## Story

At EOS Costa Rica, I helped launch the EOS mainnet and operated validator infrastructure across EOSIO-based networks.
I built a private EOSIO blockchain for the innovation labs of a global accounting and consulting firm. The implementation used Azure, Terraform, EOSIO, and React, delivering an MVP for intercompany transactions and tax workflows involving a stablecoin, cryptographic hashing, and IPFS.
I also contributed to open-source tooling and developer relations, including the EOS Rate application and technical workshops connected to Costa Rica's blockchain community.
