Skills

After 17 years as a developer, 14 of them totally focused on iOS, I know myself well enough to say that I adapt pretty well to the continuously changing languages, frameworks and technology. I enjoy learning, improving and delivering good quality code.

For the past 7 years I have been working at MaaS Global (Finland), in a medium-sized international iOS team. We followed Scrum methodology, devops principles (CI/CD) and created SOLID code.

I especially like working on the UI, from design discussions to implementation. And being a freelancer for a decade has given me the expertise and knowledge to deal with team communication (also remote) and self-organize at the same time.

Based on comments from my previous CTO and team mates: I bring an air of calmness to the team thanks to my experience and my understated, methodological approach. I always find a way to get things done with quality and integrity. And I am also very loyal.

I worked on the latter with a teammate, developing it completely in Swift.
