Short Bio

My name is Marin Todorov and I am an independent developer and publisher. I work exclusively on iOS projects since late 2009. At present I get busy with a healthy mix of contract work, writing, developing open source software, and speaking/workshops or in-house trainings for companies.

Find a showcase of my favorite projects below or head to LinkedIn for a more detailed overview of my professional experience.

Apps

I've worked on more than 15 apps - both for clients and own independently published projects.

I have a small studio called Underplot Apps. Me and my graphical artist released about 10 small apps in the first years of the app store. Some got traction and got us started on the App Store.

These days we rarely work on our own ideas, we mostly do contract work for clients if their project feels right.
