Summary
🤩
Rockstar🎓
Top SchoolEric Dallo is a Staff Software Engineer based in São Paulo with 11 years of experience building developer tooling and language-server ecosystems. At Nubank he combines leadership and hands-on engineering, while as an open-source maintainer he drives major projects like clojure-lsp, emacs-lsp and contributions to clj-kondo and lsp4j that improve code completion, refactoring and semantic tokenization for Clojure and other languages. A longtime Emacs and NixOS enthusiast, he blends deep editor-side expertise (lsp-mode, dap-mode, lsp-ui) with backend protocol work to enhance developer experience across editors and IDEs. He is known for pragmatic, low-level improvements—such as unused-namespace detection, semantic tokens and Dart/Flutter LSP support—that quietly raise productivity for large codebases.
