Form Webapp (for pre-order) (integrating with payment platform or gateways) (in AWS)

Description: a webpage where potential customers can fill up a PO form based on stock/inventory and pay a deposit. We also have a payment platform that can be integrated, unless the developer can integrate with Indonesian payment gateways on its own. Code and design quality are important. Some points: - The green-colored window is our current payment platform that integrates with banks, e-wallets, and over-the-counter payments in Indonesia. - The database must be separated from the application, and both must be able to be deployed in AWS. - The database must be able to be connected directly to external visualization tools like Tableau. - The project is not complete until the app can be deployed on our own AWS. - All the text and pictures must be easily editable/changed. - Revisions until the web app is working as intended. - Code must be modular and self-documented. If not intuitive, further documentation is necessary. - Responsiveness and open communication are mandatory. - Testing and security are included in the project, and we expect the web app as bugless and robust as possible when handling random inputs or injection attacks. - Maintenance post-deployment is also included in case the server goes down. - This project is strictly confidential, and the developer will need to sign an NDA. Deliverables: - Source code - High-level architecture - Database schema - Deployment guidelines (in AWS) including all commands (also Docker and Kubernetes if any) - Database connection - Editing guidelines (for all the text and pictures) - API doc (if any)
