Senior ML Engineer with 8 years of experience building production systems at 10M+ QPS. Specialized in end-to-end ML lifecycles—from raw data infra to ranking models—with a focus on rapid prototyping and AI-native workflows.

Experience

Founding AI Engineer

Havana - Jan 2026

• Core Architecture: Architecting a scalable evaluation platform for LLM-driven processes (RAG, Agents) using a tech stack focused on rapid iteration.
• Evaluation Frameworks: Designing proprietary metrics to automate the quality assurance of OpenAI, Claude, and Gemini integrations.
• AI-Native Velocity: Reduced prototype-to-production cycles to <2 weeks by architecting an AI-native development workflow using Devin, Claude Code, and Gemini CLI.

Senior Software Engineer

YouTube – Jan 2020 – Jan 2026

AI Products Ecosystem:

• Led the integration of Multi-armed Bandits for UI adaptation. This led to the launch of a novel Shorts thumbnail personalization feature, a new bet for driving YouTube Shorts consumption.
• Delivered projects 2 quarters earlier via Gemini CLI integrated workflows for development and experimentation.
• Architected a TFX classifier that enabled the launch of two new applications in 2022—achieving ~8M daily views and ~4.1M DAU.
• Managed end-to-end lifecycle: roadmap, infra, $50K+ annotation budget, and 4+ cross-team collaborations.

ML Modeling (Ranking & Retrieval Models)

• Developed user intent modeling to boost content diversity and long-session satisfaction. Delivered +1% increase in DAU and +0.5% improvement in average watch time per session.
• Partnered with other core Watch/Shorts/Home teams to design retrieval experiments and evaluate ranking architectures.
