Freelancer profile translated to English.

Description

Hello and welcome to my profile!

Senior Full Stack Developer with over 8 years of experience, I assist companies and public institutions in the design, development, and modernization of robust and scalable critical applications.

My expertise primarily revolves around the .NET ecosystem (C#) for the backend and React.js / TypeScript for the frontend, with a strong focus on code quality (SOLID, Clean Code, TDD).

🛠️ My areas of intervention:

Architecture & Backend: Design of microservices architectures, implementation of CQRS patterns (MediatR), exposure of REST APIs (Ocelot), and integration of asynchronous messaging (RabbitMQ).

Frontend & Mobile Development: Creation of dynamic and performant web interfaces with React, and management of mobile transitions (such as migrating from Flutter to React Native).

DevOps & Cloud: Setup and management of automated CI/CD pipelines with Azure DevOps, containerization with Docker, and management of Cloud services (Firebase Cloud Messaging, Keycloak OIDC/OAuth2).

Why work together?

Accustomed to demanding contexts (public sector, large consulting firms like Accenture) and Agile methodologies (Scrum), I quickly integrate into your remote teams. Beyond development, I bring real added value on architectural choices, application security, and the sharing of best practices (code reviews, mentoring).

Let's discuss your needs and how I can propel your projects!
