About Gerli

I help healthcare organisations modernise data systems, improve interoperability, and turn complex requirements into implementable solutions.

I specialize in translating complex clinical, regulatory, and business requirements into clear, implementable solutions. My core expertise includes HL7 FHIR, healthcare interoperability, and health data architecture.

I have worked extensively with large-scale, event-based data exchange solutions and national infrastructures, supporting the transition from document-based to structured, real-time data flows. I am experienced in bridging the gap between clinical stakeholders, business teams, and technical developers.

Key areas of expertise:
• Business and system analysis (requirements, user stories, workflows)
• HL7 FHIR modeling and implementation support
• Healthcare data standardization (ICD, clinical data structures)
• Interoperability and system integration (incl. X-Road environments)
• Data-driven service design and event-based architecture

I bring a strong combination of domain knowledge in healthcare, analytical thinking, and practical experience in delivering complex system changes.

I am particularly interested in projects related to healthcare systems, digital health transformation, and data-driven decision support.

Available for remote and international projects.

Open to both short-term advisory and long-term collaboration.
