I'm Daniel, a freelance full-stack developer in Helsinki. I turn ideas into polished web and mobile products, shipped end to end and built to last.

I'm Daniel Dunderfelt, a freelance full-stack developer based in Helsinki. I've been building software for the web and mobile for over a decade, and for the last several years I've done it independently, taking products from an empty repo all the way to real users in production.
I'm most at home with TypeScript, React, and React Native, but I choose the right tool for the job and I'm not afraid of unfamiliar ground. Above all I care about the experience: making products that feel delightful, accessible, and genuinely intuitive to use.
I don't want to be just an extra pair of hands. Clients keep me around because I help level up the whole team: planning solutions with product owners, thinking through hard problems with senior devs, and mentoring the people I build alongside.
Let's build something you're proud to ship.
A few projects I'm proud of
Kind words from people I've built with
Working with Daniel is extremely efficient and easy. He is fast, reliable and presents his comprehensive views clearly and constructively. He'd absolutely be in my dream team.
Daniel is a highly active and trustworthy developer, consistently delivering excellent work. His dedication and reliability makes him an invaluable asset to any team.
He communicated clearly about technical solutions and challenges, and gave me good suggestions I hadn't thought of. We met the project's goals and I would gladly work with Daniel again.
Daniel worked in a multi-vendor environment as our main point of contact. We greatly value his professional skills and can strongly recommend him for similar tasks.
We worked with Daniel for about a year. The collaboration was enjoyable. Daniel is a results-oriented, solution-focused, and self-directed developer.
Side projects, in the works
I'm building a handful of apps of my own, small products I actually want to exist. They're not quite ready to show yet.
