- Optimization of search performance (Mongo Atlas Search, Geospatial queries)

- Creation of a microservice for bulk export of product documentation related to one or more user orders (hexagonal architecture, Java 11, BPMN workflow, Zeebe, Azure container storage, Coremedia)

- Study of a solution for tracking account activation emails sent to users via Sendgrid. Documentation of the solution on Confluence.

- Study and implementation of a solution for dynamic management of forms created via the Coremedia CMS (GraphQL, Java 11).

- Performance testing: Definition of scenarios via Gatling, execution of scenarios via Gatling Cloud, and analysis of response times based on the number of deployed pods. Analysis of JVM memory consumption with Dynatrace. Writing reports on Confluence and brainstorming improvements.

- Debugging issues related to Azure Event Hub (Kafkacat, Redpanda (Kowl))

- Code review

- Ticket estimation

- Demonstration of features at the end of the sprint

- Participation in agile rituals (PI planning, Sprint planning, Refinement, daily meetings, bug reviews)

- Deployment of microservices on test and production environments on Azure cloud and bug resolution.
