Software Engineer · AI Engineer
I build production software and agentic systems — currently working on healthcare infrastructure at Epic Systems, and exploring multi-agent reasoning, RAG/MCP pipelines, and using AI to automate complex workflows.
Experience
Software Developer
Epic Systems · Verona, WI
Jan 2026 – Present
- Engineered an opt-in filing model and pop-up interface to prevent surgical history clutter for hundreds of surgeons; grouped redundant procedures and enabled discretionary filing to conserve thousands of postoperative hours across 15+ hospitals.
- Cut data entry latency for 500+ healthcare networks by architecting a React, C#, and TypeScript interface; reconciled legacy data to assist nurses in populating missing vendor fields, streamlining supply-chain workflows and eliminating supply waste.
Software Engineer (AI/ML)
PaperScore · Austin, TX
Sept 2025 – Dec 2025
- Architected a multi-agentic evaluation pipeline utilizing RAG and MCP to autonomously determine manuscript novelty.
- Scaled data ingestion 30× by developing an agentic web scraper (Browser Use) capable of indexing 30+ journals per hour.
- Boosted reliability from 25% to 80% by refactoring the C# backend with semaphores and rate-limiting to manage API traffic.
Computer Vision Research Assistant
MadAbility Research Group · Madison, WI
Jun 2024 – May 2025
- Architected a real-time computer vision pipeline utilizing YOLOv8 for sub-second object detection (faucets, sinks) to trigger restrictive visual augmentations for in-site OCD self-management and compulsion disengagement.
- Outperformed COCO accuracy by 15% by curating a dataset of 1,250+ images and fine-tuning a YOLOv8 model in PyTorch.
- Improved clinical intervention success by 60% by designing an AI-driven AR system in Unity/C# that integrated Exposure and Response Prevention (ERP) and Acceptance and Commitment Therapy strategies into real-time patient environments.

Projects
News Trader
Verona, WIBuilt a high-throughput Python Asyncio engine processing 5k+ daily signals using task queues. Engineered a multi-agentic "council" using various LLMs to autonomously classify geopolitical and corporate events — achieved a 160% return on paper-traded capital over a 1-month validation period during the war in Iran.
Smart Stock
Madison, WIFull-stack Java/Spring Boot inventory system with a RESTful API handling concurrent inventory updates. Hardened security via Spring Security role-based access control and containerized application services with Docker.
Outlier
Scaled a full-stack word puzzle platform to 100+ active users with a responsive React/TypeScript frontend. Eliminated 100% of manual content operations by architecting an autonomous pipeline using Gemini API and GitHub Actions — generating and deploying daily puzzles of varying difficulty, reducing operational overhead by 20+ hours/week.
Neural Machine Translator
Hong Kong S.A.R.Achieved a 4× improvement in BLEU scores by fine-tuning a pre-trained BART transformer using Hugging Face. Accelerated model training cycles by 40% by engineering a high-concurrency PyTorch pipeline with custom tokenization.

Beyond Code
A few things I care about outside of work.
Volleyball
Volleyball has been a big part of my life — I play competitively and love the team dynamics, quick decision-making, and the grind of improving every rep. Whether it's pickup games or organized leagues, you can usually find me on the court on weekends.
Currently Learning
In my free time I'm deep-diving into multi-agent thinking — how to design systems where multiple AI agents reason, debate, and collaborate to solve problems no single model can. I'm also experimenting with using Claude to control my computer, building real workflows where Claude writes code, runs tools, and ships things end-to-end with minimal human input.
YouTube
I put project demos and build videos on YouTube. Check out my Smart Stock inventory system demo — a full walkthrough of a production-grade Spring Boot + React app with Docker and Spring Security.
