Passenger ticketing & cargo logistics / CASE STUDY
Bus Bay
A bus ticketing and cargo platform connecting passengers, terminal teams and conductors through booking, payments, QR tickets and package handoffs.
01 / OVERVIEW
Bus Bay brings passenger booking and terminal cargo workflows into one multi-company platform. A Rails 7.2 modular monolith provides the JSON API, passenger web experience and ActiveAdmin console, while one Expo application serves customers, staff and conductors.

Passenger and operational experiences
Booking, payment and trip workflows
One business layer across web and mobile
Scoped operational permissions
02 / PROBLEM & WORKFLOW
Cargo handoffs, made traceable.
A package crosses cashiers, departure teams and destination staff; each handoff needs the right company, terminal and shipment state.
Scoped access
Actions follow company, terminal and role assignments.
Explicit transitions
Each scan checks the package’s current state.
Repeat-safe scans
Repeated scans reuse the recorded transition.
- Book
Register packages
- Pay
Record settlement
- Load
Assign and scan onto trip
- Receive
Confirm arrival
- Release
Prepare for collection
- Claim
Verify the handover

04 / MY CONTRIBUTION
From decisions to delivery.
I lead the engineering team and serve as the primary developer, combining technical direction with hands-on implementation across the Rails platform and shared Expo application.
Technical leadership
- Guide architecture and implementation priorities across passenger, cargo and administrative workflows.
- Coordinate the team’s work around shared business rules and the needs of each operational role.
Core platform development
- Build the booking, pricing, payment and cargo lifecycle features in the Rails business layer.
- Connect company and terminal permissions with the API and operations console.
Mobile & web delivery
- Develop and integrate passenger booking, QR ticket and cargo-scanning experiences.
- Carry changes across the shared mobile app, passenger web pages and operational tools.
05 / TECHNOLOGY
Tools with a purpose.
Passenger & staff experiences
One Expo application adapts to customer, staff and conductor roles; Rails renders the passenger web experience.
Business rules & operations
The Rails monolith owns booking rules, the JSON API, browser sessions and company-scoped administration.
Data, payments & background work
Persistent records, queued work, real-time events, uploads and payment integrations support daily operations.
06 / RESULTS
What the work made possible.
Public web and mobile delivery
Passengers can access the booking website and the Bus Bay Booking apps listed on the App Store and Google Play.
Auditable cargo progression
The cargo lifecycle records each transition from loading through collection, with checks for the responsible terminal and repeated scans.
Shared operational controls
Passenger tickets, cargo bookings, trip assignments and payment records are managed through the same Rails business layer.
