OTA b2c & Dashboard Design

Front end : Next js= Back end : Node js

I am rolling out an OTA platform built around independent modules. The very first milestone is a fully working eSIM & insurance module that plugs into our core and speaks to the specific APIs we will give you. All subsequent features—insurance, visa, Umrah and holiday bookings—will reuse the same architecture, so clean, maintainable code is essential.

Here is the current setup:
• A finished B2C user-side design in Figma.
• No admin interface yet—this needs to be designed and implemented alongside the eSIM work so we can manage plans, users and transactions from day one.

What I need you to deliver:
1. End-to-end eSIM (API) integration using the exact endpoints and auth flow we provide.
2. Front-end implementation that follows our Figma B2C screens pixel-perfectly.
3. A new admin dashboard that mirrors the same design language, lets us add / edit eSIM plans, activate SIMs, view usage and export reports.
4. Clear, well-documented code and API notes so the next modules can drop in without refactoring.

Acceptance criteria:
– Successful purchase and activation of an eSIM through the live API in a staging environment.
– Admin can create, modify and disable plans, and see real-time status.
– All screens responsive and consistent with the provided Figma file.
– Codebase includes README and endpoint documentation.

If you have solid experience with OTA platforms, API-driven products and designing admin dashboards, I’d like to see your approach and timeline.
