I study Mechanical Engineering and Computer Science at Harvard, and I’m interested in designing thoughtful hardware products and systems — from robotics to consumer devices.

Selected Projects

Harvard ES51 —Turf Wars Robot

A remote-controlled robot designed for object manipulation and pick-and-place tasks, built to compete in Harvard’s ES51 Turf Wars competition.

Keutsch Lab — Stratospheric Particle Exposure Analysis Device

Keutsch Lab — Stratospheric Particle Exposure Analysis Device

A high-altitude balloon payload designed to expose and analyze particle samples under stratospheric UV, pressure, and thermal conditions in support of emerging solar engineering research.

Microrobotics Lab — MDEA Gantry

Microrobotics Lab — MDEA Gantry

A modified gantry system that automates and safely encloses the production of multilayer dielectric elastomer actuators (MDEA) for microelectronics manufacturing.

Harvard ES50 — Glow Grid

A reactive, sensor-driven LED dance floor that responds to user interaction and logs engagement metrics, developed for Harvard’s ES51 course.

Experience

Industry

Amazon Grocery Robotics & Automation

May - August 2025

Hardware Development Engineer Intern

Developed an autonomous robotic picking system fully integrated with vision, motion control, and end-of-arm tooling

  • Designed and developed a custom suction end-effector (EOAT) in SOLIDWORKS, optimizing geometry, materials, and vacuum flow for handling of irregular grocery items
  • Conducted mechanical validation testing to quantify eligibility (80%), handling accuracy (95%), and throughput improvement (35%), ensuring compliance with performance and reliability targets
  • Supported iterative design-for-manufacturing (DFM) refinements through rapid prototyping and testing cycles
  • Partnered with the computer vision team to enhance object recognition and pick-point algorithms, improving system repeatability and mechanical alignment
  • Coordinated with external vendors to source specialized materials and machine critical components

Harvard Reimagining Experiential Education & Fabrication (REEF) Makerspace

August 2024 - Present

Maker Fellow

Trained and advised others in the Harvard SEAS Reimagining Experiential Education & Fabrication (REEF) Makerspace to machine their academic and personal projects. This includes training in laser cutting, dye sublimation, 3D printing, wood shop machinery, casting, soldering, hand tools, etc.

Amazon Robotics & Mechatronics

May - August 2024

Hardware Development Engineer Intern

Designed multi-camera presentation array, replacing previous scan tunnels to increase item eligibility by over 25%.

  • Applied DFM/DFA principles to create camera array fixture using SOLIDWORKS adhering to project requirements
  • Assembled fixture prototype and subsequent design reiterations
  • Evaluated performance of varying camera arrays by DOE: performing rate tests, creating heat maps of camera blindspots, and measuring item eligibility, eventually recommending a solution to AMAZON fulfillment centers
  • Collaborated with external vendors to procure materials and machine precision components

Lockheed Martin Aeronautics

May - August 2023

Product Quality Engineer Intern

Revamped radar processing chips manufacturing process for high manufacturing yield and quality.

  • Performed a Design of Experiments (DOE) to test different parameters (e.g., pressure, temperature, resin mix)
  • Used python to analyze wafer-level and package-level test data to identify trends affecting semiconductor yield
  • Developed automated dashboards which enabled real-time alerts for anomaly detection to flag defective chips early

Lockheed Martin Aeronautics

August 2021 - August 2022

Facility and Plant Engineer Intern

Strategized production reliability by analyzing previous equipment failures and implementing new preventative maintenance strategies.

  • Developed mapping system by creating CAD asset map databases in Microstation for over 40 buildings and 300 assets at LMCO Aeronautics Headquarters
  • Strategized production reliability by analyzing previous equipment failures and implementing new preventative maintenance strategies
  • Created preventative capital budgets for production line equipment based on analysis of system failures & risks

Research

Harvard Keutsch Lab

Aug 2024 - Present

Undergraduate Researcher

Created an opening/closing capsule for a high-altitude balloon (HAB) system that automates the process of exposing chemical samples to the stratosphere upon ascension and safely returns to the troposphere.

  • Qualified materials for UV, temperature, and pressure environments in bench, chamber, and flight tests
  • Iteratively refined SOLIDWORKS assemblies and manufacturing drawings based on test data and mechanical performance feedback
  • Applied Design for Assembly (DFA) and Design for Manufacturing (DFM) principles to improve system robustness and simplify fabrication

Harvard Microrobotics Lab

October 2023 - May 2024

Undergraduate Researcher

Modified a 3D printer to automate multi-layered dielectric actuator elastomer (MDEA) production, a process for producing microelectronics currently performed by hand.

  • Designed conceptual CAD for modified 3D printer gantry in SOLIDWORKS to account for airtight enclosure, integration of new electronics and pneumatic controls, tray sliding mechanisms, etc.
  • Prototyped and assembled the modified printer using water jet, laser cutter, vertical and horizontal bandsaws, drill presses, and 3D printers
  • Modified existing 3D printer Gcode to accommodate new hardware
