I will develop nodejs nestjs expressjs backend API with graphql postgresql mysql

I mainly work with NodeJS, NestJS, ExpressJS, GraphQL, TypeScript, PostgreSQL, and MySQL. Depending on your project, I pick the best combo—for example, NestJS + GraphQL + PostgreSQL for scalable apps, or ExpressJS + MySQL for quicker builds.

Absolutely! I’m comfortable with both. REST API with ExpressJS is great for simple projects, while GraphQL API with NestJS gives your frontend more flexibility and fewer requests.

Yes, I do full PostgreSQL or MySQL database design—schemas, relations, indexes, migrations, and optimized queries—so your NodeJS backend runs fast and reliably.

Security is a priority. I always add JWT authentication, role-based access, input validation, rate limiting, and follow best practices to keep your NodeJS backend safe.

Definitely. I’ve integrated payment gateways (Stripe, PayPal), auth providers (Google, OAuth), cloud storage, email services, and more into NestJS and ExpressJS backends.

I prefer TypeScript (especially with NestJS) because it catches bugs early and makes the code easier to maintain. But if you need plain JavaScript, that’s no problem.

I design with growth in mind—modular code, proper caching, efficient database queries, and optional Docker setup so your NodeJS backend can handle more users without issues.

Both! I’m happy to build a new NodeJS backend from scratch or jump into your existing NestJS/ExpressJS codebase to fix bugs, add features, or improve performance.

Just a quick description of what you need (features, tech preferences, deadlines). Message me first—I’ll review everything for free and help you choose the right package.

I keep things simple and regular: updates via Fiverr messages, quick explanations of choices, and I’m always available to answer questions so you’re never in the dark.
