Commercial web platforms and distributed backend systems.

We design and build customer-facing web applications, B2B and retail e-commerce engines, operational portals, and distributed backend services—engineered for fast response times, strict financial and inventory accuracy, and seamless scaling.

Atomic stock reservation

Single-roundtrip atomic operations prevent concurrent orders from claiming the same unit.

Growing commercial platforms fail when peak traffic causes checkout race conditions, slow catalogue queries, or out-of-sync branch data. We design the data model, caching layers, and concurrency rules upfront so the platform stays fast and accurate as transaction volume grows.

Order routingSimulated

Multi-warehouse inventory routing

Orders allocate stock atomically across regional fulfilment centres based on proximity, availability, and split-shipment rules without database lock contention.

Price listsSimulated

Contract & volume pricing engines

Account-specific price lists, tiered volume discounts, multi-currency ledgers, and credit ceilings are evaluated in memory on every request.

Role maskSimulated

Bitmask role & authority policies

Operational permissions—from purchasing and approval workflows to financial exports—are enforced via 64-bit bitwise masks with zero query overhead.

Branch linkSimulated

Fault-tolerant branch replication

Regional depots and branch offices queue transactions locally during wide-area link outages and reconcile state automatically upon reconnection.
