Manzoma ERP: Offline-First B2B SaaS

Manzoma ERP: Offline-First B2B SaaS & POS

The Challenge: Retail stores were losing significant sales and operational capacity during frequent internet outages because their cloud-only POS systems would completely halt.

The Architecture & Solution: I solo-engineered a hybrid offline-first platform from scratch in just 40 days. I built a local desktop POS utilizing SQLite, paired with a custom Node.js background sync engine. This engine securely buffers local transactions and automatically resolves data conflicts with a cloud PostgreSQL database the exact moment connectivity is restored.

The Impact: The system currently manages an active inventory of 3,000+ SKUs and has successfully processed over 1.5M+ EGP in transaction volume, guaranteeing absolute zero operational downtime for merchants.

Tech Stack: React, Node.js, Prisma ORM, SQLite, PostgreSQL, Linux VPS.
