At the heart of my academic and engineering work in machine learning is a passion for finding optimal solutions for complex problems.

After managing an in-house research department, earning my PhD in machine learning and launching a startup, I saw an opportunity to apply my knowledge to the costly and time-consuming data-related challenges businesses face today.

After freelancing for a few years, I became frustrated by the sorry state of the industry, with many consultants re-selling ineffective, pre-packaged software to every client. I also saw a growing rift between academic research and what was being practiced in the field.

I believed businesses deserved a better option, and RaRe was founded on that belief. I am proud to have assembled a team capable of merging theory and practice to build pragmatic solutions that are better by design.
