Machine Learning practitioner with 10+ years of experience scaling data systems at top-tier Silicon Valley companies. I’ve led impactful projects across Machine Learning, Recommender Systems, and large-scale infrastructure, and have been a people manager for over seven years. I actively interview ML Engineers and Engineering Managers, giving me a sharp lens into what top companies look for.
I’m happy to support you with:
- Resume reviews
- Mock interviews: system design, ML design, behavioral, project deep dive, and Engineering Manager interview
- Presentation rehearsals
- Role-playing critical conversations (e.g., asking for a raise or promotion)
- Career transitions: into management or into Machine Learning
- Career growth topics that matter to you (e.g., goal setting, project planning)
- Deep dives into ML technical topics of interest
Whether you're preparing for your next big opportunity or navigating a career pivot, I’ll meet you where you are and help you move forward with clarity and confidence.
5 out of 5 stars
Xun is deeply knowledgeable about Machine Learning systems and has supported me with genuine dedication. She digs into the details and asks exactly the right questions — the ones that expose gaps you didn't know you had. Her guidance was especially valuable for my ML Q&A interview prep. She gave practical hints and helped me prepare in the right way, not just more. What I appreciated most is her honesty. Xun never claims to know something she doesn't, which built real trust in everything she does say. I strongly recommend Xun to anyone preparing for ML interviews. She's a great mentor.

5 out of 5 stars
Xun is an exceptional mentor who knows exactly what it takes to reach the Staff level. Before working with her, I felt stuck and unsure of how to bridge the gap to the next stage of my career. Xun provided the critical insights I needed to unblock myself and, more importantly, the conviction that I could actually get there. Her feedback is incredibly specific, grounded in her deep experience as an ML Engineering Manager who has successfully coached her own engineers to Staff. She helped me demystify what "Staff-level impact" looks like and turned our high-level strategy sessions into a concrete action plan that I’ve already begun executing with my manager. If you’re looking for a mentor who balances big-picture vision with practical "next steps," Xun is the person you want in your corner.

I was glad that I had several calls with Xun. She managed to prepare me for a behavioural and system design interview at a big tech company using just a few sessions (offer received!). She was very engaged in conversation, and her comments and advice were always exact and understandable. I would highly recommend Xun and hope to speak with her again later during my career development
