Do you need a robust web application, a scalable API, or want to bring that product idea you've been postponing to life? I can help you build it from start to finish, with a special focus on backend and real-time architectures.

I am a Full Stack developer specializing in Node.js, NestJS, React, and Next.js, with a background in Web Application Development (Honors) and practical experience in production projects, both in companies and personal projects.

How can I help you?

- Development of scalable and well-documented REST APIs (Node.js, NestJS, Swagger)

- Full stack web applications with Next.js/React on the frontend and modern architectures on the backend

- Real-time systems: chats, live notifications, dashboards with WebSockets/Socket.io

- Queue management and asynchronous processes (BullMQ + Redis) for background tasks

- Relational databases (PostgreSQL, MySQL) with Prisma or TypeORM

- Containerization and deployment with Docker

What sets me apart

I'm not a "generic" full-stack: I have a clear focus on a solid backend, which means the apps I build not only look good, but are designed to scale and be maintained over time. I've developed UmbraChat from scratch, a real-time chat app (Next.js + WebSockets + Prisma/PostgreSQL), and Referigo, a full stack application deployed in production with Angular, NestJS, MySQL, and a Redis queue system.

Types of projects I usually manage

MVPs for startups, APIs for connecting services or mobile apps, migrations and improvements of existing applications, integration of real-time functionalities, and AI automations to optimize processes.

I work with agile methodology, clear communication, and incremental deliveries, so you always know the status of your project. If you're looking for someone who gets involved in the product as if it were their own, let's talk.
