Radovan Tomasik led the development of negotiation and governance features for the BBMRI-ERIC/negotiator repository, focusing on robust backend workflows and user-facing improvements. He engineered secure API endpoints, advanced form and template management, and streamlined notification and analytics systems using Java, Spring Boot, and Vue.js. His work included data integrity enhancements, PDF and CSV generation, and comprehensive test coverage, addressing both business logic and UI reliability. By refactoring legacy code, modernizing deployment pipelines, and improving observability, Radovan ensured maintainable, scalable solutions. His technical depth is evident in the integration of authentication, authorization, and internationalization, supporting complex, production-grade workflows.

January 2026 — BBMRI-ERIC/negotiator: Implemented two key feature streams to boost negotiation management and testing reliability. Features delivered: Negotiation Display ID and Search Enhancements (human-readable display IDs with admin editing, automatic generation, and search by title, ID, or display ID) and Negotiation Test Data Seeding and Migration Reversion (seed data for biobanking negotiations and revert test data migration changes to maintain compatibility). Major fixes: auto-generation of display IDs and migration rollback. Overall impact: improved negotiation traceability and searchability, faster admin workflows, and more robust test environments with preserved backward compatibility. Technologies/skills: backend data modeling for IDs, automated ID generation, search parameterization, test data management, and migration rollback with test coverage.

December 2025 (BBMRI-ERIC/negotiator) delivered key backend stability improvements, improved user experience for negotiation payloads, and a critical CORS fix. The team consolidated and upgraded backend dependencies to remove outdated libraries and restructure the dependency graph, leading to more reliable builds and better performance. User-facing improvements standardized newline formatting in negotiation payload views for clearer display. Additionally, a CORS configuration fix for the /v3/requests endpoint, along with updated tests, improved cross-origin request handling and integration reliability. These efforts reduce technical debt, shorten release cycles, and strengthen our API compatibility with client applications. Demonstrated proficiency in Java, Maven, REST APIs, and frontend-like formatting considerations, with a clear focus on business value: stability, readability, and reliable cross-origin access.
