Worked on digininja/theHarvester to consolidate external API services by introducing the AdditionalAPIs class, centralizing domain information gathering and reducing code duplication. Refactored existing API endpoint functions to leverage this new abstraction, which improved maintainability and streamlined the process for integrating new APIs. Prepared the codebase for secure future integrations by adding a placeholder for API key authentication. Addressed a docker build error to stabilize the build pipeline and enhance CI/CD reliability. The work focused on backend development and API integration using Python, emphasizing architectural clarity, maintainability, and scalability while laying groundwork for more robust external service management.
