At AMVOX, I developed and maintained complex web interfaces with React.js and TypeScript, and led the migration of a legacy codebase from React 17 to React 19, improving load time by up to 60%. I also implemented REST APIs with C# and ASP.NET Core.

I customized TOTVS Protheus with ADVPL, TLPP, Angular, and PO-UI, and created interactive dashboards that brought real-time sales and production KPIs together for executive decision-making.

I built DevRadar, a real-time platform for collecting and curating tech job listings, with NestJS, TypeScript, and PostgreSQL. It includes more than 1,000 automated tests with over 95% coverage, plus a CI/CD pipeline and automated deployment.
