Web3 Architect & Solidity Engineer — from pre-sales to hands-on shipping

I bridge business and engineering. After a senior pre-sales/architecture track, in 2017 I moved into hands-on development to build Web3 dApps and smart contracts that solve real problems.

• ZKProof Credit App (2025) — React/Circom: prove “salary ≥ threshold” without revealing the salary. On-chain verifier on Sepolia.

• RFP/Tender dApp (2022→2023) — Next/Solidity: client-side encryption + Irys (ex-Bundlr). Currently archived after breaking vendor changes; partial migrated.

• Gubbi Pay (ETHMexico 2024)— Hackathon. Swap contract on Avalanche recognized by Avalanche

• RWA ERC-1155 (Base LATAM 2024) — Hackathon.. Asset tokenization with community mention.

I’m comfortable owning architecture and also shipping full-stack (Next/React/TypeScript, wagmi/viem, ethers, Hardhat/Foundry). Privacy and correctness matter to me (client-side encryption, tests, deploy/verify scripts). Open to Web3 roles (Architect, Solidity, Full-Stack) — and Web2 when it’s the right fit. Prefer remote, open to relocation.
