• Identify and resolve issues related to data quality, model drift, and system performance in production.

AI & LLM Applications

• Apply LLMs and foundation models to recommendation-related problems such as content understanding, user intent modeling, and feature generation.
• Prototype quickly, validate with experiments, and push successful ideas into production.

AI-Driven Development

• Embrace AI-assisted development workflows, including LLM-powered coding, debugging, and analysis.
• Apply AI across feature ideation, prototyping, and experiment analysis.

0 → 1 Innovation
