Hello, I'm

Mari Seppänen

Finland

I'm a software developer building things for the web. This is my corner of the internet, a work in progress.

I started working as a full stack developer in 2020. I work mostly with React, Next.js, TypeScript and Node.js, along with tools like Prisma, tRPC and AWS, building products from first idea to production and modernizing older systems so they're nicer to maintain.

Before the keyboard, I worked in a café and at a gym. Proof that useful skills don't only come from a keyboard.

<Focus />

  • Full stack work, from first idea to production
  • Modernizing legacy systems and cutting technical debt
  • Building products for the long term
  • Learning by building
