Get to Know Me

I'm a Software Developer, currently working as a Senior Developer at Aubay, allocated to Aceve, using .NET and C# as the main technologies.

I have over 7 years of experience developing Web, Mobile and Desktop solutions, working with technologies such as .NET, C#, Flutter, MAUI, Angular, JavaScript, among others.

I enjoy building well-structured software, solving complex problems and constantly learning new tools and technologies.

Outside of code, I'm passionate about technology, travel and languages. I currently live in Lisbon, working on international projects and taking the opportunity to discover new cultures and places around the world.
