I will build a scalable saas backend or secure rest API with nestjs
Benjamín Corona
About this gig
Are you looking for a bulletproof, enterprise-grade backend that won't break when your user base grows? You are in the right place.
Many developers build APIs that work for a few users but crumble under heavy traffic due to poor architecture. As a Software Engineer, I specialize in building highly structured, clean, and scalable backends using NestJS and TypeScript.
Whether you are launching a new SaaS MVP, need a secure engine for your mobile application, or want to migrate a legacy system, I will write clean, modular code following industry best practices.
️ What I bring to your project:
- Strict separation of concerns (Modules, Controllers, Services).
- Robust integrations with PostgreSQL, MySQL, or MongoDB using Prisma or TypeORM.
- JWT Auth, Bcrypt password hashing, and Role-Based Access Control (RBAC).
- Efficient database queries and DTO validation.
- Interactive Swagger/OpenAPI docs so your frontend team can integrate seamlessly.
- Dockerized setups for smooth deployments.
Note: Every project has unique technical needs. Please send me a message before placing an order to discuss your architecture and requirements. Let's build a rock-solid foundation for your software!

I specialize in building scalable, high-performance applications within the modern TypeScript ecosystem. I craft lightning-fast frontends using Astro and React, and engineer bulletproof backends with NestJS, Node.js, and Docker.
My background includes engineering roles at the Scripps Research Institute and serving as a Senior Developer. I’m also an active open-source NPM contributor.

FAQ
Do you build the Frontend as well?
Yes! While this gig is strictly focused on robust NestJS backend architecture, I am also a Senior Frontend Developer. If you need a full-stack solution (like connecting this API to a React or Astro frontend), send me a message and we can create a custom offer.
Which database do you recommend for a new SaaS?
I highly recommend PostgreSQL combined with Prisma ORM. It provides an excellent balance of relational data integrity, scalability, and type safety. However, I am fully equipped to work with MySQL or MongoDB if your architecture requires it.
Will you deploy the API to a server?
I deliver production-ready code, typically including a Dockerfile for easy deployment. If you need me to personally configure your VPS, AWS, DigitalOcean, or Railway account to deploy the backend, please let me know and we can add it as an extra service.
