Project history
NDA!
New development of an internal tool for the management, configuration, analysis, and monitoring of different data migration jobs and tasks. Data is extremely important for daily business operations. The frontend enables searching, filtering, sorting, monitoring, and viewing configurations and logs. Further features include configuring, scheduling start- and routine executions, as well as defining relationships and dependencies between different job and task types.
My Tasks
Solo new development of a SpringBoot application: Backend and Frontend
Architecture of the new development
JUnit Tests and integration tests
Database optimization
Knowledge transfer
Consulting
DevOps

Completion of my service and handover
Ensuring full coverage of specification and quality in a complex setup with many microservices.
Further development of the test infrastructure with simulator and mock services for local Minikube and Cloud Kubernetes environments. In addition, definition and implementation of test specifications.
The landscape for the application to be tested is modeled with over 14 microservices. The System Under Test is a new development for a nationwide deployment that just about everyone will come into contact with it indirectly.
Configuration and specific scripts of the GitLab CI/CD pipelines and Kubernetes. Encryption and code obfuscation. PKI, Certificates

Consulting and optimization of existing software and development processes.
My contribution to improving the portal product from Beta Systems lay in well-founded analysis and measurements with data of varying complexity. My goal was to optimize the performance of the SQL queries and the interface between the backend and the database, as well as answering open questions about the architecture, libraries and solving complex challenges. In ad- dition, some of my advice was for the development process, organization and working with customers.
