What you get
Everything you need to build employer-ready skills, live, every week.
10+ sessions a month
New live masterclasses every week, taught by working practitioners, not narrators.
Moderated Q&A
Ask questions live in every session and get answers from the person who does this work.
30-day replays
Miss one live? Every session is recorded and yours to rewatch for 30 days.
Posit Workbench included
A fully provisioned professional environment in one click: Positron IDE, AI assistant, cloud compute. Nothing to install.
Career development sessions
Monthly portfolio development, simulated technical interviews, and take-home test practice, led by the founder.
Projects you can ship
Build things you can show an employer, using current tools and real data. Sports is our classroom.
Four AI-assisted tracks
Every masterclass belongs to a track, so your live hours add up to a coherent skillset. AI is the accelerator, not the answers.
Modeling & Methods
Bayesian modeling with PyMC, resampling and permutation tests, regularized regression, missing data. The statistical core, taught by the people who wrote the tools.
App Development
Interactive data viz in R, Shiny and Streamlit apps, tables and reporting. Turn analysis into software someone else can use.
LLM Tools
Choosing and evaluating LLM models, natural language data queries, unstructured text to tidy data. Build with LLMs instead of just prompting them.
Production
APIs and pipelines, from scripts to packages, automation with GitHub Actions, fast data wrangling at scale. The skills that make work shippable.
The career layer
Not a footnote. Alongside the tracks, every member gets founder-led career development sessions each month.
Portfolio development
A monthly working session on the portfolio itself: what to build, how to present it, and how to defend every decision in it.
Simulated technical interviews
Structured mock interviews on the material in your track, with direct feedback, so the real one is not your first rep.
Take-home test practice
Timed, realistic take-home exercises like the ones data teams actually send, reviewed so you know where you stand.
Led by Michael S. Czahor, PhD, founder of AthlyticZ, after 7+ years of MLB front-office R&D.
