Calling sklearn or PyTorch APIs and using pretrained models seems easy, but digging in to develop a deeper understanding of how methods work, when to apply them, and how to push their limits can be daunting and confusing.

Having gone from research to industry, I have successfully guided interns, bachelor/master graduates, and Ph.D. students on their path through the field of machine learning from concepts to applications and back.

Currently, I work as co-founder and principal engineer at an early-stage machine learning start-up coming out of my colleagues and my academic research. I am also very happy to talk about product-market-fit, validation, business models, start-up fundraising and bootstrapping, and all the things related to the pre-seed/seed stage.

Prior to starting my company, I worked as a machine-learning research scientist bringing deep learning methods on tabular data to know-your-customer and anti-money-laundering products in financial institutions.

Before that, I completed my PhD where I developed machine-learning algorithms for reverse engineering software and applied them on software engineering and network analysis tasks.

Throughout my career, I've done commercial data science consulting projects on the side.

5 out of 5 stars

Chris is an excellent mentor! He is very knowledgeable and is able to explain complex concepts in a way that is easy to understand. He is also very patient and is always willing to answer any questions I have. I would highly recommend Chris to anyone looking for a machine learning mentor!



5 out of 5 stars

Chris has been a great mentor to work with! Before starting, I already worked as a data scientist, but was looking to deepen my understanding, create a continuous learning practice for myself, and be more confident in the enormous field of ML/DL. Chris really excelled at providing accountability, being a sounding board to create that practice, and in helping create more confidence in myself about the deeply technical parts of ML/DL. We started by outlining areas of ML that I would want to expand my knowledge in and Chris helped encourage me to write up my readings in each subfield and ultimately helped create a practice of reading papers and really internalizing what was being communicated. Once I became more confident in engaging with literature, I began to want to explore the practice of research. I came up with a problem and Chris acted as a great sounding board and mentor in this capacity to focus my idea. He lent his expertise in academia to help me understand how to progress on my ideas and I'm now working towards publishing my work. I really can't thank Chris enough for his help and mentorship over this journey. While I'm sure Chris could help anyone just starting out, I also think he would be a perfect fit for anyone who's already in the field, but is looking to go a lot deeper in their understanding and broaden their perspective on the field as a whole.

Chris is an amazing mentor who goes above and beyond in providing feedback, tips, and useful learning material. I came to Chris for help on a classification project, and he gave me extremely thoughtful tips and guidance on how to best approach it. Chris is also very responsive and easy to work with, I would highly recommend!
