Building predictive systems and scalable pipelines that transform complex data into decisive action.

01About

ABOUT ME

I build intelligent systems that turn messy data into clear decisions. With an M.S. in Data Science from Vanderbilt, I bring a Mechanical Engineering foundation that taught me to think in systems: tolerances, constraints, and trade-offs. Now I apply that rigor to machine learning pipelines, scalable architectures, and production AI.

My recent work spans industry and academia. At SERVPRO, I built a GPT-4 Vision agent that automates BI reporting for 13,500+ job records nightly, eliminating 40+ hours of manual work. At Nissan, I led a team that analyzed 140,000+ training logs and built a RAG-based chatbot presented to NA executives. In research, I achieved 98% accuracy on AI-generated image detection using deep learning.

Right now, I'm most energized by Generative AI, computer vision, and the craft of turning complex systems into intuitive experiences. When I'm not shipping code, you'll find me exploring the latest AI tooling, immersed in story-driven games, or watching WWE.

Work Experience

Data Science Intern

SERVPRO

Aug 2025 – PresentLebanon, TN
  • Developed a Vision-Based Automation System using GPT-4 Vision to autonomously navigate legacy portals; engineered spatial reasoning logic to visually detect and bypass dynamic pop-ups, achieving 99% reliability.
  • Engineered an end-to-end BI automation pipeline processing 13,500+ job records nightly, orchestrating Playwright web scraping and Microsoft Graph API distribution—eliminating 40+ hours of manual weekly reporting.
  • Engineered a Python-based transformation layer (Pandas) to process raw logs into complex financial models; programmatically generated 11 pivot tables and multi-tier AR aging reports.
  • Deployed a GitHub Actions CI/CD pipeline with daily CRON execution, Azure AD OAuth 2.0 authentication, and secure secrets management, achieving 100% hands-free operation.

AI Intern (LDP)

Vanderbilt University

Jun 2025 – Aug 2025Nashville, TN
  • Built a secure web app to automate coach-student matching for the LDP, cutting manual work from days to under 10 minutes.
  • Designed an anonymized data pipeline integrating resumes, surveys and bios to generate coach matches and rationale via OpenAI API.
  • Delivered a five-column Excel output with ID-based top-2 coach matches and reasoning, enhancing transparency & scalability.
  • Developed an embedded AI assistant with safety guardrails, refusal logic and prompt evaluation to support business students.
