Core Skills
Professional Experience
Stoke Space
Oct 2022 – Jan 2025Test Technician III / Rocket Specialist
Kent, WA & Moses Lake, WA
- Helped define hardware test requirements and supported Python/GitHub automation workflows to improve repeatability during injector and thruster test operations.
- Designed and proofed custom pressure panels, test fixtures, and 3D-printed jigs using NX CAD to support repeatable hardware validation and controlled test execution.
- Captured telemetry and reviewed diagnostic data, standardizing documentation and transitioning test procedures from OneNote to Boltline execution software.
- Drove root-cause anomaly resolution by generating rapid issue tickets, ensuring stable sustaining test operations and minimizing test downtime.
- Owned hardware preparation and test article installation across mechanical systems, maintaining strict hazard controls, standby helium purges, and double-block-and-bleed procedures across LOX, LH2, and GOX systems.
SpaceX
Feb 2020 – Sep 2022Integration Test Technician IV
Starbase, TX
- Executed structured test procedures and system-level functional checkouts on end-to-end fluid systems and pneumatic actuators, completing strict WarpDrive final closeout and pass/fail documentation.
- Analyzed hardware defects and flight-readiness risks; diagnosed a critical pre-valve design flaw where an extruded chamfer gap caused yielding, escalating photo-documented evidence to engineering.
- Troubleshot complex system-level hardware anomalies, identifying an incorrectly clocked IMU prior to flight operations and driving corrective action through visual defect reporting.
- Designed and deployed operation-specific tooling kits and reference guides that improved integration readiness and helped cross-functional technicians execute complex integration work.
- Supported repeated Raptor engine installations, engine remove-and-replace (R&R), and subcomponent rework operations to maintain high-tempo Starship/Booster launch and integration campaigns.
- Coordinated with NDT teams via engineering issue tickets to validate critical structural welds and flight vehicle hardware.
Army National Guard
Jun 2014 – Jun 2020Heavy Weapons Team Leader | Airborne-qualified
Weslaco, TX
- Led and supported field operations under pressure while maintaining accountability of personnel, weapons, vehicles, and sensitive equipment.
- Built leadership, communication, safety, and risk-management discipline through infantry/heavy-weapons training, reconnaissance exercises, and team-level operations.
- Recognized as Honor Graduate of the 11B10 MOS Transition Course; completed additional safety and military operations training.

Active DevelopmentWearable AI + Embedded Hardware Prototype
- Designed and built a three-node distributed embedded system: XIAO ESP32-S3 acoustic capture, Python Flask / OpenAI Whisper ASR inference, and a wrist-mounted 4.3″ 800×480 LVGL display.
- Engineered a parallel-rail dual-MCU power topology from a single 3.7V LiPo cell, including a hardware protection-diode bypass for direct battery-rail injection.
- Conducted a hazard operability analysis (HAZOP) identifying the USB back-feed path as a LiPo cell back-charge hazard during concurrent display-side firmware operations; implemented a mandatory battery-disconnect procedure as a formal hazard control.
- Developed Arduino/C++ firmware with HTTP polling, SD card Binary RGB565 image loading into an 800 KB PSRAM framebuffer, and LVGL immediate-flush rendering.
- Implemented lexical trigger classification in Python using Whisper tiny.en for voice-to-display command routing with ~2–3 s end-to-end latency.
- Validated power paths and display initialization on a regulated bench supply before sealed enclosure integration.
Pneumatic Solenoid & Servo Actuation ControllerView ↗
CompletedEmbedded Hardware Prototype · Open-Source
- Designed and assembled an Arduino Uno-based multi-channel actuator controller operating at 150 PSI supply / 80 PSI working pressure, driving a normally-closed (NC) fail-safe solenoid valve and dual rotary servo actuators via PWM on digital pins 10 and 11.
- Engineered an automotive-grade SPST relay (Bosch form factor, AutoZone) as an interposing switching element between the DFRobot motor driver H-bridge and solenoid coil circuit — required because the shield output could not directly sink the valve's inductive inrush current.
- Authored a 23-step commissioning procedure with annotated photo documentation covering shield installation, relay wiring, solenoid conductor termination (4.5 mm strip spec), 9V power architecture, servo pinout verification, and breadboard harness integration.
- Performed a hazard operability analysis (HAZOP) at 150 PSI — identified three hazard scenarios including firmware hang-state energization and tank over-pressurization; mitigated via NC fail-safe valve topology, firmware stop-command de-energization, and a mechanical relief valve on the compressed-air reservoir.
- Implemented a UART-serial dispatch protocol for enumerated solenoid actuation modes — toggle, forward/backward burst, cyclic test, and stop — enabling repeatable functional verification without firmware re-upload.
- Completed functional verification checkout validating solenoid quality and full servo angular displacement envelope (0°–90°) per documented protocol.
- Open-sourced firmware and commissioning documentation for community replication.
Autonomous Aquatic Platform (AAAP)
In ProgressComponent-Level Robotics Prototype
- Built a control prototype utilizing a Node.js dashboard and custom serial protocol to transmit precise control commands to an embedded ESP32 architecture.
- Integrated NVIDIA edge compute for onboard computer vision inference, targeting real-time autonomous navigation and obstacle detection.
- Executed embedded subsystem functional testing on ESC, servo, and DC motor control logic, validating critical firmware safety interlocks and multi-rail power architecture.
- Documented bench-test steps to independently validate GPS/IMU diagnostic telemetry prior to final hardware integration.
- Note: Final hardware integration, waterproofing, and aquatic field validation are currently pending.
