Designed a wireless, fail-safe system for remote control and monitoring where safety matters. The focus is deliberate human input, continuous connection checks, and automatic disarming to prevent accidental activation.

The architecture uses a handheld controller and a receiver communicating via ESP-NOW. A heartbeat mechanism verifies link integrity, and a state-machine control layer only enables outputs under explicitly safe conditions. Any invalid state or link loss forces the system back to a safe, disarmed mode.

Built with a “safety-first” mindset: clear arming states, explicit confirmation before output, and automatic disarm on disconnect. I can share diagrams, pseudocode, and implementation notes privately if needed.

Control-focused embedded work for rocketry-style test platforms, emphasizing reliability, validation, and real-world constraints. Work spans onboard sensing, servo actuation, and software tooling that supports repeatable testing and iteration.

Within GUA, my primary contribution was software—firmware, control logic, and tooling—plus coordination and planning. Mechanical design, fabrication, and CAD were led by my co-founder.

Platforms shown represent multiple iterations developed for stability, recovery behavior, and system integration—simulated before build, then refined through test feedback. Specific designs and CAD stay private; high-level engineering notes are available on request.
