Theodo is a web development team that builds and refactors web applications using Symfony, Angular/React, and Python. They focus on delivering business-ready web products quickly by agilely rewriting existing PHP code and turning it into scalable Symfony-based solutions. Their approach combines expert technical skills with an agile Scrum process, allowing rapid delivery from startups to multinationals.
