Rockstar🎓
Top SchoolTatsuya Yamaguchi is a Drone Software Engineer with a decade of experience building firmware, ground stations, and tooling for ArduPilot-based systems, combining hands-on C++/C# development with technical writing for open-source projects. He has contributed notable features and bug fixes to core ArduPilot repos and Mission Planner—adding sensor integrations, failsafe behaviors, and telemetry-driven UI optimizations—while also improving project documentation. A repeat award-winner in Japanese drone competitions (including delivery and discovery missions), he pairs practical field experience with formal training under ArduPilot mentor Randy Mackay. Based in Saitama, Japan, he transitioned from security and enterprise support roles at Sprout and Microsoft to freelance drone engineering, bringing a systems-design master’s perspective to autonomy problems. An uncommon strength is his blend of low-level firmware fixes and full-stack ground-station improvements, enabling end-to-end drone feature delivery.
