About Me

Full Stack .NET Developer with 6+ years of experience building web applications, REST APIs, frontend SPAs and developer tools. Specialized in Clean Architecture, DDD and the full Microsoft stack — from backend APIs to Angular and Blazor frontends.

Career Overview

I currently work at one of the largest ERP systems in Brazil, developing and maintaining enterprise-level applications used by thousands of businesses. I have extensive experience with REST APIs, SOAP XML, WebHooks, async/await patterns, and working with legacy code.

On the backend, I work daily with .NET (Framework and Core), ASP.NET Core, Entity Framework Core, and multiple databases including SQL Server, PostgreSQL and MongoDB. On the frontend, I build SPAs with Angular and interactive UIs with Blazor, always focusing on clean and maintainable code.

I also have hands-on experience with Brazilian fiscal document processing (NF-e, NFC-e, CT-e, MDF-e, NFS-e, CF-e), digital signatures (A1/A3 certificates) and cloud infrastructure with AWS and Docker.

My focus is on creating maintainable, well-tested and scalable software following Clean Architecture and Domain-Driven Design principles.
