Yannick Müller

Verified Expert  in Engineering

Artificial Intelligence (AI) Developer

Bonn, North Rhine-Westphalia, Germany
Toptal Member Since
March 7, 2016

Yannick has been a programmer for more than 10 years. He trained as a mathematical and technical software developer and has studied artificial intelligence. You could characterize him as a full-stack developer with a preference for back-end work. He's strongest in C++, Java, and C#, but he also has a fair knowledge of many others: C, Python, Django, JavaScript, Lua, and Bash. He's punctual, flexible, and works until the job is done.



Preferred Environment

Qt Creator, Git, Eclipse, Linux

The most amazing...

...thing I had to implement from scratch was a simultaneous localization and mapping algorithm where a robot has to autonomously create a map of its environment.

Avionic Configuration Software

I developed a configuration platform for aviation products. I also designed a generic configuration tool with a shared IO, data structure, CLI, and GUI (C++/Qt). I used plugins to handle product specific data dependencies and UI elements and implemented a plugin for one product.


I built IHNP which is an application that collects and processes data from different gaming platforms; it has a desktop UI written in GTK+. It required some reverse engineering of incompletely documented public APIs, conversion of platform specific data into an independent data structure, and zero trust encryption of sensitive data.

picturemaxx Rendering Network

I created a new high-performance system and infrastructure for queuing, load balancing, and processing of expensive and asynchronous tasks such as image and video rendering.

my-picturemaxx 5.0

I developed a new version of the media search engine my-picturemaxx. I used the client-side C++ Qt UI as well as hybrid HTML content. The data communication used custom SSL certificate management, white box encryption, and XML.


A library for creating long scrollable widgets with millions of elements.


A computer clone of the board game Carcassonne created to research about the Monte-Carlo Tree Search.

Language Identification

A library for detection of multiple natural languages within one input document.

Hotel Matcher

Software that automatically maps a large amount of hand-input hotel client data to internal data that's based on only a few, non-normalized properties.


Software for the fast-parsing, analysis, and categorization of large log files on many remote servers without needing to download the files.

Statistical Communication Analysis

A framework for statistical analysis and detection of irregularities in communication with different client infrastructures.

Vision Desk

Software for travel agencies for inspiring customers and booking trips using the first commercially available multi-touch computers.
