Lead Developer


Sep 2013 - Oct 2018, 5 years 2 months

A great experience which taught me a lot about architecture, CI, servers and microservices, and moving towards the future with restrictions of legacy, always finding ways forward.

I was the lead developer of Richie’s digital publishing iOS app platform, products and SDKs, and also helped with the Android version. I helped SDK customers with technical integration and possibilities of app platform and SDK products. In addition to product development, I did iOS and Mac development consulting for big and small projects and clients.

As a lead developer I improved Richie’s CI, CD, automated testing practices, code quality and architecture designs. I also planned and designed projects, architectures, systems and products.

Lead Cocoa Developer

Marko Karppinen & Co.

Nov 2003 - Aug 2013, 9 years 10 months

A once-in-a-lifetime opportunity to do consumer Mac app development for multiple years, and learn all about Mac, and jump to iOS and learn all about it.

I was part of team creating a pretty big consumer app for the Mac with a lot of functionality under the hood, including file management, device communiation using USB and Bluetooth and a rich UI.

When iPhone came along, we jumped right into iOS consulting for multiple clients and I think I did a pretty good job at that as well.

Employment carried over to Richie.

A great experience where I learnt a lot from a driven entrepeneur. Sales-orientation and helping customers were an essential part of the job.

I continued developed and improved the architecture of a networking monitoring tool, integrating various Linux tools and added custom logic with Perl, shell scrips, Java, and C. I got to learn and become very familiar with IP networking and equipment (routers, switches).
