Further development of a cloud-native microservice system for controlling intralogistics processes for a globally active corporation with C# (.NET 8) and Angular 16 (HTML/CSS/TypeScript).

▪ Conception and development of C# software modules for controlling automated guided vehicles (AGVs), including bidirectional communication protocols such as WebSockets and SignalR.

▪ Implementation of containerized performance tests using the Gatling framework in Java.

▪ Implementation of integration tests with C# and SpecFlow.

▪ Implementation and optimization of an ASP.NET Core microservice with Microsoft Orleans.

I spent most of my time at adesso on a large greenfield project where we implemented a cloud-native microservice system with orchestration by a process engine to map the end-to-end business process of a globally active corporation using C# (.NET 6) and Angular 13 (HTML/CSS/TypeScript). In this role, I took on architectural tasks, led an agile sprint team, created cloud workloads and CI/CD pipelines, and performed implementation tasks. In my last project at adesso, I took on the role of software architect, conceptualized the software according to Domain-Driven Design, and designed and implemented the Azure environment, including pipelines and integration with MS Graph and Azure AD.

▪ Creation of a domain model based on business stories and in cooperation with the client.

▪ Conception and implementation of the backend architecture (ASP.NET Core Web API with CQRS and MediatR).

▪ Creation of the rollout concept and implementation as Azure Pipelines with YAML templates and PowerShell.

▪ Team leadership of a temporarily 8-person development team, including sprint preparations and refinements.

▪ Implementation of business stories in the backend.

▪ Setup and coordination of Azure environments with App Service, Static Web App, Key Vault, and OAuth2 configuration.

▪ Implementation of application integration with Outlook, SharePoint, and Planner via Microsoft Graph.

At Safelog, I implemented and largely managed a diverse range of software projects focused on the company's product portfolio. This primarily involved control systems for logistics facilities and mobile transport robots, or a combination of both, and their integration with customer systems of major German automotive manufacturers and their suppliers.
