Ioannis S is a SOC Analyst and open-source enthusiast based in Athens with nine years of experience blending security operations, digital forensics, and developer tooling. He has hands-on SOC experience in military cyber incident response and has developed attack surface management and license-plate recognition tooling, now continuing his security career at Neurosoft. Equally at home in Vim and Neovim internals, he is a prolific contributor to high-profile projects like tree-sitter and neovim, adding filetype support, syntax improvements, and integrations such as Kotlin formatter/linters to null-ls.nvim. His work reflects a rare mix of low-level editor build/config expertise and practical security engineering, and he evangelizes Kotlin while crafting efficient tooling workflows with Vim. Colleagues know him as a pragmatic problem-solver who turns nuanced file-format and build-system issues into reliable developer-facing features.
