Senior🎓
Top SchoolThadeu Esteves is a Senior Software Engineer with 11+ years of hands-on experience building and scaling web applications, specialized in Ruby on Rails and cloud-native architectures on AWS. He combines backend and frontend expertise—shipping performant APIs, realtime dashboards, and VoIP features—while rigorously applying OOP, SOLID principles, and test-driven practices with RSpec and CI/CD. At Atende Simples he drove significant cost and latency improvements by migrating services off Heroku to AWS/Dokku, optimizing Lambdas and caching layers, and implementing high-throughput features like a Power Dialer that orchestrates thousands of calls/second. A certified AWS and Redis user and active open-source contributor (author of branca-ruby), he also brings practical knowledge of realtime systems (Ably, WebRTC), queues (Sidekiq, SQS), and encryption patterns. Fast-learning and organized, he pairs strong troubleshooting and system-design skills with a track record of mentoring teams on OOP, functional approaches, and operational cost controls.
