I'm a Passionate Engineer
I’m Justin, a graduate of Dartmouth College and Bard College with dual degrees in Computer Engineering and Computer Science. My work bridges software, data, and hardware, and I’m motivated by building systems that have measurable impact in the real world. I’ve led projects spanning embedded systems, power electronics, and full-stack software. From developing a wireless power platform for electric motorbikes at Nucular Tech to creating machine learning pipelines that predict gentrification trends across New Jersey. Whether working on a application or a data model, I focus on delivering reliable, scalable solutions that solve meaningful problems. I’m driven to learn, build, and explore new ideas, thriving on independence and self-direction — it’s how I continue to grow as an engineer and as a person.
I've always believed that everyone can help change the world, and with technology improving exponentially, I would like to do my part by finding ways to help overcome some of the challenges people face.

Senior Design Project
Air Source Heat Pump with Pulse Electrothermal Deicing (PETD)
For my senior design project, our team spent 6 months developing and testing a pulse electrothermal deicing (PETD) system to improve air source heat pump (ASHP) performance in cold climates. The goal was to reduce inefficiencies caused by frost buildup by integrating PETD technology to melt ice without interrupting heating cycles. We designed triac based switching circuits, custom coils, and transformer systems to deliver high power pulses safely under real icing conditions. Testing showed that our PETD integrated ASHP reduced defrosting energy use by up to 39% compared to the industry standard!
