Modulith Engineering Vision

Executive Summary

The engineering vision is to build Algosure as an enterprise-grade, domain-driven Spring Boot Modulith that faithfully implements the Blueprint before any microservice extraction is considered.

Why This Exists

Algosure is not generic tender software. It is an AI Digital Procurement Company made of Domains, Practices, Digital Professionals, AIOS, workflows, documents, data, integrations, events, and organizational memory. Engineering must preserve that shape.

Engineering Outcomes

Outcome	Meaning
Domain-aligned backend	Every approved Domain has an explicit module where practical.
Modulith first	The backend is modular before it is distributed.
Controlled dependencies	Module dependencies are visible, intentional, and testable.
Event-driven coordination	Cross-module workflows prefer internal events over direct ownership leakage.
Secure tenant model	Tenant and organization context are first-class engineering constraints.
AIOS governance	Digital Professionals execute work through governed application service boundaries.
Future extraction path	Modules can be extracted later when ownership, scale, and operations justify it.

Engineering Non-Goals

• Creating Java code.
• Creating final APIs.
• Creating final database schemas.
• Selecting deployment infrastructure.
• Extracting microservices before module boundaries are proven.
