About Me

I'm a Computer Science professional and mathematician, bilingual English–Spanish, with 5+ years building DevExp, full-stack, and backend systems across blockchain, AI, HR, agriculture, consulting, and e-learning. I lead projects and contribute to open-source.

In Web3 I work deep in the Ethereum stack — EVM clients (Geth, Reth), MEV, NFTs, tokenomics, DeFi — with hands-on experience writing smart contracts, optimizing gas, and shipping developer tooling. My background is grounded in algorithms, data structures, scalable architectures, and distributed systems.
