Daniel Zeltser / BME + CS at Duke
I build products at the intersection of healthcare, AI, and operations.
Studying Biomedical Engineering and Computer Science at Duke University
What started as curiosity about cryptocurrency quickly became an exercise in hardware, economics, and operations. I built mining rigs from individual components, optimized performance and power consumption, and expanded into a small-scale mining operation.
Inspired by my grandfather's Parkinson's disease, I developed a haptic feedback application designed to assist patients through wearable sensory cues. The project introduced me to biomedical engineering, human-centered design, and the challenge of building technology for healthcare.
After spending a summer in Uganda, I partnered with Makerere University to develop BiliBright, a low-cost handheld device aimed at improving neonatal jaundice screening in resource-constrained environments. The project was recognized in the Africa Business Concept Challenge and deepened my interest in global health innovation.
With no finance background and surrounded by peers recruiting for investment banking, I built Kwolify to organize outreach, networking, preparation, and recruiting workflows. The platform helped me secure an elite boutique investment banking offer and is now used by many of my friends navigating the same process.
Layra grew out of automation built inside a real rheumatology practice, from patient records and lab analysis to charting, payment posting, and denial tracking. The company is building AI agents for medical billing and back-office healthcare operations.
