MVP app for shock logger to monitor and analyze transport data via BLE as a Kotlin Multiplatform solution for Android and iOS.

Reduced time-to-market by optimizing CI/CD pipelines. Employees without customer VM access can now deploy. Increased system stability and performance and reduced maintenance effort through systematic database cleanup. Restricted rights for Flyway migrations versus service users. Improved transparency and decision-making basis with enhanced Grafana dashboards for response times, optimized logging, and standardization with Loki. Reduced security risks by consistently applying security best practices such as removing the public schema in PostgreSQL, individual service user permissions, and Docker security context. Facilitated knowledge transfer and sustainable process improvements by creating process diagrams and implementing various concepts. Conducted code reviews across multiple repositories.
