Julien contributed to the morpho-org/morpho-blue-api-metadata repository by modernizing API metadata, consolidating oracle feeds, and enhancing cross-service data integrity. He introduced structured token and vault whitelists, implemented migration tooling, and improved documentation to streamline onboarding and governance. Using TypeScript, Go, and JSON, Julien developed migration scripts for unified data outputs and ensured deterministic CI builds in the morpho-org/sdks repository by freezing pnpm lockfiles. He addressed integration issues by temporarily removing HyperEVM tokens to maintain API reliability. Julien’s work demonstrated depth in backend development, data modeling, and configuration management, resulting in more robust, maintainable, and secure API infrastructure.

Month 2025-10 focused on stabilizing HyperEVM token integration within the morpho-blue-api-metadata service. Implemented a temporary removal of HyperEVM tokens to mitigate ongoing integration issues and maintain API reliability. Established a plan for investigating and fixing the HyperEVM token integration in a subsequent release.

February 2025: Delivered Oracle Vaults Whitelist feature for morpho-blue-api-metadata, introducing a JSON-structured whitelist to restrict oracle interactions to approved vaults; included a fix to ensure correct JSON format for the whitelist. This change enhances security, governance, and operational reliability of oracle data flows.

January 2025 performance highlights: Delivered comprehensive Morpho Blue API metadata modernization, consolidated oracle feeds, and strengthened cross-service data integrity, with CI improvements for reliable builds. Key work across morpho-blue-api-metadata included token whitelist and address normalization, vault whitelist data structure, and migration tooling; Oracle data consolidation produced unified all-feeds.json and all-tokens.json; metadata cleanup aligned with main API and removal of unused price_feeds field; migration tooling and improved docs to boost onboarding; and, for the SDKs, deterministic CI builds via PNPM lockfile freeze.
