About
Hi, I am a Senior Machine Learning Engineer and the ML lead for a 30+ person organization at a major FAANG company. I specialize in e2e machine learning, helping technical professionals take full ownership of the full ML lifecycle, moving projects from initial experimentation to global production scale.
Throughout my career, I have led personalization initiatives for over 400M customers, driving $600M+ in annual revenue. I bridge the gap between "Science" and "Engineering," turning Jupyter notebooks into robust, production-ready systems using AWS (SageMaker/Bedrock).
The Hiring Insider: I am actively involved in the hiring process and final hire decisions for my organization. Having conducted 150+ technical interviews across Coding, ML System Design, and Behavioral loops, I know exactly what technical signals and leadership traits result in a "Strong Hire" recommendation.
How I Help You: Whether you are an SDE, Data Analyst, or Data Engineer, I provide the tactical blueprint to help you:
- Master the full lifecycle of ML to lead high-impact initiatives.
- Translate your current skills into the production-ready language FAANG recruiters look for.
- Navigate the interview bar with direct feedback from an active decision-maker.
