AI-native Senior Full Stack Engineer
Agentic AI is part of how I build, not a line I added to my profile. Claude Code runs in my daily development, and I wrote an open source multi-agent orchestration plugin for it that splits a plan across parallel isolated agents with an automated review gate before anything merges. On the client side, Gemini, Vertex AI and Cloud Text-to-Speech are things I've shipped into production features, not demos. I'm also midway through a postgraduate program in software engineering with applied AI.
That only matters because the engineering underneath holds up. Earlier this year I put seven full stack systems into production in five months at an AI consultancy. One was a healthcare platform with legally binding digital signatures (ICP-Brasil via VIDaaS) and integration with Receita Saúde, the Brazilian tax authority's health reporting system. The others covered agrotech, public procurement, B2B SaaS and AI audio/image generation. NestJS, TypeORM and PostgreSQL on the back, React 18/19 with Vite and TanStack Query on the front, some of it offline-first PWA.
Today I run two client contracts in parallel through my own consulting company. One is a financial market software house, where I work in Java with Spring plus TypeScript on both sides. The other is a tech company where I build in TypeScript with services in Go and Python, and own the infrastructure in Terraform (CDN, WAF, APIs) from provisioning through deploy.
Before that I spent close to two years on Node.js microservices in a B2B SaaS platform for internet providers. The piece I'm proudest of there is a WhatsApp billing automation serving thousands of subscribers: recurring charges, retries and notifications, running in production with real money attached.
I'm open to contract work and to full-time remote roles. English is C1, and I'm based in Brazil (GMT-3), so I overlap with most of the US day and part of the European afternoon.
