Mechanical Design Engineer | KB-BERG

I designed a mechanism to mechanically synchronize the linear movement of the both jaws of a Bag gripper for Industrial robot, ABB IRB 460.

I made manufacturing drawings for 3 major components in the Bag gripper as a Test Drive.

Mechanical Design Engineer | MoonHub Technologies Ltd.

I designed the CAD models of the cases for the M-300 through the M-2000 models of MoonHub’s Battery - integrated Inverter Systems.

I collaborated with the Electronics Engineer to optimize the system airflow through analysis and simulation of the CAD models, leading to 30% improved thermals of the system.

Part Design Engineer | Desall

I designed an innovative nebulization cap for compressible plastic bottles to meet diverse client needs for manual misting.

I collaborated with the Mechanical Engineer to create spiral geometry and a Vortex Chamber in the Cap in CAD software to enable nebulization of liquids hand-squeezed from the bottles into a fine mist.

The Hybrid HEX | NASA Cryogenic Recuperator Concept

As part of a NASA challenge to design a cost-effective recuperator without sacrificing thermal performance, I developed the Hybrid HEX—a novel cryogenic heat exchanger combining the high initial heat transfer rate of parallel flow with the superior final cooling effectiveness of counterflow.

Using CFD analysis, I identified a crossover point where parallel flow rapidly preconditions the fluid, after which counterflow takes over to drive near-complete heat exchange. To enable this transition, I bridged the two flow paths, creating a hybrid flow. This design ensures rapid initial cooling followed by sustained thermal performance throughout the exchanger length. The Hybrid HEX achieves a 12% size reduction at equal effectiveness or a 20% increase in effectiveness at equal size compared to counterflow designs.

The J-W Latch | NASA ESTO Advanced Component Technology (ACT)

As part of a NASA challenge to develop a controlled latching mechanism for sequential antenna panel deployment in space, I designed the J-W Latch to ensure each panel is released only after the previous one is fully secured.

This Latch features a docking-triggered mechanism with a spring-loaded J-Pin seated in a locking groove within a preloaded W-Latch. A tapered Key, integrated into the docking system, engages the J-Pin during deployment. As it advances, the Key compresses the spring-loaded J-Pin; if it retracts prematurely, the J-Pin snaps back into the groove, preventing release. Once the Key fully clears the J-Pin, the W-Latch triggers, allowing the next panel to deploy. This sensor-free mechanism relies entirely on geometric interaction and spring forces.

The Limb | NASA Super Heavy Logistics Transport

As part of a NASA challenge, the objective was to design a heavy-duty transportation system capable of moving a 100,000 kg Common Habitat module across 5 km of unprepared lunar terrain—handling slopes up to 20°.

I developed The Limb, a robust cable-crane heavy lift system engineered for unprepared lunar surfaces. It features dual cranes with crane-to-crane transfer capability and deployable outrigger legs for stable operation on uneven terrain. This system is optimized for the Common Habitat Architecture, enabling secure, step-wise payload transfer directly from the Starship to the deployment site, providing stable and controlled transport across challenging surfaces.

Development and Computational Assessment of Temperature Performance of a Novel Heat Exchanger Flow

This study presents a novel flow configuration that can be integrated into existing heat exchanger designs, enabling cost reductions of over 12%. The proposed flow path achieves maximum effectiveness comparable to counterflow heat exchangers, while offering either increased compactness at equal effectiveness or improved thermal performance for the same exchanger size.

Analytical and Computational Evaluation of Flat and Toroidal Drone Propeller Performance

This study compares the performance of flat and toroidal drone propellers across three blade configurations using analytical and computational methods. Toroidal propellers demonstrated a significant lift advantage, generating 6–77% more thrust than flat propellers. However, they exhibited lower efficiency, with flat propellers producing 45–64% more thrust per watt across all configurations.

CFD Simulation of Segmented Articulating Blade Tips in Wind Turbines

This study compares Fixed and Segmented Articulating Blade Tips (SABTs) in large-scale wind turbines using computational methods. At a rotor diameter of 161 m and wind speed of 3 m/s, SABTs generated 82,812 Nm of CCW torque from the outer 15% of each blade—over twice that of fixed tips—by rotating three slotted segments to optimise the angle of attack, while neutral and negative angles reduce drag at rated speeds and provide a fail-safe in high winds.
