Designing and developing multi-tenant infrastructure architecture that can easily scale over multiple accounts. Each account can host multiple environments and applications which are logically separated, standardized and secure. Solution must include defined security features, automated backup and allow for faster disaster recovery and account switching. Also the solution must be cloud provider independent in case the cloud provider must be changed.
- Design of the new solution
- PoC of the solution
- Automation of the deployment
- Application migration
- Infrastructure as code
Project description:
Designing and developing infrastructure and custom solution for automated test data generation and test execution. Custom solution included a system that allowed developers and testers to defining test cases and data templates throught web UI which are used to generated test data and prepare testing environment. When the test date is ready, a CI/CD pipeline starts to execute tests and alerts users if tests fail.
The aim of the project is to transfer the PeopleSoft HCM application from the on-premise data center to the AWS Cloud. With this historically grown and strongly adapted application, the approximately 200,000 employees of DB are managed. For this purpose, the new infrastructure is to be made available automatically in accordance with DB Systel and AWS best practices standards, and the application with data is transferred to the cloud. The high security requirements with regard to personnel data must be observed.

Developing backend and supporting infrastructure for e-mail campaign service. Service will act as user frontend for defining and controlling campaign?s, receiver?s and page/e-mail design. Also, it must have endpoint?s for tracking e-mail and link?s as well as receiving notification?s about e-mail. Campaign flow logic and processing will be offloaded to aWF for greater stability and responsiveness.
- Requirements analysis
- Backend development
- AWS SES integration
- AWS SNS integration
- Development pipeline
- Customer supportDevelop multy-account environment for software development and deployment. All account?s must have consolidated billing and cross account access over private network. External access to private network is allowed only through VPN, and role level access control must be implemented for AWS resources.
- Requirements analysis
- Account design
- CIDR block?s
- Access control
- Cross account access
- Consolidated billing
Migrate all services from .NET to Java (Spring Boot). Due to the requirement for scalability and high availability as well as the support of third-party systems, the decision was made to transfer all projects to Java. With micro-service architecture, existing systems are supposed to be seamlessly updated to the Java runtime environment. The services are operated as Docker containers in a Kubernetes infrastructure with automatic scaling and load balancing.
The monolithic AWF application has been expanded over the years until it recently became difficult to maintain, so the decision was made to split applications into microservices. The new design consisted of the Authority service for SSO with OAuth2 and OpenId Connect, the Framework API as a REST service, the web portal for user interaction, the Workflow Designer desktop application and additional plug-in services. The MS SQL database has also been replaced by the MongoDB database without SQL.
Project description: Taking over as lead developer for the entire aWF. Redesigning the user interface for desktop and web applications with user experience as a priority. The web application was rewritten with the MVC concept and responsive design. DevExpress controls have been replaced with internally developed controls for desktop and web applications.
Developed a .NET web forms application and a MS SQL database. The web application is a user interface driven by the MS SQL engine.
