Project details
This service focuses on building backend systems that connect your frontend, databases, and third-party services smoothly. A well-built Node.js backend allows your product to respond quickly, handle user actions properly, and grow feature by feature without breaking existing functionality.
I've built backend systems for products serving millions of users, including Kyan Health — a €17.4M funded platform with 3M+ users across Europe.
After delivery, your application will have a backend that developers understand, clients trust, and users never notice — because it simply works.
This setup is ideal for APIs, web platforms, SaaS products, and applications that rely on real-time interactions.
What's included:
• RESTful API with Node.js / NestJS / Express
• Database design and setup (PostgreSQL, MongoDB, or MySQL)
• Authentication and security (JWT, OAuth, Firebase Auth)
• Third-party API integrations (Stripe, Google, OpenAI, and more)
• Cloud deployment on AWS or GCP
• Clean documentation handed over with every project
