Hello, my name is Markus Lehmann.

I am a senior mobile developer with backend expierence!

I am developing software for more than 16 years. In the last six years I have found my passion in developing mobile apps. Most of the time for Android.
I have worked for more than four years as a Senior Consultant in the Health Sector at IBM. I have done architectureal designs, development and several client integrations.

Back then my most interesting project was the electronic health record system known in Germany as „elektronische Gesundheitsakte“ (eGA) and „elektronische Patientenakte“ (ePA).

Flutter is the new fire in the Cross Plattform world. In the beginning of 2020 I started to develop AlarmBoard, a flutter app for the emergency sector. Our backend is hosted at AWS.
