About Maria

I am a developer with several years of experience working with Java, JavaScript, React, and other frontend and backend technologies. I have worked on new projects from scratch and also on quite complex legacy applications, so I am used to both building and maintaining and improving existing systems.

I can take on a complete project, from the initial idea to production:

If you need something simple, fast, and modern, we can set up a frontend with React + Vite and a REST API with Node.js.
If you are looking for something more prepared to grow and scale, we can work with React + TypeScript on the frontend and microservices in Java or Go, applying clean architecture and best practices from the beginning.

I have experience in solving bugs, improving performance, creating tests, integrating APIs, and quickly adapting to different technologies or projects. I work with agile methodologies like Scrum and have participated in evolutions, e2e tests, regression, and maintenance of enterprise applications.

Furthermore, outside of work, I continue to learn and create personal projects related to clean architecture, microservices, and modern development because I genuinely enjoy programming and continuous improvement.

I like to do things well and maintain clear communication throughout the project. If there is a technology I don't know yet, learning it will not be a problem. I am motivated by technical challenges and projects where I can truly contribute.
