Senior🎓
Top SchoolLonderson Araújo is a seasoned Ruby on Rails developer with over a decade focused on Rails and 13 years of professional experience building and modernizing web applications from monoliths to microservices. He has led teams and engineered complex full-stack solutions—most recently implementing a multi-country tax system using Rails, React, PostgreSQL, Elasticsearch, Sidekiq and AWS—while consistently improving legacy codebases and delivery practices. Comfortable across DevOps, caching, background processing and testing (Redis, RSpec, Heroku), he excels at performance tuning and pragmatic architectural shifts that unlock new capabilities. Based in Santa Catarina, Brazil, he pairs hands-on coding with mentorship and code review, having driven Rails upgrades and large refactors in production environments. An interesting detail: he applies disciplined productivity techniques (like the Pomodoro Technique) learned early in his career to sustain focus when managing many service modules and tight release schedules.
