About

Building things that matter.

I'm a physics grad from Union College who writes software, runs experiments, and turns complex ideas into working code. My work spans AI/ML engineering, computational physics, and quantum computing.

My senior thesis tackled finite-difference quantum eigenvalue problems. I've also built ML pipelines for computer vision, created physics simulations and visualizations, and earned three IBM Quantum credentials.

Currently: AI/ML Software Engineering Intern at NextDimension AI, building voice AI and intelligent automation for healthcare.

Now

What I'm building

A snapshot of what I'm actively working on, exploring, and thinking about right now.

🤖 Active

Voice AI for Healthcare

Building AI-powered voice and text agents at NextDimension AI that handle patient requests 24/7. Working on the full pipeline — NLP, intent recognition, workflow orchestration, and the AI+Human handoff layer.

Quantum Error Correction

Deep-diving into hardware-efficient quantum error correction via concatenated bosonic qubits. Following the latest research out of Google and IBM on making fault-tolerant quantum computing practical.

🧠 Learning

LLM Application Engineering

Going beyond prompt engineering into building production LLM systems — RAG pipelines, tool-use patterns, evaluation frameworks, and agentic architectures. Applying this directly in the work at NextDimension.

🔭 Exploring

Post-Thesis: Extending the FD Work

Looking at where to take the finite-difference quantum solver next — potentially extending to 2D/3D systems, time-dependent problems, or scattering states. Thinking about what makes a good follow-on project.
