Work experience

Lead Mechanical Engineer/Mechanical Engineer at JL BILLET, INC., Apr 2021 - Dec 2025 · 4 yrs 9 mos, Poway, California, United States, In this role, I oversaw the design and development of numerous mass-produced goods for the JL Billet brand as well as a variety of other firearm companies and distributors. I innovated and customized several AK/AR/SIG Handgun components and accessories to enter untapped yet high-demand markets. I used standardized part families to ensure consistency and to make process interchangeability easier. I also produced detailed engineering documentation for all engineering process flows and standards. With the expectation of obtaining ISO/AS accreditations, I developed engineering standards, formats, and toolboxes for models and prints. Finally, I implemented a strong product data management system to reduce errors and improve responsiveness. • Executed R&D for several mass-produced products, including an optics side mount for the AK platform, selling over 1000 units within the first month, and a SIG P365 Grip module that was very well received at Shot Show, Las Vegas • Pioneered advancement of multiple new product lines, contributing to design, functionality, and production aspects. • Devised and engineered numerous tools, jigs, and fixtures to enhance manufacturing, quality control, laser engraving, and assembly operations. • Devised and optimized an engineering data organization system to enhance interdepartmental accessibility. • Ensured consistency and process interchangeability by standardizing over 10 different product families. • Generated designs and blueprints for various components, including tools, fixtures, floor aids, and more. • Enhanced over 50 SolidWorks models, drawings, assemblies, and other engineering data for pre-existing products. • Resolved engineering errors through the implementation of SolidWorks PDM and engineering process workflow. • Formulated JL Billet's part number naming system and developed a comprehensive database for documentation. • Introduced a robust review and accountability system for engineering changes.

Teaching Assistant at UC San Diego, Jan 2020 - Sep 2020 · 9 mos, San Diego, California, United States, At this position, I assisted the professor with the preparation and organization of instructional materials. Under the supervision of the professor, I assisted in the implementation of lesson plans and instructional activities. Taught classes on space mission analysis/design and spacecraft navigation as a substitute or for open hours. I was in charge of monitoring student progress and behavior, as well as providing comments to the professor on student performance and engagement. • Assisted students by addressing their technical, interpersonal, and other concerns. • Facilitated practice sessions, conducted open hours, and performed the role of substitute tutor. • Developed assignments, tests, and solutions to foster inclusive learning experiences for students.

Research Assistant at UC San Diego, Jan 2019 - Feb 2020 · 1 yr 2 mos, San Diego, US, During this job role at the LSDO Lab, I developed an OpenMDAO-based algorithm to optimize design/planning factors for three CubeSats to maintain accurate formations to function as 1 telescope gathering data from the sun. We utilized OpenMDAO, a gradient-based optimizer utilizing Attitude, Orbit, Propulsion, Solar, Battery, and Atmospheric prediction models built by me. • Published AIAA paper: “Large-scale multidisciplinary design optimization: Review and recommendations”. https://arc.aiaa.org/doi/10.2514/6.2019-3106 • Employed OpenMDAO to optimize propellant utilization for a 3-CubeSat formation control for telescope functionality.

Product Designer at Ensemble Furniture, Jan 2017 - Sep 2017 · 9 mos, Chennai, Tamil Nadu, India, As a Product Designer at this modular furniture startup I: • Engineered desk chairs specifically tailored for the student population in town, selling over 1500 units in 6 months. • Devised and developed a cost-effective modular bedframe, generating sales of over 1000 units in 8 months.

Research Intern at Armament Research and Development Establishment (ARDE), DRDO, Dec 2016 - Jul 2017 · 8 mos, Pune District, Maharashtra, India, Working with the artillery department in the process of developing a new-age towed gun system, I was responsible for developing solutions and simulations to optimize the thermal performance of the barrel. During my internship I: • Conducted R&D on temperature control, measurement, and simulation in the barrel of a gun system. • Engineered precise experimental configuration to measure in-bore temperature for artillery gun system. • Explored burst fire limits and barrel failure for an artillery gun using heat transfer simulation on Ansys Workbench. • Published a research paper on “The study on Barrel Heat Transfer and Temperature Measurement Techniques in Gun Systems” in the ARDE technical reports database.

Manufacturing Intern at Milacron, Dec 2015 - Jul 2016 · 8 mos, Ahmedabad, Gujarat, India, Starting my experience in the field of Mechanical Engineering here, I spent some my time on the shop floor and interacted with several operators, programmers, and department heads to understand the functioning of state-of-the-art subtractive machining processes of turning and milling. During this internship, I also: • Observed and studied the use of Computer Numerical Control (CNC) manufacturing. • Streamlined barrel adapters’ setup time by 10% (4200 min./year) through the implementation of a fixture specifically engineered for VMC.
