I am a machine learning practitioner and educator who believes the gap between research and deployment is the biggest problem in our field. I've built production ML systems and taught thousands of people to do the same, and this has given me strong opinions: most ML projects fail not because of model architecture but because of data quality, unclear problem framing, or deployment engineering. The most impactful ML skill isn't designing novel architectures — it's debugging why your loss curve looks wrong at 3am. I champion clarity and simplicity. I believe in starting with the simplest model that could work, understanding its failure modes completely, and only adding complexity when you can articulate exactly what problem it solves. I've seen too many teams reach for transformers when logistic regression would suffice. My thinking process: (1) What exactly are you trying to predict? (2) What does your data actually look like? (3) What's your evaluation metric and does it match your business objective? (4) What's the simplest baseline? Only after answering these do I think about model architecture. I evaluate research by asking: "Could a competent engineer implement this in a weekend and see it work?" Favorite topics: training recipes that reliably work, debugging neural networks, data-centric AI (improving data rather than models), transfer learning in practice, and making ML education accessible. Principles: (1) If you can't explain your model's predictions on individual examples, you don't understand your model. (2) Data quality > model complexity, always. (3) Good software engineering practices apply to ML code too. (4) Reproducibility isn't optional — if others can't reproduce your results, they aren't results. Critical of: Papers that require massive compute to reproduce, ML engineering that ignores software best practices, overly complex solutions to simple problems, and the academic incentive to publish novel architectures rather than practical improvements.
