Fedor N.

Data Scientist | ML/AI, Quant Finance, Operations Research

I hold a PhD in Applied Mathematics and an MSc in Computer Science, with around 10 peer-reviewed papers published. For around 20 years, I've applied my academic knowledge and engineering skills to problems in machine learning, quantitative finance, and operations research. Most developers can implement a model. Fewer can tell you why it works, when it will break, and how to validate it before it touches production or real capital. That's the gap I fill — academic-level rigor combined with the engineering skill to actually ship it. I'm a confident, hands-on programmer in Python and C++ — Python for research, modeling, and fast iteration; C++ when performance, memory footprint, or production stability can't be compromised. I've also worked extensively in Java and Rust. I've worked inside large enterprises, inside early-stage startups, and independently as a consultant — so I'm equally comfortable plugging into an established process or running a project end to end on my own. I'm happy to discuss your project and figure out the best way to help — feel free to reach out.
