Hi there—thanks for dropping in.
I'm Aiden Wan, currently a data science graduate student at UCI.
and what you're seeing is my data stories pressed to vinyl.
Put the record on and follow the grooves;
each track shows how I turn raw data into insights you can feel.
Let's spin!
[Side A: internships]
Side A is the radio cut: internship singles where I learned to turn messy numbers into clear business wins. You can find all the full details in my resume!
My latest internship, where I worked across user segmentation, causal inference, ETL pipeline development, and predictive modeling — helping the team uncover insights, streamline data, and make smarter decisions.
Probably my favorite experience — I built strategies and models for content moderation, helping shape a sincere, welcoming, and safe community for users.
My very first internship. I designed A/B tests, built visualization dashboards, and applied machine learning to e-commerce data, helping drive new feature launches and fuel revenue growth.
[Side B: original projects]
Flip to Side B for the unreleased B-sides — passion projects you've probably never seen before!
For my best friend's birthday, I built a time machine: every morning in 2025, they receive a personalized "on-this-day" email, recapping everything we texted on that date over the past four years.

Film Emotion Analyzer turns any subtitle file into an interactive emotional arc: it scores each line with transformer embeddings, applies Gaussian smoothing per act, and adds hover tooltips for key moments—transforming raw dialogue into a cinematic journey.

Need one more spin? Side C holds the remixes and collabs like kaggle competitions.
This collaborative Kaggle project builds a two-stage recommender for OTTO: session co-visitation for candidate generation, followed by XGBoost reranking on temporal, behavioral, and popularity features—predicting the most likely items for clicks, cart additions, and purchases.

I'm Aiden Wan — someone who loves working with data, and building systems where precision meets emotion.
This portfolio is inspired by BRAT, my favorite album of 2024 — an album where delicate, vulnerable lyrics live inside sharp, technical dance production. I loved how something so mechanical could still carry so much feeling — and it made me think: why can't data do the same?
Every experience here follows that idea: balancing technical depth with human resonance. Whether it's my internships or the gift I built for a friend, each project aims to connect — not just operate.
Outside of data, I'm a music and film lover. I believe storytelling — whether through sound, image, or system design — is what truly brings people together.
Thanks for stopping by!
