I implemented a cloud-based communication platform for a leading wine retailer and its 400 suppliers in order to optimize the wine harvesting processes (based on Kubernetes infrastructure and Spring-boot-based services). The project was implemented in cooperation with my partner Das Kellerbuch DKB OG whose systems were connected to the platform.

Conception, design and implementation of middleware for the efficient integration of software products from my partner Das Kellerbuch DKB OG to modern webshop solutions - with focussing on a cloud-based solutions and seamless on-boarding of new customers.

As part of this project, a Python-based backend application was designed and implemented for eologix-ping, one of the world's leading providers of rotor blade monitoring for wind turbines. Architectural focus: platform indendence, integration of backend systems, responsive UI design.

In addition to rotor blade monitoring of wind turbines the monitoring system of company eologix-ping supports lightning detection which offers additional value for the damage detection and root cause analysis. Scope of this project was to integrate the existing python-based application with an external 3rd party API for weather/lighting information, allowing to retrieve and use a large set of additional lightning parameters in the process, and to provide this information to users via notifications.

As part of this project, a Python-based backend application was designed and implemented for eologix-ping, one of the world’s leading providers of rotor blade monitoring for wind turbines. This application detects “events” (state changes) in system components, enabling eologix-ping and its customers to stay informed about the current status of the rotor blade monitoring system (e.g., ice detection). Key features include high configurability for tailored system adjustments, optimized access to firestore for increased efficiency and modular design for easy expansion, such as adding communication channels (beyond email), advanced templating, and more.

Over the years, I have contributed to multiple projects in the DACH and CEE region with IT companies specialized in the banking industry. My focus has been on investigation management across various financial domains, including payments, securities, nostro and loro. As part of these long-term collaborations, I have delivered software modules and professional services tailored to the needs of financial institutions. Working closely with IT providers and their banking clients, I have helped to enhance operational efficiency and compliance in critical business areas.
