About Pascal Welsch

Hi, I’m Pascal Welsch, a Software Engineer working as freelancer with focus on mobile applications.

After 6 years of professional Android development my passion shifted towards Flutter where I can build apps for multiple platforms. As Google Developer Expert for Flutter, I speak at conferences, build open-source projects and write blog posts about my learnings.

I love building stunning user interfaces and fluid animations. But I feel the same passion when I build SDKs, libraries, tools or business logic in a test-driven manner.

I used to work as Android team lead acting as a coach, not a manager. This role allowed me to give honest feedback and share knowledge in code reviews, pair-programming sessions and in regular coding dojos.

I’m currently living in Cologne, Germany. If we’re lucky and meet at a conference I’d be happy to have a chat with you!

Favorite projects

“The biggest reward for my open-source projects is when I see others using them to solve their real-world problems.”

– Pascal Welsch

kt.dart

This project is a port of Kotlin’s Standard library for Dart/Flutter projects. It's a useful addition to dart:core and includes collections (KtList, KtMap, KtSet) as well as other packages which can improve every Dart/Flutter app.

Tray

A SharedPreferences replacement for Android which supports multiple processes and versioning.

ThirtyInch

A MVP library for Android which adds a Presenter to Android Fragments and Activities (View). The View is hidden behind an interface allowing unit tests. The Presenter survives configuration changes similar to ViewModels as part of Architecture Components.

Git revision

A git extension which calculates a version number based on the commit count. Executable as shell script or gradle plugin.

Flutter Wrapper

Cross platform shell script to execute Flutter projects which downloads and updates Flutter on demand.

Konduit

An experimantal declarative UI Framework for Android. It binds Android Views to a DSL defining their properties. Definitely far behind Jetpack Compose.
