Fuse_Hostels

Senior .NET Developer

Fuse Hostels • Teilzeit

Feb 2026 - Present • 9 mos

The goal was to provide a brand new website for a hospitality client, powered by a multi-tenant booking and reservations platform for tour and hostel operators, handling live availability, payments and back-office reporting. Alongside feature delivery I focused heavily on database performance — diagnosing and eliminating Azure SQL bottlenecks through covering-index design, query-plan analysis and hand-tuned stored procedures, substantially cutting DTU load under real production traffic I had built multiple websites for hospitality clients in Vietnam, all requiring similar features.
