Hello, my name is Raine Luntta 👋
I have a passion for polished human experiences - for customers, users and developers. I've been designing, engineering and building impactful products, services, businesses and teams for over 15 years.
Currently I'm leading design at Fintraffic. I also contribute, develop and maintain open source projects, such as Aihio - a design system for humans and agents.
Principles
How I try to live my life and lead others.
- People over process
- Experts leading experts
- Small teams achieve more
- Strong opinions, weakly held
- Wicked problems, patient work
- Err on the side of do
- Fall in love with the problem, not the solution
- Eat your own dog food
- Start with the experience and work backwards to how it's done
- It's more fun to be competent
- Darkness cannot drive out darkness; only light can
- Passion is how you achieve ambitious goals
