    Robot Car - 2.007 Design & Manufacturing

    Spring of 2025, I took MIT course 2.007 - Design & Manufacturing, and designed, fabricated, and programmed a robot (affectionately dubbed “Big Homie”) capable of both remote control and autonomous operation, eventually winning the Glinda Prize for “the most elegant, regal, and stunning robots” in the competition

    Autonomous Navigation & Control Systems Project

    Fall of 2024, I took MIT course 16.632 - Autonomous Machines, where I completed various investigations with a variety of sensors (IR, Ultrasonic, IMU) and completely functioning, small-scale autonomous machines utilized for in-class implementation/testing of control algorithms (PID, Bang-Bang, State Machines)

  • Metal 3D Printing Internship

    Summer of 2025, I had the incredible privilege of working as a Mechanical Engineering Intern at studio 3e8 through the MIT Martin Trust Center for Entrepreneurship’s Pozen Fellowship. While there, I assisted the team on various projects, both technical and entrepreneurial.

SOFTWARE DEVELOPMENT + AUTOMATION

    LearnWell Admissions Bot

    In August 2025, I developed a RAG-based AI chatbot modeled after my voice and consulting approach to provide clear, actionable guidance for underrepresented and ambitious college applicants. I built and deployed the JavaScript and Python-based backend API on Vercel, and integrated the frontend through XML with my website on Squarespace, enabling visitors to engage with the chatbot in real time.

    Studio 3e8 — Workflow Automation Tools

    To streamline remote monitoring of active 3D prints, I built a lightweight alert system that pushed real-time status updates to Slack. Using TypeScript and SQL, I scripted database polling to detect state changes and integrated with the Slack API to post updates like print start and completion. The system enabled frictionless, multi-device monitoring, reduced manual check-ins, and—after refining the logic to trigger at critical instances —cut message noise by 80% while improving response efficiency.

  • Turing-Complete Scheme Interpreter

    Fall of 2024, I Designed and implemented a Turing-complete Scheme interpreter, supporting arithmetic operations, control flow, lambda expressions, recursion, and file imports.

    Developed and optimized algorithms to improve execution efficiency, demonstrating proficiency in data structures, iteration, recursion, and time complexity analysis
