Senior🎓
Top SchoolRoberto Schneiders is a senior full-stack engineer with a 13+ year track record of shipping backend-focused systems across Ruby, Elixir, Go, Java and Delphi. He has led squads and delivery at e-commerce and retail platforms—driving GraphQL APIs, complex integrations with Shopify, Stripe, Shippo and Hyperwallet, and performance and CI optimizations that materially reduced cost and test runtimes. Comfortable from legacy Delphi migrations to cloud-native Rails services, he has architected multi-database setups, automated AWS infrastructure, and introduced reliability through Sidekiq, Docker and improved test suites. An active contributor to open-source projects, he implemented and hardened an API endpoint in the widely used BlockScout blockchain explorer and added robust proxy/error handling to a Delphi REST client. Based in Santa Catarina, Brazil, Roberto combines hands-on coding with mentoring and cross-functional communication, often surfacing product/requirement issues early to keep projects on course.
