Miriam C.

Responsibilities:

• Developed the custom-fields mechanism of the Process entity, enabling fully dynamic workflows through a JSONB-based structure in PostgreSQL. Implemented the server-side logic and validation rules in .NET, built the REST API layer in NestJS, and created the data integration that allows each organization to define flexible and customizable processes.

• Implemented the Strategy Design Pattern to create a Kafka Message Dispatcher for routing messages, where each topic is directed to its dedicated handler. This architecture enables clean separation between microservices and smooth system extensibility.

• Developed a Load Testing mechanism in .NET to evaluate system performance under heavy load, including user-defined run counts, Smart Async Polling for DB-level result validation, and a queue-based execution flow to prevent parallel runs — all built in a modular and easily extensible architecture.

• Implemented the feature for linking existing documents to events, enabling reuse of documents such as syllabi, presentations, and guidelines across multiple events.

• Developed the capability to update custom-field values for an event participant, including validation logic and data persistence for the dynamic field structure, with a simple and user-friendly interface to perform the action.

• The solution was implemented within an event-driven microservices architecture with Kafka-based communication, running in a Docker Compose environment. Applied best practices with Git and Unit Tests, and completed multiple code reviews.
