Researcher at RelationalAI

May 2017 - Aug 2018

Jamie is a first principles thinker with a deep understanding of systems and algorithms. He is fearless in the way he approaches problems. Jamie’s research on staged compilation saved our team many person years of effort, and his training and support was crucial to our adoption of Julia. I hope to have the opportunity to work with him again soon.

RelationalAI is building a relational database, a probabilistic programming language and various integrated machine learning systems. I took on the task of figuring out how to make this project feasible, given the small size of the team and the limited funding time-frame.

I built several prototypes in Julia, demonstrating better performance than existing work with much less implementation effort. To allay concerns about adopting Julia, I:

As a result RelationalAI adopted Julia for all ongoing development, after which I:

Jamie brought a degree of rigor and theoretical knowledge that took the company to places we never could have gone otherwise. From exploring the implications of language semantics to building high performance database engines, he didn’t just help us get things done, he helped us get them done right. As a result, we were able to explore in weeks what could’ve easily taken years

Jamie took over the latexsearch engine, our most technically challenging project to date, and turned it from a foundering prototype into a successful service with over 200k users. His engine required only one small server and ran uninterrupted for over 5 years with no errors.
