Hi, I’m Archit. I’m an ML engineer with 13 years across ad tech, e-commerce search, and recommender systems at Meta, Walmart, and Adobe. I learn by reading, but I only really understand something once I write it down — this site is where that happens. The notes are terse and written for my own revision, on ML design, ML infra, and occasionally how I think about work and time.
