Hardware Architecture & System Design
Complete board design, embedded systems, low-power optimization, PRD authoring, and prototype-to-production execution.
Test Automation & Global Commissioning
Custom test stand design, automated validation software, PLC programming, and remote overseas factory commissioning.
Advanced Thermodynamic Systems
Custom heat pump architectures, A2L refrigerant safety compliance (UL 60335-2-40), single-EXV control routines, and sol-air thermal modeling.
Turnkey Execution & Vendor Alignment
Multi-disciplinary physical integration, vendor RFQ preparation, Design for Manufacturability (DFM), and factory handoffs.
Micro Heat Pump & Embedded Architecture
Architected an ultra-compact, multi-mode micro heat pump utilizing eco-friendly A2L refrigerants (R1234yf), custom single-EXV closed-loop control, and autonomous sub-zero oil protection routines.
40-Station "Island of Automation"
Architected a 40-station U-shaped universal lifecycle test rig with hybrid PLC and National Instruments PXI scope instrumentation, short-run pneumatic manifolds, and auto-sensing DAQ.
Energy Harvesting Patent (Organic Rankine Cycle)
Concepted, prototyped, and empirically validated a novel Organic Rankine Cycle energy-harvesting thermal system in a psychrometric chamber, securing an issued U.S. Patent.
Overseas Factory Commissioning
Designed and built automated production validation rigs. Remotely shipped, installed, and commissioned full testing suites at an overseas manufacturing plant in India with zero travel overhead.
