Joshua — Electro-Mechanical Technician

Architect of an advanced electro-mechanical framework utilizing complex sensor fusion. I engineered a closed-loop testbed integrating Teensy 4.0/Arduino microcontrollers with custom control panels. Using C++, CUDA, and Python, I built sub-millisecond data pipelines to process sensor telemetry. I wired 12V/24V DC power supplies and analog multiplexers, writing logic to execute real-time Proportional-Integral-Derivative (PID) motor control loops based on immediate physical feedback.

Operate multi-axis Siemens Sinumerik CNC grinders; actively edit G-Code at the terminal to adjust offsets, fix center, bump in/move out diameter, and correct Left Hand Height (LHH) for exacting structural tolerances; Inspect millimeter-wide lands on cutting edges; execute quality checks utilizing Digital Micrometers, Digital Calipers, Optical Comparators, and Mitutoyo 2-Axis Tool Scopes (dual-screw block zoom calibration); Dress and maintain Diamond Univel and D64 grinding wheels for optimal material removal; Assist in the electrical integration and maintenance of Siemens tooling heads, shielding and terminating wiring for automated steady rest grippers; Manage raw material staging and enforce shop-floor safety protocols, including emergency machine-stop procedures

Built and wired custom desktop control panels integrating 12V and 24V DC power supplies, analog multiplexers, and microcontrollers (Teensy 4.0 / Arduino); Designed and wired fluidic circuits using micro-diaphragm air pumps, 12V normally-closed solenoid valves, and MPX5010DP differential pressure sensors for automated pressure regulation; Developed high-frequency data pipelines using C++ and CUDA to process hardware sensor telemetry at sub-millisecond latencies, executing real-time PID motor control loops; Established localized ZeroMQ (ZMQ) asynchronous message buses to pass sensor telemetry across isolated hardware nodes

Operated industrial Tow Motors (Powered Industrial Trucks) to safely transport heavy chemical payloads through tight, high-traffic facility corridors; Executed regulated chemical sanitation of industrial pipes and mixing vats, adhering to HAZMAT, biological cross-contamination, and Lockout/Tagout (LOTO) safety protocols

Maintained strict facility control and direct life-safety accountability for vulnerable individuals in a zero-fail state medical compliance environment; Executed immediate crisis de-escalation and emergency behavioral protocols
