ABOUT ME
Jack of all trades, master of none
Jack of all trades, master of none

Apache Spark committer and Databricks Beacon.

Other than that, just a dog on the Internet. I would love to tell you more, but then, of course, I'd have to erase your memory.

Note

I am not taking any new commercial requests at the moment, however I am happy to volunteer my services to non-profit or research institutions

Fees

Fee for short-term requests from business clients is non-negotiable with exception to cases described below. If you are looking for long-term help please consider posting an offer on Arc, which among other benefits, provides a favorable platform fee structure.

If you represent a non-profit organization, academic entity or you are an individual interested in long-term mentorship please contact me directly so we can discuss your requirements and eventual discount.

If I respond to your requests or add request notes, it usually means that I accept suggested rate and already applied discount. Please check the fee visible to you in the chat window to confirm that.

Guarantees

Due to the nature of live sessions (lack of formal specification, possible technical and communication issues), a satisfying resolution of the problem is not always possible, therefore I offer a 100% satisfaction guarantee. If for some reason you are not satisfied with an outcome of the particular session please provide me with the feedback and request a refund before we disconnect and I will issue it promptly after the session is finished.

Non-Disclosure Agreements

TL;DR I won't sign your NDA, and if you start a conversation by sending one, I won't respond.

To not to reiterate things which have been said more eloquently multiple times please take a look at the Entrepreneurs vs. Freelancers vs. VCs section of the Codementor Essential Guide to NDAs (https://tinyurl.com/entrepreneurs-vs-freelancers) for the explanation.

Academic integrity

Please don't ask me to be involved in activities which would violate your academic integrity, like completing graded assignments, writing research papers or thesis. Also please note that requests like this are explicitly forbidden by the Codementor Terms of Service (https://www.codementor.io/terms).

I am happy to help you with projects explicitly allowing external collaboration (as long as it can be confirmed using publicly available syllabus of comparable source), reviews and overall mentorship and guidance.

I am also a huge enthusiast for lifelong learning. Don't hesitate to contact me if you're looking for support and study help (in boundaries of applicable Honor Code) when taking publicly available online courses in topics related to general programming, machine learning, and computational biology.

Maciej is just the best. Even before I was done explaining the issue with my code, he already had a deep understanding of what was going wrong. His explanations are clear and concise. I will use him again and highly recommend him.

In my most recent session with Maciej, he took a problem I had been struggling with and broke it down into a format that had a clear direction. He exposed me to new tools and methods and designed a tractable solution. He is a great teaching and is a pleasure to work with.

Truly a wonderful mentor! Actually cared & wanted to make sure I understood how to solve the problem on my own. Instead of just giving me the answer, he asked me questions to get my brain thinking & see if I could generate the answer on my own.
