I worked extensively on the Legend Project to integrate multiple open-source applications into a unified system. The applications I worked with include:
Mautic: For marketing automation.
Metabase: For business intelligence and analytics.
Apache NiFi: For data flow management.
SuiteCRM: For customer relationship management.
OpenLDAP: For directory services and authentication.
Invoice Ninja: For invoicing and billing solutions.
NextCloud: For file sharing and collaboration.
GrayLog: For centralized log management.
I began by installing and deploying each of these open-source products individually, ensuring they were properly configured and secure. After the initial setup, I focused on integrating them according to the project's architectural diagram. This involved:
Configuring Data Flows: Using Apache NiFi, I set up automated data pipelines between the applications to ensure seamless data transfer and processing.
Integrating Authentication Systems: I implemented OpenLDAP to provide a centralized authentication mechanism, allowing users to have a single sign-on experience across all applications.
Connecting APIs: I connected the End User API as shown in the chart, enabling external systems and users to interact with our integrated platform.
Customizing Applications: I tailored each application to meet our specific needs, such as customizing dashboards in Metabase or setting up marketing campaigns in Mautic linked to customer data in SuiteCRM.
Implementing Security Measures: I ensured that all data exchanges were secure by configuring SSL/TLS certificates and setting up proper access controls.
Monitoring and Logging: With GrayLog, I established a centralized logging system to monitor application performance and troubleshoot issues effectively.
Collaborative Features: I set up NextCloud to facilitate file sharing and collaboration among team members, integrating it with other applications where necessary.
Financial Operations: Integrated Invoice Ninja to handle all invoicing and billing processes, linking it with customer data from SuiteCRM.
Throughout the project, I tackled various challenges such as compatibility issues between different software versions and configuring the applications to communicate over secure protocols. By the end of the project, I had successfully integrated all the applications, providing a cohesive and efficient system that enhanced our operational capabilities.
