About this session
Practice with a former Google/Waymo Staff Engineer who conducted 200+ technical interviews and was Tech Lead on modern YouTube.com, shipping to 2B+ users. We'll tailor a system design mock to your target role: about 40 minutes of interview and 20 minutes of feedback on architecture, trade-offs and communication. Leave with a concise scorecard and prioritized practice areas. Share your target role and experience level before the session.
Your mentor
I led the complete rebuild of YouTube.com. Today, I help engineers and founders take on bigger challenges: landing a senior or Staff role, growing into technical leadership, or building a real product with AI.
My experience spans two decades, including 12 years at YouTube/Google and Waymo. At YouTube, I took the rebuild from a demo on my laptop to a global launch three years later, setting the technical direction across product organizations. At Waymo, I worked on AI research infrastructure, ML systems and simulation, and was a member of the San Francisco launch team.
I'm now co-founder and CTO of Fictional.ai, backed by a16z Speedrun. I built the technology from the first prototype and lead engineering, hiring and technical strategy. I also created Pony Diffusion, one of the most popular open-weight image model families, used to generate 3B+ images.
WHAT WE CAN WORK ON
• YOUR NEXT ROLE — System design, coding and behavioral interviews, resume feedback, and explaining your impact at the level you're targeting. I've interviewed hundreds of candidates and been involved in hiring at Alphabet. One engineer I mentored went on to land a Staff role at Google; our work was about recognizing the strength of their existing experience and presenting it clearly.
• YOUR NEXT STEP — Promotion strategy, technical leadership, finding work with greater scope, and navigating difficult conversations. If you're unsure whether to stay, move, lead or start something yourself, we can work through that too.
• YOUR AI PRODUCT OR STARTUP — Architecture, LLMs and agents, model choices, evaluation and deployment. For technical founders, we can also work on early hiring, technical priorities and communicating your product to investors. I've built independently and at the scale of YouTube, and know how different those decisions can be.
HOW WE WORK
We work on your actual resume, project, design or career decision. You'll get candid feedback, practical next steps and someone invested in your progress. Sometimes the missing piece is technical; sometimes it's perspective or confidence. I bring humor too, with a background in improv and clowning.
Choose Lite for two 60-minute calls a month or Standard for four. Both plans include chat support, with replies within two working days.
