About me

I'm a full-stack developer with a back-end focus and a 10th-semester Computer Engineering student at UNIFOR. I have over 2 years of hands-on industry experience building and maintaining web systems, creating RESTful APIs and working closely with clients' business rules.

Most of my experience is on the back end: C# and .NET, from .NET Framework to .NET 8, SQL Server and MySQL, scheduled jobs and tests. Today I also build the front end of the systems I work on with SvelteKit and TypeScript, shipping each feature from the database all the way to the screen.

I enjoy taking legacy code and leaving it better than I found it: refactoring safely, organizing the architecture and making sure the system stays easy to maintain.

APIs and integrations

RESTful APIs in C# and ASP.NET Core that integrate corporate systems and ERPs, with business rules covered by tests.
End-to-end features

From the database to the screen: data model, endpoint, business rules and the SvelteKit interface that uses them.
Legacy modernization

Refactoring architecture and improving legacy code with best practices for maintainability and performance.
Offline-first mobile

An app with Flutter on the front end and C# / .NET on the back end, designed to work without a connection and sync later.

Experience

From legacy to modern: production systems, new APIs and the screens that consume them.
