Available for Summer 2027 internships

I turn messy product data into decisions a team can defend. Economics gives me the question worth asking; data science gives me the evidence. Most recently a product analyst intern at MobilityWare, working on the live-ops analytics behind a mobile games portfolio.

Profile

I am a progressive-degree student at the University of Southern California, finishing a B.S. in Economics and Data Science in 2027 and continuing directly into the M.S. in 2028. I hold a 4.00 and a Presidential Scholarship, the university's award for outstanding academic achievement.

The two halves of the degree do different jobs. Econometrics trains you to distrust a correlation until it has earned its keep; machine learning gives you something worth building once it has. In practice that means I am comfortable both defending a causal claim and shipping the model that acts on it.

What I want next is a summer 2027 internship where the analysis actually changes what gets built — product analytics, data science, or quantitative research, on a team that argues from evidence.

Experience

  1. MobilityWare

    Jun – Aug 2026

    Irvine, CA

    Product Analyst Intern

    • Partnered with product and design on live-ops experiments across a mobile games portfolio, turning player telemetry into recommendations the team could act on within the week.
    • Built and maintained SQL queries and dashboards for engagement, retention, and monetisation, so decisions started from one shared set of numbers instead of competing spreadsheets.
    • Wrote analyses for non-technical stakeholders: what moved, how much of it we could actually attribute, and what to do next.
  2. USC Garden Club

    Sep 2024 – May 2026

    Los Angeles, CA

    Treasurer

    • Led the annual fundraiser and doubled fundraising revenue year over year.
    • Allocated the budget across club operations and kept records accurate enough that any member could check them.
    • Planned community-building events with the rest of the board.

  • Boston Consulting Group

    GenAI Consulting · Aug 2025

    Cleaned and analysed large-scale financial data in Python and pandas; interpreted 10-K and 10-Q filings, delivering readable insight through a chatbot interface.

  • Electronic Arts

    Product Management · Aug 2025

    Identified the KPIs that genuinely measured a messy business problem, and synthesised recommendations for video game product strategy.

  • Commonwealth Bank

    Data Science · Aug 2025

    Engineered data pipelines, implemented anonymisation to keep personal data compliant, and recommended database structures for social media analytics.

Selected work

Steam Games Performance Visualizer & MLP Regressor

Nov 2025

An end-to-end study of the Steam catalogue: clean a hundred thousand rows, work out what actually predicts a game's performance, then let someone put a question to the model in plain terms and get an answer back with the chart that supports it.

  • Processed and modelled a 100k-row dataset spanning 1,260+ unique games in pandas and Matplotlib — normalisation, categorical encoding, and outlier handling included.
  • Designed interactive, accessible dashboards surfacing the performance signals that matter for game analytics, so evaluation rested on evidence rather than instinct.
  • Developed branching logic driven by qualitative metric analysis to train targeted scikit-learn MLP regression models against user-defined queries, holding R² above 0.50 across every model.

I rebuilt the modelling side of this as something you can actually run. The sandbox trains a multilayer perceptron in your browser — written from scratch in JavaScript, no libraries — and races it against a linear regression on the same data, so you can see where the extra machinery earns its place and where it does not. Held-out R², a live loss curve, and permutation feature importances are all computed as it trains.

Why your A/B test is lying to you

Almost every experiment dashboard updates daily, and almost everyone watching one has stopped a test the moment it turned green. This simulates thousands of experiments between two identical variants and measures what that habit costs: checking once at the end holds the false positive rate at the 5% you paid for, while peeking daily pushes it past 20%. It also shows the quieter half of the problem — stopping early selects for runs that got lucky, so the effect size you report comes out inflated.

Cohort retention & LTV explorer

The instrument panel a consumer or games business actually runs on. Six levers drive a retention curve, the cohort triangle it implies, lifetime value against acquisition cost, and where DAU settles once the funnel reaches steady state. The uncomfortable arithmetic it makes visible: a product can look healthy on every headline metric while each install quietly loses money — and scaling spend only loses it faster.
