Continuous Operations

Your business keeps running even during connectivity outages. Warehouses, field devices, and branch offices continue billing and recording data locally without interruption.

Data Sovereignty

Leverage dedicated, self-hosted infrastructure to eliminate recurring API fees (such as map requests) while retaining complete ownership over confidential records.

End-to-End Integration

Guaranteed architectural cohesion across every layer: bare-metal server provisioning, embedded edge nodes, synchronization engines, backend APIs, and native mobile apps.

Technical Capabilities

High-Performance Technical Solutions

Bespoke software development and infrastructure deployment engineered for 24/7 uptime and absolute data sovereignty.

Multi-Site Synchronization & Offline-First

Bidirectional data systems with local persistence ensuring continuous uptime without active connections, powered by deterministic sync and automated conflict resolution.

PRODUCTION CASE STUDY·PROJECT SaSa

Dynamic Pricing, Routing & Telemetry Platform for VTC Fleets

Comprehensive platform architecture enabling customers and dispatchers to book and manage private chauffeured services via mobile apps and a web dashboard. The core backend processes route calculations, transit time estimations, road distance metrics, and accurate pricing via dynamic fare calculation matrices.

Autonomous Routing

Point-to-point pathfinding and distance matrices computed locally without recurring third-party API dependencies or fees.

App ↔ Backend Synchronization

Real-time bidirectional event streaming for job dispatch, driver assignments, and custom tiered fare calculation.

SaSa Technical Specifications
