WORK EXPERIENCE

Mechanical Engineer – 11 Health and Technologies Inc., Irvine, CA (Apr 2019 – Nov 2020)

• Designed and Prototyped fixtures using commercially off-the shelf components, to test and validate electronics.

• Calculated the force required to couple two parts of a removable wearable. Validated the force value using Ansys.

• Worked closely with three different vendors to streamline the high-volume manufacturing process of smart ostomy appliance to build about 100,000 units per year. Developed non-invasive, fast, accurate quality inspection test methods.

• Developed cost-efficient, plastic couplings and sensor casing compatible with injection molding manufacturing process.

• Drafted the component and assembly drawings of the wearables to be compliant with the chosen manufacturing processes like injection molding, heat welding, etc. Performed tolerance stack-up analysis to verify the chosen tolerance values. Mechanical Engineer Intern 2 – Lam Research Corp., Tualatin, OR (May 2018 – Dec 2018)

• Designed, prototyped, and validated a calibration fixture that reduced calibration time in field and manufacturing by 70%.

• Developed a precision hydraulic circuit to dispense water for process control application in a semi-conductor wafer fabrication step. Hydraulic circuit was controlled using a pneumatic circuit. This module was encased in a plastic enclosure.

• Conceptualized the mechanism to make 5 load-bearing members of a machine frame, removable. Performed truss analysis to determine loading in each of the removable members as well as the loading condition of the frame.

• Designed and prototyped an electro-mechanical box to house a sensor controller for high voltage application. Box housed both power and control elements of the electrical circuit, followed all electrical safety methods.

• Redeveloped robot hoist to replace an obsolete winch motor with newer, efficient motor. Verified the required specs of the motor by analyzing the load on the motor. Analyzed the hoist arm to confirm no increased stresses due to new motor. Mechanical Engineer 1 – Lam Research India Pvt. Ltd., Bengaluru, India (July 2014 – Nov 2016)

• Production released about 15 advanced modules and structured them to configurable BOM without affecting supply chain.

• Redeveloped the layout of a hydraulic module to add additional process elements into the existing layout of the module. This module also contained elements of pneumatic and electrical circuits to control the hydraulic circuit.

• Designed the mechanical elements of a portable AC box containing both power and control elements. Performed structural analysis to ensure that the module can handle loads, performed tip-over analysis, and air flow analysis inside the box.

• Replaced ~15 obsolete OEM components with no drop-in replacements with innovative design methods as part of continuous improvement process and to sustain the modules.

• Drafted and updated 2D drawings in Creo with using GD&T dimensions. Defined necessary manufacturing symbols like welding symbols, surface finishes, GD&T symbols, etc. where necessary. Page 2 of 2

• Conceptualized and developed CAD models of concept devices for sperm washing process part of IVF procedure which eliminates the utilization of centrifuge for separating the sperms.

• Fabricated the concept devices using 3D printing, & plastics fabrication methods utilizing bio-compatible material. ACADEMIC PROJECTS

Foldable and Portable e-bike, PES Institute of Technology

• Conceptualized the structure of e-bike and developed the folding mechanism in a 3-member team.

• Developed mathematical model for the e-bike applying the loading condition of a standard male in Hypermesh leveraging 1D, 2D and 3D elements. Analyzed the mathematical model in MSC Nastran with all the degrees of freedom arrested.

• Fabricated a working prototype using manufacturing operations such as welding, cutting, machining, drilling, fastening, etc. Concept to prototype in less than 3 months to demonstrate the feasibility of the bike and received appreciation. Hyperloop at USC - Structures Team Lead, University of Southern California

• Conceptualized and designed mechanisms to control the lateral and transverse motion of the pod in the hyperloop tube.

• Designed 3 braking systems viz. wheel, emergency, and motor regenerative braking. Computed necessary brake power.

• Developed test strategies to evaluate shaft behavior for high speed application, and wear rate of brake pad material. Team HAYA Off-Road – Team Captain and Power Train Head, PES Institute of Technology

• Developed the power train of Baja car using CVT with FNR Gear box as transmission achieving a top speed of 59.5 km/hr.

• Performed structural analysis of the space frame for frontal, rear, side impact, roll and modal analysis using Ansys Solvers.

• Analyzed front and rear suspension control arms, and wheel uprights for their respective loading conditions.

• Fabricated the car leveraging fabrication & assembly techniques in conformance with design & participated in SAE event. Drive by Wire Steering System, University of Southern California

• Evaluated drive-by-wire steering system with Ackerman Steering Geometry to accomplish desired steering angles.
