About

I am a senior studying Computer Engineering at Wentworth Institute of Technology who focuses on embedded systems and robotics, with experience in both software and hardware.

I hold leadership roles in extracirruculars such as Tau Beta Pi and the Wentworth Engineering Honors Society, meaning I am always involved on-campus. I take my work seriously, and like to tackle diverse challenges to gain new skills.

Ask me about "Tetris" at your own risk.

Multi-Layered Systems

A collection of the projects I have worked on over the years, ranging from signal generation to mechatronics. I like to learn about the various efforts that bring ideass from research to production.

A Deeper Dive

Search and Rescue Robot

ROS2
ESP32
Mechanical Design

My group's current senior capstone: a semi-autonomous search and rescue robot. I have worked on designing versatile robotic joints with 4 DOF's per leg, as well as programming ESP32 LoRa communication.

Tau Beta Pi Chapter Founder

Wentworth Institute of Technology | March 2026

A year of hard work resulted in Wentworth's first initiation of 23 Tau Beta Pi members, each selected for their outstanding character and exceptional skills. As the chapter's founding president, I have opened the door to prestigious opportunities for Wentworth's engineering community.

"Tau Beta Pi is truly grateful for your leadership of the local honor society at Wentworth." - Curt Gomulinski, Tau Beta Pi Executive Director

Technical Support Engineering Intern

Harvard University Information Technology | Fall 2025

My second co-op at Harvard expanded on my previous experience, focusing on hardware repairs, 1-on-1 consultations, and project management. I was able to implement 3 new workflows including international equipment setup, routine inventory audits, and a new user feedback evaluation.

"Detail oriented, very tactful, highly accountable for his work. Ethan did a lot of work for the Walk In Support Center Fall startup." - Lillian Delgado, Walk-In Support Center Manager

Wentworth Engineering Honors Society

Wentworth Institute of Technology | July - November 2025

The local honors society under Wentworth's School of Engineering recognizes students with strong academics and dedication to community. Having been recognized in summer of 2025, I became the society's treasurer, working to budget for events and keep track of our private funds.

"To be honest, I am not really surprised by his fantastic job at the Convention; he is excellent." - Dean Khabari, School of Engineering
