Alexandre developed the Merkl campaigns and pricing blacklists feature for the 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 blacklist enforcement. The work involved building robust mechanisms for handling dynamic pricing scenarios, ensuring that the system could flexibly accommodate future campaign requirements. Although the project scope was limited to a single feature over one month, Alexandre’s contribution addressed a clear business need and laid the groundwork for more granular pricing control in the platform.
