Antwerp Stays

Replaced manual, paper-based workflows for a major Antwerp hospitality operator with a tailored web app suite—live dashboards by role and an offline-first PWA for teams on the move. The platform streamlines 700+ weekly bookings and reduced errors by 75%.

Dualhook

Architected a privacy-first middleware for the Meta Cloud API with a 'Zero-Retention' policy. The infrastructure handles high-concurrency webhooks using Next.js 16 and Turso, featuring multi-tenant isolation via Clerk and automated Stripe subscription tiers.
