Professional Community Portal

A Salesforce community that I built for medical professionals to access their patient's health records, manage the patient's orders, and arrange the remote checkup. I also delivered the provisions for registering and onboarding new patients in the system. My other contributions include:

• Implementing the Salesforce IDP for external users' portal access and onboarding process workflows.
• Developing the Salesforce custom REST APIs to be consumed by external systems or apps hosted on the AWS platform.
• Provisioning for users and uplifting user types based on criteria, matching and merging the records, such as accounts and contacts, using the Demand tool.
• Designing multilingual email templates based on the user's geographic location.
• Synchronizing data between different systems using ETL tools.
• Integrating to show external data in Salesforce using external objects.
• Implementing the approval workflows for the registration process of professionals and clinic managers.
• Building some batch processes to monitor and clean up provisional records from the system for system hygiene.
• Deploying CI/CD to higher environments.

Case Management System

A case management system that I developed for managing and tracking issues/incidents. Customer/professional feedback emails are sent to the organization based on regions and types. I created the Salesforce case with record types, assigning the case to the relevant service team's queue based on the email origin and type. Once the case is created in Salesforce, it also creates an incident in the external incident management tool to track the progress of issues and send emails to members of the queue on case creations.

Integrated Fleet Services Management System

An integrated fleet service management system that captures incidents, faults, and defects of the trains associated with each fleet. I developed the portals for rail management to interact with integrated systems like TIBCO and SAP. The system is built using Java and JSF on the IBM Websphere application and portal server.
