A Decade at the Edge of Physics and Hardware

EOL & Atmospheric Demise Architecture

Amazon Kuiper Manufacturing LLC | Seattle, WA

Lead Systems Engineer, Re-entry & Demise

Spearheading the end-of-life (EOL) and atmospheric demise architecture for large-scale satellite constellations, ensuring 100% compliance with global debris mitigation standards and FCC/ITU regulations.

Leading the cross-functional development of thermal and structural demise simulations to predict spacecraft fragmentation behaviors, optimizing component design to minimize ground casualty risk. Developing automated trade-study frameworks to evaluate re-entry survivability across diverse hardware configurations, bridging the gap between high-level mission requirements and detailed subsystem manufacturing.

Where I First Encountered the Manufacturing Bottleneck

Godrej & Boyce Mfg. Co. Ltd. | Mumbai, India

Graduate Engineer Trainee & B.E. Project Trainee

Graduate Engineer Trainee (07/2012 - 07/2013): Handled end-to-end capital procurement and developed cost models with annual net savings of 10%+.

B.E. Project Trainee (11/2011 - 04/2012): Achieved 40%+ daily production increase through FMEA-driven process redesign. Reduced lead time to order dispatch by 1.5x. This experience revealed the fundamental disconnect: engineering constraints are not just physics — they are manufacturing systems. The precision component assembly line taught me that the limiting factor is rarely the theoretical limits of physics, but rather the operational complexity of translating design into production.

This is where the thesis began: the manufacturing bottleneck is systemic, not technical. The constraints on production are not limitations of physics, but limitations of systems design and operational execution. This foundational experience informs everything that came after.
