Sobre este Serviço

Looking for a backend that doesn't just work, but scales?

With over 20 years of experience in high-stakes environments and complex system management, I don't just "write code." I build robust, secure, and mission-critical architectures designed to solve real business problems.

Whether you are launching an MVP or scaling an enterprise-grade application, I provide professional backend development focused on performance, clean code, and seamless integrations.

What I can do for you:

  • Custom API Development: RESTful services using Node.js, Python, or Firebase.
  • Database Design: Optimized SQL/NoSQL architectures (PostgreSQL, MongoDB, Firestore).
  • Complex Automations: Advanced workflows using n8n to connect your entire ecosystem.
  • Third-Party Integrations: Payment gateways (Stripe/PayPal), WhatsApp APIs, CRM, and Cloud Services.
  • Cloud & DevOps: Dockerized environments and CI/CD pipelines for automated deployment.

Why choose my service?

  • Strategic Vision: I understand the logic behind the business, ensuring the tech supports your goals.
  • Security First: Implementation of JWT, OAuth, and data protection best practices.
  • Clean & Scalable Code: Easy to maintain and ready for future growth.
