Architecture Gallery
System design, at a conceptual level
These diagrams communicate the shape of the systems I build — how requests, data, and permissions flow — without revealing proprietary implementation.
Enterprise SaaS Architecture
The shared shape behind CBSai and its modules: a governed core wrapping independently deployable business domains.
- 1
Client (web)
- 2
API gateway
- 3
Module services (Finance, CRM, HR, ...)
- 4
Shared data layer
Multi-Tenant Architecture
Tenant isolation enforced at the data-access layer so no application-level bug can leak one customer's data into another's.
- 1
Tenant resolver
- 2
Scoped data access layer
- 3
Per-tenant storage boundary
Authentication Flow
Session issuance, token refresh, and identity propagation across services in a multi-tenant system.
- 1
Login / identity provider
- 2
Session issuance
- 3
Token verification per request
Role-Based Permissions
A single permissions model shared by every module and by the AI layer, so access is defined once per tenant.
- 1
Roles & policies
- 2
Permission check middleware
- 3
Module & AI access enforcement
AI Orchestration
Cross-module AI reasoning implemented as orchestration over governed APIs, inheriting existing permission boundaries.
- 1
User query
- 2
Reasoning/orchestration layer
- 3
Governed module APIs
- 4
Grounded response
Voice AI Pipeline
Real-time voice transport decoupled from the reasoning engine so the same intelligence serves chat, voice, and automated briefings.
- 1
Real-time voice transport
- 2
Speech-to-intent
- 3
Reasoning engine
- 4
Voice response
REST API Architecture
Consistent resource modeling, versioning, and permission enforcement across services.
- 1
Resource routes
- 2
Validation & auth middleware
- 3
Service layer
- 4
Data layer
Database Relationships
High-level entity relationships showing tenancy boundaries and shared reference data across modules.
- 1
Tenant
- 2
Core entities (user, account)
- 3
Module-owned entities
Cloud Deployment
Independent scaling per module on cloud-native infrastructure, with CI/CD from commit to production.
- 1
CI/CD pipeline
- 2
Cloud Functions / services
- 3
Cloud storage
- 4
Monitoring & scaling
