Backend-focused Fullstack Engineer
Multi-tenant SaaS · LLMs in production · Django · FastAPI · Next.js
Backend-focused fullstack engineer at Carvion, where I build Orquestra360: a modular, multi-tenant SaaS platform whose products (under the Bravend brand) share a single auth, billing and tenancy core. I'm strongest on the server side: REST APIs, schema-per-tenant data isolation, async pipelines and LLMs in production. I build the React frontend too.
- 🏗️ Backend & architecture: Django/DRF and FastAPI, schema-per-tenant multi-tenancy, SSO with JWT RS256, credit/billing engines
- 🗄️ Data & async: PostgreSQL data modeling, Redis, Celery task pipelines, object storage (S3/MinIO/R2)
- 🤖 Applied AI: OpenAI and Anthropic in production (hybrid AI scoring, Whisper voice, automated report generation)
- 🐧 Systems: at home on Linux (Fedora on desktop, Linux servers in production), Docker and CI/CD on GitHub Actions
- 🎨 Frontend: Next.js, React and Radix/shadcn design systems

Orquestra360 is the hub: most of these plug into its SSO, credit wallet and internal APIs. A couple stand on their own.
| Project | What it is | Stack |
|---|---|---|
| Orquestra360 | Hub platform: SSO (JWT RS256), schema-per-tenant multi-tenancy, white-label, cross-module credit wallet | Django Next.js PostgreSQL Redis |
| Siv360 | AI sales simulator with hybrid AI + human scoring (GPT-4o-mini) and live voice input via Whisper | Django OpenAI Celery |
| Assessments360 | 360° assessments, DISC, PDI and career/competency management | Django Next.js Recharts |
| Learning360 | Gamified LMS: learning paths, courses, certificates and forums | Django Next.js Tailwind |
| Fala T&D | Offline-first live-audience PWA: QR check-in, ICP scoring, CRM webhooks | FastAPI Next.js IndexedDB |
| Vinvolve | Standalone course and membership hub with auth and transactional email, outside the 360 stack | React Vite Express Drizzle |
Also LAB.AIx: an AI kiosk that turns a recorded voice diagnosis into an ADDIE learning blueprint with Whisper and Claude Sonnet.
12k+ contributions in the last year, most of them in private repositories.
Versão em português
Engenheiro fullstack com foco em backend na Carvion, onde construo o Orquestra360: uma plataforma SaaS multi-tenant e modular cujos produtos (sob a marca Bravend) compartilham um núcleo único de autenticação, cobrança e tenancy. Sou mais forte no lado do servidor: APIs REST, isolamento de dados schema-per-tenant, pipelines assíncronos e IA em produção. Também faço o frontend em React.
- 🏗️ Backend e arquitetura: Django/DRF e FastAPI, multi-tenancy schema-per-tenant, SSO com JWT RS256, motores de créditos e cobrança
- 🗄️ Dados e async: modelagem em PostgreSQL, Redis, filas com Celery, object storage (S3/MinIO/R2)
- 🤖 IA aplicada: OpenAI e Anthropic em produção (scoring híbrido, voz com Whisper, geração automática de relatórios)
- 🐧 Sistemas: Linux no dia a dia (Fedora no desktop, servidores Linux em produção), Docker e CI/CD no GitHub Actions
- 🎨 Frontend: Next.js, React e design systems com Radix/shadcn
