About Daniel Xu

Daniel Xu is a Member of Technical Staff at Anthropic. He is proficient in Chinese. Colleagues describe him as "I worked with Daniel hand in hand starting from when we were a small but mighty team all the way to the mature and large organization. Daniel has this amazing talent to think as an engineer, product manager, analyst, data scientist etc. He can take on any and every role in the team which makes him a strong product personnel. He was very generous with his time to grow the individuals around him, he is a great colleague to work with. Hope that our paths will cross at some point again.", "I had the pleasure of working with Daniel for the latter half of 2021, and I thoroughly enjoyed the experience Daniel is a dynamo, kicking off and driving to completion important collaboration across all of Meta (Facebook, Instagram, and WhatsApp) on both first party and developer experiences. He convinced engineering teams to prioritize several moonshot initiatives that represented significant step-function increases in anti-scraping capabilities. Also, he aligned growth leadership to audit and redesign key privacy settings which had outlived their usefulness. In addition, he incepted and scaled up our Red Team process for anti-scraping, which empowered Meta to proactively seek out and validate scraping risks before they could be exploited by external parties to harm users He accomplished this through impressive work ethic, intelligence, and impressive depth of expertise in the privacy space. When we were short-staffed, Daniel took on a couple of extra workstreams (that couldn’t be dropped) so that our group could complete our goals. In these projects, his rapid ramp and first principles thinking were on full display, as he achieved impressive results in the first several months. In terms of privacy, Daniel consistently drove the group’s thinking forward and prioritized several projects that led to high-paying long term bets.", and "It has been an absolute delight to work with Daniel. He is super collaborative, thoughtful and in general such a solid partner to have. He also has a tireless work ethic and is always looking to take on new challenges. He is someone who is equally skilled at making a product successful, but also never loses site of his long-term vision and always iterates towards that. What I loved the most was Daniel's passion to push for the right decisions, get leadership bought in and bringing the team along. Having him around as an ally and a sounding board made hard problems seem easy. Thank you for everything, Daniel!"

Product Lead

Redwood City, California, Us

I'm helping build the next generation of data-centric ML Infrastructure!

Apr 2023 - Present

Product

I helped Meta fight botnets trying to scrape user data. I led two teams within Privacy Infrastructure > External Data Misuse [Scraping Red Team] Our mission was to uncover, stack rank, and eliminate scraping vulnerabilities that pose existential risk to Meta. We partnered closely with multiple security vendors (total operating budget of $4M / Year) who helped us identify 100's of potential vulnerabilities. After triaging candidate threats for ongoing attacks, we replicated them in controlled environments in order to validate the efficacy of our bot detection systems across various surfaces like GraphQL, contact importers, etc. See the attached links for specific Red Team case studies[Scraping Data Platform] Our mission was to prevent Meta platform partners from utilizing developer APIs to scrape native FB experiences. We built tools that matched key signals between 3rd Party APIs and 1st Party endpoints, providing legal teams with sufficient evidence to launch lawsuits against scraping actors.
