a few interesting side projects. Year of Colour is a data visualisation tool that shows you the colours you’ve used on Instagram and has had hundreds of thousands of folks use it so far.

Audrey (my work is the app, not the landing page) is a realtime audio reading experience for two participants who read a book to each other over a series of sittings. It’s aimed at tackling loneliness in older people, connecting distant relatives, helping people learn with each other, and has lots of other uses.

Attending helps you create a simple page about an event that you are running, without all of the complexity of other event organising platforms.

I work on a variety of projects, and I write about what I learn from the process. I speak at events, make up stories, tweet a fair bit, volunteer as chair of school governors , create mixes, draw monsters, mentor startups, teach and inspire a community of people, to create something every day,

My current go-to tech stack is Next.js, React, Apollo, GraphQL, Node, Serverless cloud functions, Postgres and Zeit Now, with possibly a little bit of Ruby here and there.
