Booking platforms, marketplaces, and multi-tenant SaaS — built and fixed under real growth.
Custom page caching · OpenAI async translation · Queue architecture · Client details confidential
A fast-growing booking platform was slowing to a crawl under real traffic. Availability pages were regenerated on every request, and there was no automated way to keep listing content translated for international guests.
A custom page caching layer for high-traffic booking pages, a queue-based availability sync running every 5 minutes, and an async OpenAI translation pipeline that keeps listing content current across languages without blocking requests.
A marketplace for buying and selling video games · Multi-gateway payments · Client details confidential
A multi-vendor gaming marketplace needed to support simultaneous vendor operations, flexible permissions per vendor role, and payments that could fail gracefully across multiple gateways without losing a sale.
A flexible role-permission system for vendors and admins, a multi-gateway payment architecture spanning Stripe, PayPal, and manual settlement, and a vendor backend built to handle simultaneous listings, orders, and payouts without contention.
Multi-tenant from scratch · Three-role permission system · Client: Mitsualti Pidou
A property management SaaS needed to be built from the ground up — clean data isolation between organisations, and a permission structure that matched how property teams, landlords, and tenants actually work together.
A full multi-tenant SaaS architecture with strict data isolation per organisation, a three-role permission system, and complete property and tenant management workflows — from listings through lease management to maintenance requests.
