Data Science Tutors face unique challenges: Half of a beginner session evaporates fixing their Python environment and library versions before any actual statistics happen. Students range from a humanities grad learning a for-loop to a working analyst tuning XGBoost, so prep almost never carries over. Capstone and thesis students need code-and-results review between sessions on their notebooks, and that debugging time falls outside the booked hour. Bootcamp-to-job students cram hard around interview dates, then go quiet after landing the role with no referral or testimonial captured. On top of all that, FreshBooks charges $43/month ($516/year) — money that comes directly from your revenue. The median Data Science Tutor earns $42,000/year. Software at $516/year is a meaningful percentage of that income, every year, forever. And you do not own anything.
Your Jupyter notebooks and the Python pandas / scikit-learn stack is yours. You bought it once. Nexa works the same way — $279 once for invoicing, scheduling, CRM, time tracking, and full accounting. All connected. All offline-capable. You own it like you own your tools.

The first twenty minutes of a beginner session are almost always a sacrifice to the environment gods. A student's pandas import is throwing an error because her numpy is the wrong version, so before we touch a single concept I am rebuilding her Anaconda environment over screen share. Once it runs, the real lesson begins, and today it is the difference between a list and a Series, the thing that quietly trips up everyone coming from spreadsheets. My next student is a working analyst, a different planet entirely; we are tuning an XGBoost model and arguing about whether her cross-validation is leaking data from the test fold, the kind of mistake that looks like brilliant accuracy and is actually a bug. Midday I review a master's student's thesis notebook, leaving comments on her feature engineering and one chart that overstates her result, work that happens between our sessions and outside the hour. Afternoon is interview prep, drilling a career-changer on the bias-variance tradeoff and why his model overfits, the questions hiring panels love. I sketch matrix shapes on the tablet because half of debugging machine learning is just keeping the dimensions straight in your head. The ones who get hired tend to vanish, and I rarely think to ask the grateful ones for a testimonial.
