使用 React、Node.js、Firebase 和 MySQL 构建 Treasury SaaS

Source: Dev.to

Introduction

Hello DEV community,

My name is Hernán Ricardo Ávila Castillo, a senior full‑stack developer with more than 25 years of experience, based in Guatemala. I am completing my degree in Computer Science and Systems Engineering.

My current focus is the development of a Treasury Management SaaS platform—a modern system designed to support real‑world financial operations, payment workflows, balances, and business controls.

Platform Overview

The platform is being designed to support:

• Treasury operations
• Cash‑flow monitoring
• Accounts payable and receivable
• Payment approval workflows
• Financial tracking across projects and organizations
• A scalable SaaS foundation for future ERP modules

This is not a demo project; the goal is to evolve it into a production‑grade enterprise platform.

Technology Stack

React (Frontend)

React provides an excellent foundation for:

• Admin dashboards
• Component‑driven interfaces
• Long‑term scalability in UI development

Node.js (Backend)

Node.js enables:

• Fast API development
• Strong integration capabilities
• Clean service‑oriented architecture

Firebase (Authentication & Platform Services)

Firebase is used for:

• Secure authentication
• Notifications
• Real‑time capabilities when needed
• Simplified scalability for SaaS workflows

MySQL (Core Financial Database)

MySQL remains a strong choice for treasury data because it provides:

• Relational consistency
• Transactional reliability
• Strong reporting and structured modeling

High‑Level Architecture

        |                   |
 Notifications        Treasury Ledger + ERP Data

This separation allows:

• Clear API boundaries
• Enterprise‑grade data integrity
• Independent scaling of modules

Key Design Principles

After more than two decades building software, several principles remain constant:

• Treasury platforms must be auditable, traceable, and transaction‑safe.

• Data integrity is not optional.

• Every module must evolve independently:

  • Payments
  • Clients
  • Projects
  • Approvals
  • Reporting

Automation and Future Roadmap

The platform is being developed with automation in mind, integrating AI‑driven workflows using tools such as n8n and Make.

Upcoming milestones include:

• Multi‑tenant SaaS structure
• Role‑based access control
• Payment gateway integrations
• Approval pipelines
• Financial reporting dashboards
• Cloud‑native deployment workflows

Why I’m Sharing This

I am joining DEV.to to:

• Share real‑world software engineering experience
• Learn from the community
• Document the evolution of this treasury platform
• Connect with others building fintech and enterprise systems

Final Thoughts

Even after decades in software, building systems like this remains exciting. Technology evolves constantly, and so do we as engineers.

If you are working on treasury platforms, ERP systems, fintech SaaS products, or React/Node architectures, I would be glad to connect and exchange ideas.

Thank you for reading.
