Hi, I'm David.

Building sophisticated software solutions and being part of great teams is both, my passion and my profession. I'm excited about coding, blogging, open-source stuff, the dev community, conferences, books and many more. I'm currently based in Vienna.

More About Me

I support teams in the Enterprise Environment to build Angular Applications that scale:
Advanced workshops about Angular Architectures, Best Practices, Design Concepts and Performance Patterns.
Code Reviews
A codebase deep-dive to make sure that you’re on the right track, combined with lots of knowledge sharing.
Supporting your teams and projects for a longer period to get things done and to guide you to future-proof solutions.


I'm a regular speaker on international conferences. Some of my work can be found here:

I'm blogging about a couple of things, but most of them, in one way or another, are related to software engineering.

Other stuff i do

Beside my daily business, I enjoy to support the local community or to kick off some side-projects with other enthusiastic people. A selection:

Developer Melange

A monthly podcast which brings you regular discussions about software engineering topics. All of them, in one way or another, related to building great software products.


Nobt.io is a free service that solves the tedious task of splitting several bills among your friends with ease. It's open-source, easy to use and available everywhere.

Vienna Coding Dojo

A coding dojo is a get together of programmers of any experience level to work on a small exercise. It provides a safe environment to tackle topics ranging from clean code over software design.
There are a lot of more things to share. If you are interested check out github.com/duffleit or just search the web.
