Data Science @ Metropolitan State University | GPA: 3.9 | Two-Time 1st Place State Winner | Building Multi-Agent Systems & CV Pipelines to Bridge Systemic Gaps

I am a Data Science student driven by a single mission: Finding the "blind spots" in our systems and building the technical bridges to fix them. Whether itโ€™s healthcare access, financial equity, or career transitions, I use data to ensure underserved groups aren't left behind.


๐ŸŽ–๏ธ Competitive Benchmarks & Honors

  • 1st Place Team Winner โ€“ HeatMap Hackathon (03/2026): Ranked #1 in the state for identifying geographic disparities in U.S. burn care access. Managed the technical GitHub repository and ensured project integrity through data-driven storytelling.
  • 1st Place Winner โ€“ Minnesota AGENT.AI Competition (10/2025). Ranked #1 in the state for predictive accuracy and technical logic in retail banking fraud detection.
  • Deanโ€™s List & Scholarship Recipient โ€“ Recognized for consistent academic excellence.

๐Ÿ† Outstanding Projects

  • AgentDS-Retail-Banking-Fraud: The real-world data and domain knowledge & logic and Python pipeline behind the 1st Place MN AGENT.AI win.
  • HeatMap-Burn-Care-Access): Collaborative Hackathon project. I developed interactive mapping and data synthesis to identify gaps in healthcare services.
  • Developer-Skills-Analysis: IBM Capstone. Engineered a pipeline for 70k+ records to bridge the gap between education and market demand.
  • ai-form-analysis: 3-Month Technical Roadmap: Built OpenCV + MediaPipe pipelines for pose detection and frame sampling from MP4 data. Extracted joint angles and stored annotated frames with summary data.Developed biomechanical analysis across 5 throw phases โ€” compared joint angles against elite athlete profiles (flagging >15ยฐ deviations), estimated hip/wrist rotational velocity, and integrated Gemma vision models to generate structured coaching reports.,Shipped a Streamlit web app combining the full pipeline into a single interface. Users upload video and receive pose overlays, velocity metrics, and AI coaching feedback โ€” running entirely locally via Ollama (no API costs, no internet required).

๐Ÿ† Featured Projects (The "Bridges")

๐Ÿงฌ Burn-Care-Equity-ROI-Analysis (The "Engine" behind the 1st Place Win)

While the broader team focused on the Composite Vulnerability Index (CVI) presentation, this work provides the underlying financial and geospatial engine โ€” quantifying state-level avoidable hospitalization costs from burn under-referral, scoring 498+ trauma centers as telemedicine hub candidates, and mapping population-weighted distance burdens using Census and NIRD 2023 data.

  • Economic Insight: Modeled avoidable hospitalization costs from burn under-referral at the state level using Murray et al. (2019) excess LOS data ($3,500/day) and Huang et al. (2021) 66% under-referral rate, producing state-by-state cost burden estimates from the NIRD 2023 database.
  • Innovation: Engineered a "Tele-Burn Hub" opportunity scoring system ranking non-burn trauma centers by referral gap potential, factoring in trauma level, bed capacity, and burn care absence โ€” mapped geographically using Folium.
  • Impact: Identified high-priority telemedicine spoke candidates (opportunity score โ‰ฅ 5) across states with the greatest access-to-quality gaps, with projected reductions in excess hospitalization days and avoidable costs.
  • Tech: Python, Folium Geospatial Mapping, ROI Modeling

๐Ÿ”ฎ Future Research & Project

  • [Resource-Hub]: "Humanity First" system .

๐Ÿ“š Learning Corner: Continuous Upskilling

I maintain a structured "Just-in-Time" learning library to bridge the gap between academic theory and industry-grade execution.

๐Ÿค– Agentic AI & LLM Orchestration

Focus: Mastering autonomous systems and prompt engineering.

๐Ÿ“Š Data Engineering & Analytics Infrastructure

Focus: Scaling pipelines and professional visualization.

๐Ÿง  Deep Learning & Math Foundations

Focus: Understanding the "why" behind the models.
