Forward Deployed Engineer Roadmap

A practical six-month intermediate-to-advanced roadmap for software engineers preparing for Forward Deployed Engineer responsibilities. Build one customer-facing product while developing production engineering, integrations, applied AI, deployment, technical discovery and customer-delivery skills. This roadmap assumes prior programming, API, database, Git and deployed-project experience; it strengthens FDE readiness but does not promise a direct FDE role.
