I'm Yougi — an Informatics & Psychology student at UMass Amherst building dashboards, models, and data pipelines, including a live NYC collisions app over 27K records.
I work at the intersection of data and human behavior — pairing technical analysis with a psychology background to ask better questions of the numbers.
Currently pursuing a B.S. in Informatics & Psychology at the University of Massachusetts Amherst (expected May 2027). My projects span the full pipeline: building datasets, writing SQL, training models, and shipping dashboards that non-technical stakeholders can actually use.
A public Streamlit app analyzing 27,164 NYC collisions (Jan 2020 – May 2025) — 13,508 injuries and 64 fatalities across all five boroughs. Four SQL analyses (severity, borough, hour-of-day, monthly trends) sit on a validated 23-field schema, with caching and pytest/CI for fast, reliable loads.
An end-to-end R report flagging at-risk customers across 10,000 records and 14 features. Logistic regression vs. Random Forest under 5-fold cross-validation, handling a 20.4% churn class imbalance, with decision thresholds tied to retention strategy.
Selected for Purdue's Market Readiness Incubator. As project manager, I designed the analytics-ready PostgreSQL (Supabase) backend — a relational schema with SQL CRUD plus multi-field search, sorting, and pagination, backed by integrity checks.
Spiritual Data · Remote
Built a benchmarking harness comparing a proprietary model against baselines on 3+ metrics, designed evaluation splits and error slices to surface failure modes, and produced a stakeholder evaluation report aligned to business and compliance needs.

Cleaned and prepared survey data from 700+ participants into analysis-ready datasets, then ran quantitative analysis (EDA, regression) on how social media use relates to public attitudes.
B.S. Informatics & Psychology — Double Major
A double major bridging data and human behavior — informatics for the technical foundation (programming, databases, analysis) and psychology for the research methods and statistics behind asking sharper questions of the numbers.
Open to data science and analytics roles, internships, and collaborations.
