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 usually have a few side projects on the go. Right now in my spare time I'm working on Year of Colour which is a data visualisation tool that shows you the popularity of the colours you’ve used on Instagram throughout the year. It has had over three quarters of a million people use it so far.

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

And on top of that I've helped my wife, Emily Quinton to bootstrap Makelight and her community to lead a balanced, creative life.

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.
