Leevi Puntanen — Full Stack Developer

I build and ship web apps that stay fast, intuitive, and easy to maintain. Most recently, I delivered customer-facing features and backend APIs with Next.js, Node.js, and PostgreSQL.

Experience

Production work and foundations.

About

Straightforward software and clear UX.

I design and build web applications with maintainable code, clear user flows, and predictable performance. I prefer simple solutions that stay reliable over time.

At Dream On Networks Oy, I ship full-stack features using Next.js, Node.js, Prisma, and PostgreSQL. I'm also building StriveAI, an adaptive training app powered by real usage data.

I study computer science at the University of Helsinki and keep refining my tooling, automation, and deployment practices to move fast without sacrificing quality.

Architectures designed to be easy to extend and maintain.

Interfaces that stay clear, fast, and free of clutter.

Performance and reliability measured, not assumed.
