I will develop a secure architecture backend API with custom node
Jorge G.
Sobre este Serviço
Stop deploying vulnerable backends.
Your business deserves enterprise-grade data security.
Whether building a healthcare platform, SaaS, or internal portal, I engineer secure REST APIs using Node.js, Express, and MongoDB Atlas. With 5+ years of experience, I protect your assets from day one.
AUDIENCE BENEFITS & BUSINESS VALUE: Data Privacy: Protect sensitive compliance data with enterprise-grade encryption. Automated Deploy: Zero DevOps stress with GitHub Actions CI/CD pipeline directly to Railway. High Performance: Optimized database pooling built to handle massive concurrent traffic.
️ METADATA SECURITY HARDENING: Node.js & Express: Advanced JWT Role-Based Access Control and strict input sanitization. NoSQLi & ReDoS Mitigation: Query type-checking to completely block injection payloads. Privilege Escalation Guard: Field whitelisting isolates role modifications to admins. Cryptographic Sovereignty: Ephemeral TLS_CERT_B64 usage to leak zero keys on disk. Secure HTTP Headers: Hardened Helmet policies blocking cross-site scripting vulnerabilities.
Message me before ordering to discuss your backend architecture!

Perguntas frequentes
Do you follow standard API naming conventions?
Yes, absolutely. All routes are normalized and written strictly (e.g., /api/v1/doctors, /api/v1/hospitals) utilizing correct HTTP verbs (GET, POST, PUT, DELETE) and returning perfectly structured plural JSON arrays.
How do you guarantee database security on cloud environments?
I enforce zero hardcoded keys by utilizing environment variables. Additionally, for modern ephemeral hosting like Railway or automated CI environments, I implement TLS_CERT_B64 to handle database TLS certificates safely in-memory without persistent disk footprints.
Is the backend protected against modern database attacks?
Yes. The application layers include active NoSQL injection filters on query parameters, input type-checking on logins, and sanitized regex inputs to completely neutralize Regular Expression Denial of Service (ReDoS) threats.
What package manager and deployment setup do you use?
I use pnpm for ultra-fast, deterministic dependency management with a strict lockfile. For deployment, I provide a native GitHub Actions workflow alongside a tailored railway.json file configuring automatic restarts and automated health check paths.
Is this Node.js backend compatible with my existing frontend technology?
Yes, 100%. The backend is a decoupled REST API using JSON, making it fully compatible with any frontend like Angular, React, Vue, Next.js, or mobile apps. I also pre-configure secure CORS policies to ensure seamless, safe, and immediate integration with your domain.
