About

Hi! I'm a Senior Data Scientist with a decade of experience in data science and analytics, including 5+ years in the tech industry. I'm currently working at DoorDash and an ex-Meta. My journey started in a traditional industry, so I understand the challenges of making the switch to tech. Experienced in product analytics, I'm happy to guide junior data scientists or those looking to break into the tech world. If you want interview prep (mock interviews, study strategies), I'd love to help – I've conducted over 300 interviews. Let's work together to reach your goals.

I had the pleasure of working with Mei as I prepared for my data scientist interviews, she is one of the most knowledgeable and insightful coaches out there - her deep expertise in experimentation and technical depth across the entire data science stack made a big difference in my FAANG interview prep. She provided incredibly clear, structured guidance on experiment design, product case studies, metrics interpretation, and high-impact project storytelling. I highly recommend working with her.

Mei is an incredible mentor who greatly helped me prepare for my product case interview. She offers unique and deep insights based on her extensive industry experience, which allowed me to develop a much deeper understanding of the case study than I had before my mock interview. I highly recommend her if you're looking for valuable feedback and advice from a seasoned data science professional. Thanks, Mei, for all your help in preparing my case study!
