Joe contributed to the OpenFn/adaptors and OpenFn/docs repositories, delivering robust data integration features and modernizing backend infrastructure. He engineered scalable API connectors for platforms like Salesforce, DHIS2, and MotherDuck, focusing on reliability, security, and maintainability. Using TypeScript and JavaScript, Joe implemented advanced AST manipulation for code analysis, improved bulk data operations, and introduced SQL injection safeguards. His work included overhauling adaptor APIs, enhancing FHIR resource builders, and refining documentation to accelerate developer onboarding. By aligning dependency management and release workflows, Joe ensured consistent, testable deployments, resulting in a more resilient, interoperable integration ecosystem for cloud and healthcare data.

October 2025 focused on delivering scalable data integration capabilities via the OpenFn/adaptors, with two major feature releases around MotherDuck integration and FHIR/Salesforce builder enhancements, plus stability improvements from tests and dependency updates. Implemented OpenFn MotherDuck Adaptor with SQL query execution, batched inserts, and table management, fortified by strong SQL injection validation. Launched Salesforce/FHIR Builder enhancements, including FHIR-4 builders for opencrvs resource bundles and related adaptor improvements. Upgraded dependencies (undici to v7.15) and refined release management with breaking tests fixes to improve deployment reliability. Result: safer, faster data ingestion and broader interoperability across MotherDuck, Salesforce, and FHIR ecosystems, with improved test resilience and deployment quality.
