Mentoring

Data science mentoring with Boris Gorelik: for teams without a senior data scientist, for companies not sure they're ready for data science, and for people deciding on a data career.

Building data-based models since 2001. Mentoring since 2013.

Mentoring is for when you need a senior data person for a few hours a month, not a hire. Three situations where it works.

You either can’t or don’t want to hire a senior data scientist

You have a junior data scientist, or a software engineer who got the data job by default, and nobody senior to look over their shoulder. I’ve been that senior person for biotech, fintech, and green-tech companies: reviewing models before they ship, setting coding and visualization standards, and helping decide which problem to work on first. Your person does the work. I make sure it’s the right work, done right.

You are not sure your organization is ready for data science

Most aren’t yet, and that’s fine. Before you hire anyone, we look at what data you have, what decisions it could change, and whether a spreadsheet would do the job. Sometimes the answer is “not now”. I’ve guided teams moving from pure software to data-driven development, and the hard part is rarely the algorithm. (It’s the data. It’s almost always the data.)

You are not sure what to do with your career

Should you study data science? Switch into it? Out of it? I’ve been asked this enough times to write it down. Start with Don’t study data science as a career move; you’ll waste your time! and the rest of the career advice posts. If your question isn’t answered there, book a call.


At first, I was a little lost with the frame of the project, but you helped me set up guidelines so that I could start to work on the project quickly and efficiently. Whenever I had a question, I felt that I could ping and you to get answers.

How it works

  1. A free intro call, no obligation. Book it here.
  2. We decide together what you need. Some problems take one conversation. Some take an hour a week for a few months.
  3. Founders who want product and tech strategy rather than data mentoring: that’s a different service.
