Petri Kainulainen

Petri Kainulainen is a Finnish software developer who is specialized in software development with the Spring Framework. He got his first computer as a Christmas gift when he was eight years old. A few months later he "wrote" his first computer program by copying the code from the user's manual of his Commodore 64.

At the time Petri had no idea what he was doing but the outcome of his work amazed him. He wanted to learn more about this thing called programming. In a way, that moment was the starting point of his career.

Petri has over a decade of experience in software development, and he has participated in the development projects of Finland's leading online marketplaces as a software architect. Currently he is working in a privately owned software company, where he concentrates on adding value to customers and learning new things every day.

By the way, Petri no longer practices copy and paste programming.
