About

name:        Ary Rabelo
role:        Senior Full-Stack Engineer
experience:  20+ years shipping production software
rails_since: 2012
core:        [Ruby on Rails, React, TypeScript, GraphQL, PostgreSQL, Redis]
also:        [Python, Elasticsearch, Playwright, CI/CD, AWS]
location:    Brazil   # full overlap with US business hours
focus:       Ship reliable products. Anti-hype. Use AI where it actually helps.
status:      open to senior full-stack roles

I take ambiguous problems, ship solutions that hold up in production, and follow through. Most recently Senior Software Engineer II at Canix (2024-2026). Earlier, built and scaled my own product from zero to 1.8M+ monthly visits.

Featured work

"MCP vs a CLI: the token cost" Measured write-up: the MCP carried ~17x more tokens per call than a CLI Essay

Recent writing

Most production work lives in private repos — what's public here is a representative sample. Happy to walk through the rest.
