What I'm looking for

I'm looking to build scalable, secure systems and integrations where I can improve performance, work closely with product, front-end, and QA teams, and continue growing in .NET architecture and cloud delivery.

I'm building and maintaining corporate .NET and Blazor systems at Lanlink, including the Oportunidade/TicBlazor platform, Senior/Sapiens ERP integrations, BPM workflows, and asynchronous processing.

Previously at ZDZCode, I helped migrate a medical-materials quotation system from ASP.NET 1.1 to .NET 8 and Nuxt 3. I moved complex SQL Server procedures into maintainable APIs, introduced Redis caching, and improved API response times by 20%.

At ITIX, I developed web applications for large corporate clients using Angular, Java, Spring Boot, PostgreSQL, Hibernate, and .NET. I also worked directly with an international client on an energy-service contract broker application in English.

I focus on secure, scalable APIs, clean architecture, system integrations, automated testing, and production performance. I enjoy collaborating with front-end and QA teams, documenting integrations, and helping new team members adopt strong development practices.
