E-motion

Context

E-motion runs racing simulator centres and needed to move bookings, session packs, and subscriptions off spreadsheets and phone calls onto a self-service platform its customers could use from a phone.

The challenge

Simulator slots are a scarce resource: two people must never end up on the same rig at the same time, and pack credits have to stay consistent even when a booking is cancelled or moved. The booking flow also had to stay fast on mobile, where most sessions are actually reserved.

What I built

• Built the customer-facing booking journey in Next.js and React with TypeScript end to end, from slot selection through to confirmation.
• Designed the NestJS API around sessions, packs, and subscriptions, keeping credit accounting and availability in one authoritative place.
• Modelled availability so concurrent bookings cannot double-allocate the same simulator slot.
• Instrumented the platform with Datadog so booking errors and slow endpoints surface before customers report them.
• Tuned the front end for Core Web Vitals: server rendering, image optimisation, and a booking flow that stays responsive on mobile networks.
