Mig Mig Gastro
High-availability, fully localized end-to-end production platform for a Swiss restaurant group. Sustains 5,000 concurrent sessions with page loads under 900ms.
The Problem
A monolithic stack buckled under peak lunch-hour traffic — page loads exceeding 8 seconds drove cart abandonment to 42%, bleeding revenue during the highest-demand windows across Swiss national holidays.
System Architecture
Deployed a Next.js 15 headless frontend with Redis-powered caching grids and a Go-based ordering API architected for sustained 5,000 concurrent sessions. Localized checkout flows and compliance logic embedded at the transport layer.

Technical Challenges & Trade-offs
Maintaining zero-downtime deployments through peak traffic surges (Swiss holidays) while migrating a live monolith. Enforced strict cache-invalidation discipline across the Redis grid to prevent stale pricing during flash demand spikes.
Business Impact & Metrics
Page loads dropped to under 900ms. Cart completion rate rose from 58% to 78%. Platform scaled zero-downtime through Swiss national holidays — converting a failing monolith into a revenue-generating asset.
