🧾 Case Study: ERP System Architecture

Sector: Business Management Software
Role: Lead System Architect
Client Impact: Unified ERP deployments across industries with tailored workflows and extensibility


🎯 Objective

To design a multi-industry ERP platform that could scale with businesses and adapt to their unique internal processes.


⚠️ Challenge

ERP adoption was blocked by:

  • One-size-fits-all limitations from existing platforms
  • Inflexible database schemas
  • Lack of modularity in key business logic (Purchasing, HR, Projects)

🧩 Solution

I took ownership of the ERP system's data and software architecture, focusing on adaptability, clean integrations, and scalability.

Key Contributions:

  • Module Architecture: Designed Purchasing, Project Management, and Operations as flexible, standalone components.
  • Client-Centric Modeling: Translated real-world workflows into scalable backend data structures.
  • API & Integration Layer: Engineered backend logic and APIs with mobile support and cross-module communication in mind.

📊 Impact

  • 🔄 Deployed across multiple industries without core code rewrites
  • 🧱 Architectural flexibility led to seamless adoption and integration
  • ⚙️ Backend scalability ensured long-term maintainability and extensibility

🧪 Technical Stack

Layer Technology Used
Backend C, QCGI
Frontend JavaScript, QCGI.js, Chart.js
Communication Unix Domain Sockets, TCP/UDP, WebSockets
Environment Linux, CRON, VIM, SSH

💡 Key Takeaway

True ERP flexibility comes not from "no code" gimmicks—but from a strong architectural foundation that respects how real businesses operate.
