Mumbo — Pilgrimage Travel Booking

Pilgrimage package bookings had no self-serve online path and no structured way for administrators to review and approve requests before payment.

What I actually owned.

Built the React.js frontend and Node.js backend APIs; built the admin dashboard and payment validation logic.

Components

How they connect

Bookings enter as pending requests; the admin dashboard drives approve/reject before a booking is confirmed and paid.

Admin approval step before payment confirmation

Package availability for sacred pilgrimage slots needed a human check that a plain self-serve checkout would have skipped.

Code-splitting and lazy loading across the booking flow

Mobile users browsing packages needed fast page loads on the primary conversion path.

Performance work

Validating booking transactions cleanly through a third-party payment gateway.

Implemented validation logic around the payment workflow so failed or partial transactions couldn't leave a booking in an inconsistent state.

Keeping the booking flow fast across mobile, tablet, and desktop for a broad, non-technical user base.

Used code splitting and lazy loading to keep the critical booking path light on mobile networks.

A car rental agency needed to move off manual, phone-and-spreadsheet bookings to a real-time online platform — built and run solo.

An insurance quotation platform needed to scale past a monolithic frontend as more product lines and teams shipped features in parallel.
