At Grupo Report, I took the Materiality System from MVP to a secure, production-grade ESG SaaS that replaced spreadsheets and manual workflows. It now serves 22 companies, including Caixa, Unimed and Beneficencia Portuguesa.
I also maintain and extend two corporate CRMs on AWS, integrated with Omie and TeamGantt. I optimized AWS RDS queries for a critical page, reducing load time from about seven seconds to 0.3 seconds.
For the Materiality System, I integrated an MCP server to connect the platform with AI assistants and automated CI/CD pipelines for weekly releases. I work across Node.js, TypeScript, PostgreSQL and AWS, and am implementing RabbitMQ messaging between services.
As a freelance web developer, I helped found MindLaw, a law-firm management system that retrieves court cases and integrates with Claude via MCP; it serves about 100 law firms and 5,000+ app users. I also delivered around 50 websites, e-commerce stores and custom web apps, and reviewed web development lessons and projects at Trybe.
