// 01.PROBLEM_DEFINITION

Local vendors lacked a professional, secure platform to handle digital transactions and post-purchase customer communication.

// 02.IMPACT_METRICS

[1]

Integrated eSewa and Khalti payment APIs with secure webhook verification logic.

[2]

Automated post-purchase workflows: dynamic PDF invoice generation and instant email dispatch.

[3]

Built a real-time order tracking system synchronized with a Node.js backend.

// 03.ARCHITECTURE_RECAP

Engineered a marketplace focused on trust and conversion. The key technical win was the automated document engine using Puppeteer, which generates and dispatches professional invoices the millisecond a payment is verified via webhook.
