Ruby on Rails Developer with 4+ years building fintech systems at scale, and increasingly building the AI-augmented workflows that make that work faster. Backend owner at Vita Wallet, building Active Record data models, Sidekiq background jobs, and Redis-backed infrastructure behind a platform that scaled to $2B+ USD in processed transfers. Full stack when the product needs it: React, Next.js, TypeScript. More recently, Web3: building and auditing 28 Solidity smart contracts for a DeFi governance protocol, catching reentrancy and denial-of-service vulnerabilities with Slither and Aderyn, testing with Foundry — still built in Rails there too, with a Hotwire dashboard. Hands-on daily use of AI-assisted development tools (Claude Code, Codex) as part of how I ship. A Mathematics degree (Universidad de Antioquia, first-place thesis defense in Mathematical Logic) shapes how I break problems down, and 4+ years teaching Full Stack and Blockchain to ~20,000 students across ~80 cohorts shapes how I explain them.
