I will build a secure rest api using node js express js mongodb postgresql and prisma
Rony Islam
About this gig
Stop building unscalable backends.
Modern applications require speed, security, and scalability. Whether you need the strict structure of SQL or the flexibility of NoSQL, I specialize in building type-safe, high-performance REST APIs using Node.js and TypeScript.
Which Database do you need?
I am an expert in both modern stacks:
- PostgreSQL + Prisma: Perfect for SaaS, E-commerce, and Finance apps where data relationships (SQL) are critical.
- MongoDB + Mongoose: Best for Social Media, Content Platforms, and Big Data apps requiring flexibility and speed.
My Tech Stack:
- Runtime: Node.js & Express.js
- Language: TypeScript
- Database: PostgreSQL OR MongoDB
- ORM/ODM: Prisma OR Mongoose
What is Included?
- Swagger API Documentation (So your frontend team knows how to use it).
- Advanced Validation (Zod for Prisma / Joi for Mongoose).
- Secure Authentication (JWT, Bcrypt, Refresh Tokens).
- Complex Queries (Mongoose Aggregations or Prisma Relations).
Why choose me?
I don't just write code; I design architectures. I ensure your backend is secure, optimized, and ready to scale from Day 1.
Send me your project requirements, and let's choose the best database for your app!

FAQ
Q: Do you provide API documentation for the frontend team?
Ans: Yes! I provide complete Swagger (OpenAPI) documentation. This allows your frontend developers to test endpoints interactively and understand exactly what data is required without needing to read the code.
Q: How do you ensure the API is secure?
Ans: Security is my priority. I implement JWT Authentication for secure login, Bcrypt for password hashing, Helmet.js for HTTP header protection, and Zod/Joi validation to prevent bad data or SQL injection attacks.
Q: Can you use MongoDB/Mongoose instead of PostgreSQL?
Ans: Yes, absolutely. While this gig highlights PostgreSQL/Prisma for relational data, I am also an expert in MongoDB and Mongoose. If your project requires a NoSQL structure, just let me know!
Q: Will the code be scalable for a startup?
Ans: Yes. I write clean, modular code using TypeScript and the MVC Architecture (Model-View-Controller). This means as your user base grows, we can easily add new features without breaking existing ones.
Q: Do I own the source code?
Ans: Yes, 100%. Once the order is complete, you own the full source code and intellectual property. I will deliver it via a GitHub repository or a Zip file.
