About
I'm a full-stack software engineer with a fintech focus, building high-performance backend systems with TypeScript, Bun, Elysia.js, and Next.js. I specialize in payment integrations (PIX, Stripe), WhatsApp Business API automation, AI-powered workflows, and API architecture for credit and financial products.
Currently working as Senior Software Engineer at Engrenna, a Brazilian vehicle credit fintech, co-leading a migration from a legacy .NET stack to a modern Bun/Elysia/Next.js architecture — and integrating AI directly into credit validation workflows using the Anthropic Claude API.
I also build on the side: AutoZappr, a WhatsApp automation SaaS.
Outside work, I play piano, do Taekwondo, and speedcube. Dark mode is still a lifestyle.
