About me

I work in machine learning, primarily in the recommendations space. A lot of my work focuses on the personalization of items from high-cardinality catalogues over millions of users. The associated engineering challenges of scaling and maintaining these online systems have formed the mainstay of my career over the last several years.

Various writings

This site exists primarily to document my thoughts about mathematics, machine learning, and data engineering. My hope is that these musings and treatises can also serve as a valuable pedagogical tool for other ML practitioners.

Pedagogical expositions

  • Axiomatic motivation of calculus
  • Machine learning from scratch
  • Practical lessons in ML
  • Some solution sketches

I also track my progress with my hobbies and interests on some associated blogs.
