Badeesorn Sitthiwong developed and modernized the payments infrastructure for KMUTT-CampusLink, focusing on both backend and frontend improvements across the campus-server and campus-client repositories. She implemented end-to-end payment processing with Stripe integration, installment plans, and automated invoice management, using Node.js, Express.js, and Prisma ORM to ensure secure, reliable transactions. On the frontend, she enhanced the React-based payments platform with centralized API data, improved UI/UX, and clearer transaction states. Badeesorn also addressed backend reliability by ensuring accurate payment date tracking, which improved financial reporting and reconciliation. Her work demonstrated depth in API development, authentication, and payment workflow design.

In December 2024, KMUTT-CampusLink/campus-server delivered a critical backend reliability improvement to financial tracking. A bug fix ensures that paid_date is captured whenever an invoice or installment is marked as Paid, improving revenue recognition, reporting accuracy, and reconciliation workflows. This change was implemented in useWallet.js (commit 72d62b11a5e79d2f9dea034e62bed6e65e4f3c54) and validated with standard checks. No new user-facing features shipped this month; the focused delivery strengthens financial data integrity and lays groundwork for enhanced payment analytics and automated reporting.

November 2024 performance summary: Delivered end-to-end payment capabilities and a refreshed payments experience across campus-server and campus-client, enabling reliable Stripe-based transactions, installment plans, and automated invoice lifecycle, underpinned by strengthened security and a polished user interface. Key efforts included backend Stripe integration, installment/invoice status management, and auto-cancel of overdue invoices; security enhancements such as enforcing access tokens on payment routes and implementing a local JWT approach. On the client, modernized the payments platform with centralized API data, enhanced invoice/installment listings, and UI/UX refinements (currency formatting, status labeling, and smoother redirect flows). A notable bug fix improved transaction list rendering, showing clear states when no invoices exist and simplifying user actions for unpaid statuses. These changes collectively improve cash flow visibility, reduce failed payments, and deliver a more robust, scalable payments experience for both users and operators.
