Alexandre developed the Merkl campaigns and pricing blacklists feature for the morpho-org/morpho-blue-api-metadata repository, focusing on backend and API development using TypeScript. He designed and implemented new data structures and backend logic to manage campaign-specific pricing rules and exclusions, enabling the codebase to support targeted pricing experiments and enforce blacklist policies. The work involved building robust mechanisms for handling dynamic pricing scenarios, ensuring that the system could flexibly accommodate future campaign requirements. Over the course of one month, Alexandre’s contributions provided a foundation for more granular pricing control, though the scope was limited to feature delivery without bug fixes.
