Zero data loss
A high-scale logistics and synchronisation platform for luggage tracking and field operations. The hardest problem was not throughput — it was integrating with a service provider whose API specification and business rules kept moving. I solved it with a decoupled, highly adaptable synchronisation scheduler that insulated the core system from upstream change, keeping data flowing without a single loss.
