Lincoln Chumba developed core features for onaio/fhir-tooling and opensrp/fhircore, focusing on automation and AI-driven data capture. For onaio/fhir-tooling, he built a CLI command to batch-update FHIR server location lineage, integrating authentication and FHIR API client setup, and established shared utilities and test dependencies to streamline development. In opensrp/fhircore, he delivered AI-powered audio transcription for FHIR QuestionnaireResponses, combining Google Cloud Speech-to-Text and Gemini models to automate structured data entry from live speech. His work leveraged Kotlin, Java, and dependency injection, demonstrating depth in FHIR data modeling, robust error handling, and test-driven development for scalable, maintainable healthcare solutions.

May 2025 monthly summary for opensrp/fhircore: Delivered AI-assisted audio transcription to FHIR QuestionnaireResponses, enabling live speech-to-text input and automatic conversion of transcription text into structured FHIR data. Implemented robust error handling with retries in the AI-driven conversion path and integrated Google Cloud Speech-to-Text for transcription with Gemini models for FHIR data mapping. The feature is designed to accelerate data capture, reduce manual transcription errors, and improve data quality in clinical forms. No major bugs logged this month; groundwork laid for scalable AI-powered data capture in form workflows.
