Sobre mí
I am a Web3 and software developer specializing in production-ready smart contracts and full-stack decentralized applications. I build secure Solidity contracts, automated trading bots, and scalable backend systems using Foundry, Python, FastAPI, and React.
I have hands-on experience delivering tokens, presales, staking and farming systems, wallet tools, and end-to-end Web3 products from architecture to deployment. My focus is security, clarity, and systems that work in the real world, not demos.
