Turning messy data into clear answers with Python, SQL, and Tableau. I build real open-source tools and ship working software.
A complete browser-based prep suite for breaking into data analytics, sequenced in the order an analyst actually learns: Excel → SQL → Python → Tableau → Stats → Power BI → Interview, plus a week-1 job simulator and a cross-subject final exam. Read-it-aloud code breakdowns, live in-browser practice environments, AI manager review on the simulator. No install, no login, no telemetry.
Learn SQL by catching a CFO embezzling $1.87M. Write real queries against a live database — no slides, no exercises, every query is evidence. Two full seasons of SQL objectives, a cartoon cel-shaded terminal, and concept cards that unlock as you investigate.
Generate realistic test documents and data files in seconds — invoices, contracts, SOPs, messy spreadsheets. Fully offline. No real customer data. Free Windows installer, no Python needed.
A data-cleaning and auditing tool: it profiles a messy spreadsheet, flags data-quality issues, applies automated fixes with a full change log, and ships with a desktop GUI.
Early-career data analyst pursuing Tableau certification and building with Python, SQL, and pandas. Strong research and training background — I find the signal in messy data and explain it clearly.
I build real open-source tools using spec-driven development. The Analyst Prep Kit is a nine-module browser-based learning suite (Excel, SQL, Python, Tableau, Stats, Power BI, Interview, a week-1 job simulator with AI manager review, and a cross-subject final exam). Alongside it: a data-gen desktop tool and a spreadsheet auditor. I learn fast and I ship working software.
