• Supported a prototype-to-product transition for a Direct Air Capture subsystem, improving compactness, modularity and manufacturability. • Redesigned a drying/thermal subsystem, achieving 50% footprint/volume reduction and 20% heat-loss reduction through thermal design and insulation improvements. • Evaluated and improved a heat-exchanger configuration using LMTD-based analysis and experimental data interpretation; informed design iterations with data-driven trade-offs. • Improved reliability and serviceability by standardizing piping/interfaces and mechanical mounts; automated test-data processing with Python
