👋 Hi there, I'm Juan

Full Stack & Blockchain Developer | Web3 Builder | Tokenization Enthusiast

🧠 About Me

I'm a full-stack developer with a background in Industrial Engineering and 3+ years of experience building scalable systems across Web2 and Web3. I specialize in backend development with NestJS, microservices, and event-driven architectures, and I’m passionate about creating seamless developer and user experiences on the blockchain.

I transitioned into tech from a background in IoT and sales, and since then, I’ve worked on innovative solutions involving tokenized assets, cross-chain interoperability, and developer tooling. I've contributed to multiple open-source projects, participated in and won Web3 hackathons, and built systems deployed on AWS (ECS + RDS) using modern DevOps workflows.

🚀 What I'm working with:

  • Backend: NestJS · RabbitMQ · PostgreSQL · GraphQL · Microservices · Monorepos
  • Frontend: React · Next.js · Wagmi · Thirdweb SDK · TailwindCSS
  • Blockchain: Solidity · ERC-20/721/1155 · Tokenization · LayerZero (OFT) · Hyperlane · CELO · Polygon
  • DevOps: Docker · GitHub Actions · AWS ECS/RDS · Lambda
  • Tooling: CLI development · FastAPI scrapers · Git · Viem · Hardhat

🌱 Currently learning & building:

  • Cross-chain and L2 solutions (LayerZero, Axelar, CCIP)
  • Tokenized systems for real-world assets (ERC3643 - EIP-7493)
  • Improving my solidity level
