Worked on the OpenCTI-Platform/connectors repository to deliver extensible data ingestion and export features focused on improving threat intelligence workflows. Developed an internal-export connector enabling OpenCTI data selections to be exported as OpenDocument Spreadsheets, enhancing data accessibility and analysis. Introduced external-import connectors for Mattermost channels, Intel 471 darknet alerts, and Matrix homeservers, allowing ingestion of threat data as STIX 2.1 objects. Enhanced VirusTotal Livehunt Notifications with malware configuration extraction and processing controls. Leveraged Python, asynchronous programming, and Docker to implement robust backend solutions, emphasizing API integration, data processing, and unit testing to ensure reliability and maintainability throughout the codebase.
