Data & Business Analyst

I read the data.
It tells me things.

โ˜…โ˜…โ˜…โ˜…โ˜… โ€” Former tarot reader, current data reader

Currently in product operations, I sit where business and data meet โ€” turning Jira backlogs, sprint work, and messy ticket data into the insights and process improvements that help teams make better decisions. I work fluently across SQL, Python, and Tableau, partner closely with product managers on prioritization, and use AI-assisted tools to move faster โ€” so more of my time goes to what actually matters: asking the right questions and telling the story the data is trying to tell.

Jira Microsoft Excel Pivot Tables Process Analysis Synthetic Data
Reading a Messy Ticket Queue

A methodology walkthrough on a synthetic ticket queue I built from scratch โ€” a demonstration of how a product operations analyst turns a messy backlog into insight. Using a Jira-style export, Excel cleanup, and pivot tables, I work through volume trends, category shifts, and a subtle finding buried in the priority field. Built on invented data; the focus is the process, not any real company.

01 Methodology Walkthrough
โฌก The Wheel of Fortune
PostgreSQL Docker Tableau Python SQL
Yu-Gi-Oh! World Championship Database

Started with a question: which regions and deck archetypes actually dominated 21 years of competition, and how did the meta shift over time? To answer it I designed a normalized PostgreSQL database (18 championships, 36 players, 26 archetypes), wrote the SQL to surface the trends, and visualized them in Tableau โ€” with Docker for a reproducible setup. Swap "decks" for products and "regions" for markets, and it's the same competitive-performance analysis a business runs on its own data.

02 Database & Analysis
โฌก The Moon
Python Pandas Matplotlib Seaborn Jupyter
Goodreads Book Dashboard

I treated my own reading history (485 books) as a dataset a stakeholder might care about, then asked what's actually worth knowing: what drives a high rating, how habits shift over time, where the patterns break. Built in a Jupyter notebook with Pandas and 9+ visualizations โ€” but the real exercise was turning a vague "what's going on here?" into specific, answerable questions, and presenting the answers so a non-technical reader gets them at a glance.

03 EDA & Visualization
โฌก The Empress
Tableau Public Microsoft Excel Data Visualization Data Cleaning
Yu-Gi-Oh! TCG Market Analysis Dashboard

A market-analysis dashboard treating a collectibles market like any other product market: what's appreciating, what's losing value, and where popularity and price diverge. Using Tableau and Excel on 2020โ€“2026 data, I tracked price trends, estimated unit sales, and collector-value gaps โ€” the same demand, pricing, and segment-performance questions an analyst asks of any business. Cleaning messy real-world data into something decision-ready was half the work.
