I will build a scalable rest API using nodejs nestjs and postgresql


About this gig
The backend is the brain of your application. Don't trust it to beginners.
Hi, I'm Sabur Islam Limon, a Backend Engineer with 1.5+ years of real-world production experience. While others write messy code that breaks under pressure, I build secure, scalable, and high-performance backend systems using Node.js, NestJS, and PostgreSQL.
I have maintained live systems, including a Government POS System and EdTech platforms serving real users. I bring that same enterprise-level reliability to your project.
What I will do for you:
- Build robust and secure REST APIs from scratch (Node.js, Express, NestJS).
- Design scalable PostgreSQL/MySQL database schemas.
- Implement secure Authentication (JWT, OAuth, Role-Based Access Control).
- Integrate Third-Party APIs (Stripe, Payment Gateways, SaaS tools).
- Write clean, modular, and well-documented code.
- Provide Swagger/Postman API documentation.
My Tech Stack:
- Runtime: Node.js
- Frameworks: NestJS, Express.js
- Databases: PostgreSQL, MySQL, Prisma, TypeORM
- Auth: JWT, Passport, OAuth2
- Tools: Git, Docker, CI/CD pipelines
Why choose me?
- 1.5+ years of real production experience (not just tutorials).
- I write clean, maintainable code that other developers can easi

FAQ
Do you only use Express, or can you use NestJS too?
I am an expert in both. NestJS is great for large, scalable applications, while Express is better for lightweight APIs. I can use whichever fits your project best.
Will you provide the database schema design?
Yes! For the Standard and Premium packages, I will design the relational database (PostgreSQL) schema and provide it to you before we start coding.
Do you fix existing bugs in Node.js applications?
Absolutely. If you already have a backend that is running slow, crashing, or has bugs, I can step in, optimize the database queries, and fix the issues. Please message me with your bug details.
Will I own the code?
100%. Once the project is completed and payment is cleared, all the source code and database rights belong entirely to you.
