Profile: https://flows.cv/adityas2

I am an ML architect who enjoys getting their hands dirty with both theoretical complexities and practical implementations. Over the past decade, I've architected, built, and deployed ML systems that have touched millions of users - from helping Walmart understand that "blue thingy" might actually be a cobalt ceramic vase, to teaching Pinterest's algorithms learn users' shopping intent, to showing Meta's ads system that sometimes less is more.

My debugging sessions often start with linear algebra and end with distributed systems traces (and sometimes vice versa). When I'm not doing that, I'm probably explaining to my espresso machine why it needs better hyperparameters for optimal brewing temperature. So far, it remains unconvinced.

Technical specialties:

End-to-end ML System Architecture & Implementation
Search & Discovery Systems
Large Language Models & GenAI
Privacy-Preserving ML
Distributed Systems that actually work in production
