Arsygas Distribution System

Context

End-to-end gas distribution and ordering system. As Development Head and System Architect, designed the complete flow from producer to client ordering with inventory management.

Problem

Gas ordering and distribution relied on manual workflows. Coordination between producers, distributors, and clients was inefficient. Inventory tracking and reconciliation was error-prone.

Constraints

• Multi-role system (Producer, Distributor, Client)
• PO management with approval workflows
• Inventory flow tracking across supply chain
• Reconciliation between orders and deliveries

Architectural Decisions

Designed role-based workflows for different actors in the supply chain. Implemented PO lifecycle management with status tracking. Built reconciliation engine for order-to-delivery matching.

Added inventory flow tracking to maintain data consistency across the distribution network.

Tech Stack

Flutter (Mobile), Laravel (Backend), Express TypeScript (API), Redis (Cache), PostgreSQL.

Outcome

Replaced manual ordering workflows with digital system. Improved data consistency across supply chain. Reduced reconciliation issues between orders and deliveries.

What I'd Improve Next

Would add demand forecasting capabilities. Consider blockchain for supply chain transparency and traceability.
