João Vitor Retamero

I’m a Senior .NET Software Engineer with 12+ years of experience building enterprise applications, REST APIs, web dashboards. I focus on reliable, scalable systems and enjoy translating requirements into maintainable solutions using C# and the .NET ecosystem.

In my current role at Gera Sales Ecosystem, I maintain and evolve a direct sales management platform operating in 5 countries, improving reliability and scalability. I provide technical direction and code/design reviews, support functional analysts with technical assessments, and participate in architecture discussions and implementation planning—working closely with clients like Natura, Avon, Jequiti, Tupperware, and Bagués.

Previously, I built web dashboards and automated issuing of freight fiscal documents at FR Consultoria & Inovação, and I enhanced and supported a management system at GAtec Gestão Agroindustrial. Earlier, at HPro, I analyzed and developed customized ERP systems and led deployments after gathering requirements; beyond that, my Hermes project delivers end-to-end automation with Android (Kotlin), Node.js, C#, and SQL Server. I bring strong SQL/data modeling, troubleshooting, and technical leadership, backed by Microsoft certifications (MCSA: Web Applications and MCSD: App Builder).
