Go Beyond the Basics: Master Production-Grade ML & AI
Most machine learning tutorials stop exactly where the real work begins. They teach you the concepts, but they don’t tell you what breaks when you deploy a model to 10 million users.
I’m Rahul Agarwal. Over my career as a Staff Machine Learning Engineer at Roku, Meta, and Walmart Labs, I’ve built and scaled ML systems that drive massive business impact.
MLWhiz | AI Unwrapped is where I share those learnings.
While my free newsletter covers industry trends and foundational concepts, the Premium Tier is the exact playbook I wish I had when I was trying to crack FAANG interviews and level up to Senior and Staff MLE.
When you upgrade, you aren’t just paying for more articles—you are investing in your career trajectory, system design skills, and production readiness.
What You Get When You Upgrade
Here is exactly how the Premium tier accelerates your ML career:
Complete Access to Deep-Dive Series: Free subscribers get an high level overview of my massive engineering series (like the 8-Part RecSys Guide). Premium members unlock the full architecture, system design, and code deep-dives.
The “Scars of Production”: I don’t write generic AI hype. I write about real-world constraints—latency, compute costs, infrastructure bottlenecks, and how to actually scale GenAI and RecSys in production.
Career & Interview Strategy: Insider breakdowns on how to pass machine learning system design interviews at top tech companies.
Full Archive Access: Instantly unlock years of technical backlog, tutorials, and deep-dives.
Direct Access: Priority Q&A in the comments and a direct line to ask me questions about your specific tech stack or career hurdles.
