Experience

CRM System

I developed a CRM system that helps my client reduce his work time by enabling him to track all the sales processes of his employees including reporting and management functions. I handled the whole project on my own.

Code Signing as a Service

I developed a software application that guides you through an automatized rule- and role-based code signing process (Authenticode and others).

I handled the requirements engineering as well as planning the architecture of this application (event-sourced, CQRS). The whole project was implemented test-first and we used practices from domain-driven design (DDD) such as domain storytelling und ubiquitous language.

Software for Brokers

I developed a type of software for a banking client which is used for brokers to calculate building society loans. I implemented the regulatory parts based on the requirements engineering that I did beforehand, which included handling of different rules based on each federal state of Austria.

Control Software for Timber Drying Plants

In a team of four, we created a new type of software that visualizes and controls the process of wood drying. I implemented the so-called drying-program-management which defines parameters for each stage of the timber drying process such as regulating heating and ventilation based on humidity and other sensor data.
