I'm Pedro Miguel Aquino Costa Gomes, a Full Stack Developer based in Recife, Brazil 🇧🇷.
Graduated in Systems Analysis and Development (SENAI-PE), currently pursuing a Bachelor's degree in the same field, I specialize in building SaaS platforms with AI, scalable back-end systems, and cross-platform mobile applications.
I work across the full lifecycle: from designing multi-tenant architectures with PostgreSQL (RLS) and Redis, to building AI-powered pipelines with Claude, GPT-4o, and Gemini (RAG, lead scoring, NLP), to deploying on Docker, Nginx/PM2, Vercel, and Linux/VPS environments.
What I bring to the table:
- ✅ SaaS multi-tenant platforms with RBAC, JWT, and LGPD compliance
- ✅ AI integrations (Claude, GPT-4o, Gemini, RAG with pgvector, NLP)
- ✅ Full-stack e-commerce with Stripe & Mercado Pago (PIX, card tokenization)
- ✅ WhatsApp bots & automation (Baileys, 40+ commands, lead capture)
- ✅ Mobile development with Flutter + Firebase (real-time sync, offline support)
- ✅ DevOps: Docker, GitHub Actions CI/CD, Nginx, PM2, VPS provisioning

I build AI-first SaaS platforms with RAG pipelines (pgvector embeddings), multi-provider LLM orchestration (Claude → GPT-4o → Gemini with automatic fallback), real-time WebSocket communication, and intelligent WhatsApp bots for lead capture, customer support, and financial management.
