TripInBlink — Travel Marketplace Platform

Travel marketplace connecting tourists with verified local tour guides, built as a Turborepo monorepo with three React 19 portals and a PostgreSQL backend.

The Problem

Travelers struggle to find trustworthy local guides, and independent guides lack a platform to list packages, receive requests, and get paid.

The Solution

Built a marketplace with separate portals for tourists, guides, and admins, backed by a clean-architecture Express API and a normalized PostgreSQL schema.

Key Capabilities

Tourist portal: global search, multi-currency pricing, package catalog, verified guide directory, and a custom itinerary wizard.
Guide portal: earnings wallet, package builder, KYC document upload, and bidding on open tourist requests.
Admin portal: revenue and platform-commission analytics, user analytics, and a guide KYC approval queue.
Clean-architecture API (controllers, services, repositories) with JWT auth, RBAC, rate limiting, Zod env validation, and Pino logging.
Normalized PostgreSQL schema with 25+ Prisma models.

Lessons Learned & Key Takeaways

TripInBlink taught me to structure a large monorepo with shared types across apps, and to design a marketplace data model with roles, KYC, bookings, and commissions.
