Backend & Web3 Engineer skilled in Python (FastAPI), blockchain data integrations, and on/off-chain automations. I build secure APIs and dApp backends that connect Web2 systems with Web3 — from smart contract listeners to crypto payment flows. Experienced with FastAPI/Node, PostgreSQL/MySQL, Docker, GitHub Actions, and NGINX. I integrate EVM chains (Ethereum, Polygon, BSC) using Web3.py, ethers.js, Covalent, Alchemy & Infura. I also automate workflows via n8n, webhooks, and async workers. Clear documentation, Postman collections, and fast communication in English/Spanish. Bring your manual process, flaky integration, or blockchain idea — I’ll turn it into a clean, reliable, and production-ready backend.
