Hello, World!

I'm Ivan, developer and data scientist

I'm a Machine Learning specialist, and I use those skills to build analytics solutions for venture capital and portfolio companies as an individual contributor. On the side, I'm pursuing a Master's in Computer Science with an ML focus. These days I'm drawn to fluid interfaces for AI systems and design in general, and completing long runs by the lake.
