Android Freelancer
from Leipzig

Hi, I'm Robert Hilse!
As an Android App Developer I realize Android Apps
for customers who love native and sustainable solutions.

Robert Hilse – Android App Entwickler aus Leipzig

Your expert on Android Apps

I have been passionately programming Android apps for smartphones since 2012.

As a perfectionist, I attach great importance to high-quality source code. With the latest technologies I implement demanding requirements.

Your hero for users

I always think ahead! When I’m implementing or testing  apps, I see it through the eyes of the user.  

Intuitive handling, attractive app design and an extraordinary added value enables an app to become customer’s favourite.

Your agile team player

Communication in a team is the most important thing for me. Especially in agile teams the steady interchange is neccessary.

Changing requirements? No problem! Flexible, organised and with the right sense of humor I manage any demand. 

My aspiration as App Developer:

Who stops becoming better, stops being good.

Agile App-Flow with Jira! Confluence! Scrum!

Agile App Developement means, that I can react flexibly to your requirements. Whether Scrum, Canban or Scrumban – I adapt to your process. Problems that occur during the development process, I address openly in the team and propose solutions.

And as the saying goes: In the end problems are solutions, we work out in the team!
