About

GAUSS Platform is a modular financial platform under active development, designed to support banks, fintechs, credit institutions, finance companies, direct credit companies (SCD), and other financial market participants.

The platform is being built as a multi-tenant SaaS with a strong focus on security, tenant isolation, auditability, regulatory readiness, and modern cloud-native engineering practices.

GAUSS Platform aims to modernize legacy credit and banking management systems by combining modular architecture, automated credit workflows, configurable business rules, identity management, observability, and compliance-oriented foundations.

Key Differentiators

Feature	Description
Multi-tenant SaaS	Designed for strong tenant isolation across data, identity, configuration, audit, and operational boundaries.
Modular Architecture	Business capabilities are organized as independent modules and bounded contexts, allowing gradual evolution and selective adoption.
Security by Design	Authentication, authorization, password hashing, token-based access, validation pipelines, and auditability are treated as core platform concerns.
Regulatory Readiness	Designed with Brazilian financial market requirements in mind, including LGPD, BACEN-oriented controls, audit trails, and future support for regulatory reporting.
Credit Platform Foundation	Planned support for credit product configuration, client registration, simulation, approval workflows, negotiation pipelines, and digital formalization.
White-label Ready	Planned tenant-level branding, custom domains, onboarding configuration, and institution-specific settings.

Current Status

GAUSS Platform is currently in the initial foundation phase.

The current development focus includes:

• Modular monolith solution structure
• Application building blocks
• Identity domain model
• User registration
• Login with access token
• API validation pipeline
• SQL Server persistence
• FluentMigrator database migrations
• Unit, integration, and API tests
• Azure Pipelines CI for build and automated tests

---

Architecture Principles

The platform follows engineering practices commonly used in enterprise and financial systems:

• Domain-Driven Design
• Clean Architecture
• Modular Monolith
• CQRS-oriented application use cases
• Explicit application contracts
• Result-based error handling
• Minimal APIs
• Validation pipeline
• Automated tests
• CI pipeline with build, unit tests, integration tests, and API tests
