Fullstack developer building the whole product — schema to screen.

Design, build, and sell subscription software end-to-end — from product and schema to deploy and support. My flagship, AlugaFácil, is a multi-tenant rental-management SaaS running in production on a self-hosted VPS with real paying customers, and I keep shipping improvements to it today. Every layer is mine: Next.js + Drizzle on PostgreSQL, Better Auth, Docker, and Cloudflare R2.

Build internal and client-facing products end-to-end at a city-planning and management institute. Shipped 5+ internal systems behind a shared authentication gateway, an education platform for a client, and a Flutter health-monitoring app for elderly care paired with a web panel for health agents. I weigh in on architecture and own features across the stack — Nest + Prisma APIs through Next.js, TanStack and shadcn/ui frontends.

Researcher on LITII4, an Industry 4.0 initiative bridging UFSJ and AMG Brasil S.A. in the metallurgy sector. Built technology to modernize production processes — data analysis to surface operational improvements, plus automation and IoT integration to raise efficiency on the factory floor.

Built a cross-platform app helping small-scale producers digitize zootechnical record-keeping — capturing and tracking animal data that used to live on paper. Shipped with Flutter for multi-platform reach and SQLite for offline-first local storage, collaborating through Git/GitHub.
