Worked directly with the client to define operational requirements and design the application.
Built the Ruby on Rails and PostgreSQL application, covering appointments, inventory, invoicing, doctor commissions, and reporting.
Handled deployment on AWS using Docker and Kamal, followed by ongoing support and improvements.
Home visits, clinic appointments, and corporate services, with support for multiple patients, services, and follow-up visits.
Stock reservations, stock requests, and delivery notes across partners, warehouses, and pharmacies.
Invoice-service integration, manually recorded payments, doctor commissions, service costs, and financial reports.
Role-based access for operational teams, with dashboards and downloadable reports.
The application uses AWS and Docker, with Kamal for deployment. My responsibilities also include ongoing support and improvements.
The interface combines Tailwind CSS and Flowbite components. Turbo and Stimulus handle interactive updates, while ViewComponent organizes reusable Rails views.
Appointment progress and payment status are tracked independently. Ticket totals are recalculated when relevant data changes, rather than on every save.
Stock needs are calculated separately from stock reservation. Allocation follows the service type and can reserve stock for all remaining doses in a course.
Ticketing, stock, and invoicing actions use dedicated service objects with a consistent result format for success status, data, and errors.
Tests cover payments, stock, permissions, and reports. Selected tasks run as background jobs.
