AppAxioms: The Platform Layer for Production SaaS

Experience, platform, and domain layers of AppAxioms — Figure 1. One product, three layers, many small services—experience, platform, domain.

What AppAxioms is

AppAxioms is Maigha’s shared platform for building and operating production SaaS: authenticated gateways, multi-tenant RBAC, domain microservices, observability, and control tooling— so each venture does not rebuild the spine that every serious product needs.

North star: One product, three layers, many small services. Gateways route. Services own logic. Ventures compound on the same foundation.

Three layers

Layer	Responsibility	Examples
Experience	Portals, landing, UX flows	Web dashboards, marketing site
Platform	Auth, routing, events, observability	FeMux, BeDemux, Redis, messaging
Domain	Bounded business capabilities	Appgen, Mailgen, Logger

Each layer should start, deploy, and fail independently—so a studio can ship ventures without coupling every release to a monolith.

Gateway routing hub distributing to services — Figure 2. FeMux validates and normalizes; BeDemux maps operation + role → service. No business rules in the pipe.

Gateway principle

FeMux — JWT validation, request normalization, WebSocket/SSE, rate limits
BeDemux — route by operation and role; embed or call domain services
Domain services — own data, rules, and side effects for one context only

What ships in the monorepo

Capability	Role
aasctl + Turborepo	Control plane for install, env sync, build, demux merge
Web / portal packages	RBAC dashboards, shared UI, auth client
Appgen	Application generation service and engine
Mailgen	Transactional and platform email
Logger	Centralized logging service
platform-env / service-core	Env profiles, shared middleware, errors, logging factories
Compose infra	Local and platform simulation (Mongo, Redis, RabbitMQ, …)

Multi-tenant RBAC

Roles and permissions are first-class: platform admins, firm-scoped operators, and gated operations through demux config—not ad-hoc checks sprinkled in UI. That is how TaxInsights, MROS, and future ventures inherit a serious tenancy bar instead of inventing one per repo.

Studio leverage: Auth, routing, mail, logging, and ops tooling become platform compound interest—the unfair advantage behind faster, cleaner venture builds.

Why it matters

Stop paying the “rebuild the platform” tax on every product
Keep gateways thin and domain services accountable
Ship with RBAC, observability, and env discipline from day one
Let Maigha ventures share infrastructure without sharing product destiny

Summary

Product: AppAxioms — the platform layer for production SaaS.

Function: Gateway routing, multi-tenant RBAC, domain microservices, shared packages, and aasctl/Turborepo control.

Outcome: Ventures move faster on a spine built for international, production standards.
