Project details

A clean, well-documented API built to power your application not a rushed MVP that falls apart at scale.

I'll design and build your REST API with Node.js and PostgreSQL, including authentication, proper error handling, and documentation so your frontend team (or you) can integrate easily.

What's included:
 • API architecture and endpoint design
 • PostgreSQL database schema and setup
 • JWT authentication (or OAuth if needed)
 • Input validation and error handling
 • API documentation (Swagger/OpenAPI)
 • Deployment to AWS or your preferred host
 • Source code via GitHub

Optional add-ons: rate limiting, caching, third-party integrations, WebSocket support.

My background: Nearly 3 years building backend systems for high-traffic iGaming platforms migrating databases from Couchbase to PostgreSQL, and building APIs that handle real money transactions reliably.

Good fit for: Mobile apps needing a backend, SaaS products, frontend teams who need an API built properly, or replacing a fragile existing backend.

Message me with your requirements and I'll confirm scope and timeline.

About Simon

Simon V.Status: Offline
Full Stack Developer with specialisation in AWS
Guaruja, Brazil - 7:14 am local time
I help businesses design and build cloud infrastructure that scales—without overengineering or runaway costs.

I'm a full-stack developer specializing in AWS and Next.js, with a focus on solution architecture. That means I think beyond just writing code: I design systems that are maintainable, cost-effective, and built for growth.

My background includes backend development, microservices, containerization, and leading technical projects across gaming and web platforms. I've optimized systems under heavy load and mentored engineering teams along the way.

What I typically help with:

* AWS infrastructure design and deployment
* Full-stack development (Next.js, Node.js, TypeScript)
* API design and backend architecture
* Migrating or modernizing existing systems

Currently pursuing AWS Solutions Architect certification to formalize expertise I've been applying in practice.

If you're weighing technical options or need someone who can both architect a solution and build it, let's talk.

Steps for completing your project

After purchasing the project, send requirements so Simon can start the project.

Delivery time starts when Simon receives requirements from you.

Simon works on your project following the steps below.

Revisions may occur after the delivery date.

Review the specifications

I'll review your requirements, clarify the data model, and map out the endpoints. We'll agree on the API structure before I write any code.

Database design and setup

I'll design the PostgreSQL schema, set up migrations, and provision the database on AWS. Foundation in place for building the API.

Review the work, release payment, and leave feedback to Simon.
