Hello! I'm a Full Stack Developer specializing in Ruby on Rails, with 4+ years building and scaling production fintech systems. I own core backend architecture (Active Record, Sidekiq, Redis, PostgreSQL) and build React/React Native frontends end-to-end.
At Vita Wallet I helped scale a platform to $2B+ USD in processed transfers, building integrations with banks and exchanges across multiple countries, and writing automated test suites (RSpec, FactoryBot) to keep things stable.
More recently I've expanded into Web3: designing and auditing Solidity smart contracts for a DeFi governance protocol, with a security foundation using Foundry, Slither, and Aderyn - most of that work still wrapped in a Ruby on Rails admin backend with a Hotwire dashboard.
I use AI-assisted development tools (Claude Code, Codex) daily as part of how I ship. I also have 4+ years teaching Full Stack development, JavaScript, Python, and Solidity to large student cohorts (~20,000 students, ~80 cohorts), and a Mathematics degree that shapes how I break problems down.
