Hi, I'm Carlos Díaz

Fullstack Software Engineer → Blockchain | NestJS · GCP · Flutter | Production-ready systems | Open to Remote

About Me

Fullstack developer with 3+ years building production systems across web, mobile, and backend — currently transitioning into Blockchain/Web3 development. I work with NestJS and PostgreSQL on the backend, Flutter with Riverpod on mobile, and React/Next.js on the frontend. I also build AI-powered conversational agents, serverless platforms on GCP, and cross-chain testing infrastructure on top of public blockchain protocols (viem, Anchor SDK, @solana/web3.js), covering 8 active chains (EVM + Solana).

  • 🎓 Computer Engineering · Universidad Rafael Urdaneta, Maracaibo
  • ☁️ Serverless architectures on Google Cloud Platform (Cloud Run, Cloud Build, Secret Manager)
  • 🔗 Web3 / cross-chain infrastructure across EVM + Solana, validated on live mainnet (Eco Routes protocol)
  • 🤖 AI agents & automation with n8n, Claude API and WhatsApp Cloud API
  • 🔗 ERP integration with Odoo via XML-RPC and Google Workspace API (Drive, Sheets, OAuth 2.0)
  • 🔐 Auth systems with JWT rotation, token family tracking, bcrypt and RBAC
  • 🐳 Docker, CI/CD with GitHub Actions / Cloud Build, and production deployments
  • 📱 Mobile development with Flutter + Riverpod and React Native + Expo
  • 🤝 Open to remote opportunities and collaborations
