01 / Overview
The problem and my contribution.
Mobility services are usually split across maps, calls, store visits, and disconnected booking tools. The product needed one discovery and operations layer without losing ownership boundaries.
My roleProduct design and full-stack development
OwnershipIndividual project
I designed and implemented the customer experience, business onboarding, owner operations, administration, reservations, store checkout, data model, security controls, and automated verification.
02 / Architecture
How the product is put together.
API
Validated and rate-limited mutations
Domain
Role and ownership rules
Database
Prisma transactions on MySQL
Technology choices
Next.js + React
Server rendering and interactive portals in one product.
TypeScript
Shared types reduce mistakes across forms, APIs, and dashboards.
MySQL + Prisma
Relational ownership, reservations, inventory, audit logs, and transactions.
JWT session cookie
Short-lived role-bearing session stored in an HttpOnly cookie.
03 / Engineering
Challenges and decisions.
The API evaluates branch hours in the station timezone and blocks active reservations inside the conflict window.
Checkout decrements stock conditionally inside one transaction, so concurrent orders cannot silently oversell.
Owner mutations query by both resource ID and authenticated owner ID; admin and customer routes require exact roles.
04 / Product

Dockerone-command stack
- CI runs the security tests and a production Next.js build.
- Docker Compose starts MySQL, applies the Prisma schema, seeds demo users, and launches the app.
- Security tests inspect password hashing, cookie flags, ownership scopes, booking conflicts, and inventory transactions.
