Experience

Cuckoo | Framework

https://github.com/SwiftKit/Cuckoo

Cuckoo is a boilerplate-free mocking framework for Swift.

As Swift does not have reflection functionality, mocking of Swift classes and protocols is impossible without a little help. Either a developer has to write those mocks himself, or have them generated by Cuckoo. It also comes with a powerful DSL for stubbing and verifying calls. I came up with the initial idea and then implemented it.

Tootoot | App

Tootoot is kind of a social network for musicians and their fans (and venues, managers, etc.) and my responsibility was to develop the iOS application for the project. I worked about 10 months on this project and it was great experience.

GoMentor | App

GoMentor is a service for video-calls between mentors and clients.

I was asked to fix numerous bugs before the app's deadline as the client was not happy with the previous developer. I quickly analyzed the code base and managed to fix all the blocking issues to meet the deadline. After the release, I made a few more improvements to ensure the best user experience.

Reactant | Framework

https://github.com/SwiftKit/Reactant

Reactant is a Swift framework, bringing React-like behavior to UIViews and UIViewControllers (called components).

It eases some pains of iOS development. Every component has a type-safe state and gets re-rendered each time the state changes, ensuring predictable behavior of the components and thus the application.

Febiofest | App

Febiofest is a film festival in Prague for which we developed Android and iOS applications.

I led the two teams, one for each platform and was communicating with the client. This project was rather challenging as we were limited by time as we needed to get the app ready before the festival began.

NetMonster | App

https://play.google.com/store/apps/details?id=cz.mroczis.netmonster

NetMonster is an Android utility application showing information about network status.

I was a technical adviser on this project, helping the developer choose the right libraries and architecture.
