I am currently a tech lead at Meta. My area is platform infrastructure that integrates ML models and serves products including Facebook, Instagram and Oculus. My daily role is to support engineers and managers in the organization with planning, hiring, design review, and XFN collaboration. I have 10 years of industry experience in full stack development and machine learning. Within and outside Meta, I have helped hundreds of engineers landing their first jobs or getting promotion.

Most people find my mentorship helpful in the following three aspects:
1. When you're lost in an ocean of possibilities, I help you sort out which things are most important for you
2. When you're stuck in the code, I help you pinpoint the exact missing piece by sharing code pointers, keywords, and references
3. When you're learning a new technology, I teach you the mentality to understand the end-to-end application of coding concepts and tech design holistically

Roger is an amazing mentor who has seriously improved my career. As a solo founder, he has guided me to launch my first web app on the internet, and now he is currently teaching me the fundamentals of machine learning so I can improve my models to production-ready features. For every call, he takes the time so I fully understand the concepts and code and gives next tasks to do so I can keep learning. Give him a shot and you will not be disappointed!

Very knowledgable mentor on the real world programming problem. He helped me gained a deeper understanding on the programming challenges I faced at my internship and come up up with the most optimized solution. He also helped me with mock interviews, its good to be exposed to real leet code problems that had come up in real interviews in the industry and also know the kind of questions that are most likely to be asked. I would highly recommend Roger

I've been preparing for an internal interview for an MLE role at Meta. Roger did a great job giving me mock interviews for ML system design and data structures/algorithms. Not only did he choose useful questions, but gave valuable feedback each time. Thanks Roger!
