About Lennard

I am a software developer working mainly in Flutter, which is my favorite framework at the moment. Flutter gives me the ability to quickly convert design / ideas into working applications and features.

My mobile development journey initially started with my initial try-outs on native Android and iOS, for which I built my first, and most-successful app Labda - eventually having more than 300k downloads.

I started further developing myself in the field of app-development / ad-tech and product development and began working more professionally on various projects.

Currently, I have shifted my focus to cross-platform development by making use of the Flutter framework, which I am doing now for about 4 years. Next to Flutter I have an interest in Web3, having written my bachelor thesis about "User experience in Web3 wallets", and open to develop myself more in this field.


Primarily located in Malaga (Spain) / Driebergen, Utrecht (The Netherlands), optionally available for hybrid arrangements.

Experience

  • Breeze - Offline dating

    Breeze is a unique dating concept that emphasizes taking online dating offline by arranging real-life dates after their users filled out a date picker. They counter the endless swiping and chatting by only sending a small set of profiles. If two user match, the app arranges a date in one of the partner bars.

    The app started in the Netherlands, and is now active in Germany, Belgium and United Kingdom as well, having organized over 150k dates.

    In my role as a Flutter developer I was active in agile team consisting of 3 developers, building new features, converting legacy codebases to architectural standards and ensure code quality by automated testing.
