In February 2025, Singano developed a WhatsApp Mock Development Feature for the Tanzania-AI-Community/twiga repository, focusing on backend and API development using Python. The feature introduced a configuration flag and a dedicated mock webhook endpoint, allowing developers to simulate WhatsApp interactions without sending real messages or performing outdated message checks. This approach streamlined development workflows by enabling safe, isolated testing environments and reducing integration setup time. The work demonstrated a clear understanding of configuration management and backend architecture, delivering a focused, testable solution that lays the foundation for broader mock capabilities and more efficient iteration cycles within the project.
