Hands-on support
Hello 👋🙂 I help founders, entrepreneurs, operators, and analytics teams design data-driven decision systems, not just dashboards.
I have 10+ years of experience in Data Science, Machine Learning, and Business Analytics across large-scale businesses (including retail and financial services), where my work focused on answering questions like "What actually drives revenue and growth?" & "Which metrics matter vs. create noise?"
My strength is end-to-end analytics design (through machine learning, data science, AI):
- Metrics & KPI framework design (sales, marketing, operations)
- Growth & performance analysis (what drives results, what doesn’t)
- Analytics system setup (how to structure data before it gets messy)
- Building analytical frameworks that connect operations → performance → strategy.
If you’re building or scaling a business and want help turning data into confident decisions, I’m happy to connect. If you are not sure, feel free to grab 25 mins from my calendar to see whether and how I could assist.

5 out of 5 stars
I’m writing this not just to say polite thanks—this is genuinely personal. Cheng mentored me over the past two years; our bi‑weekly calls became one of the most impactful parts of my growth in data science. She consistently challenged how I think, helped me sharpen my problem‑solving method, pushed me to level up—especially during the interview‑prep grind when I was putting in late nights to get ready. What stood out most is that Cheng’s support went beyond technical guidance. During some difficult time, her steadiness plus encouragement gave me real stability, confidence when I needed it most. That kind of mentorship is rare. If you’re looking for the kind of mentor who is intellectually rigorous, practical, genuinely invested in your growth, I highly recommend Cheng.

I was working on a career transition after finishing grad school in data science. Cheng helped me overhaul my resume, gave me tips on using the major job sites more effectively, showed me online resources that led to some of my first callbacks, and was available to help at every step of the interview process. No fluff, no nonsense, lots of practical and actionable advice. Thanks to her help, I was able to secure a job offer at a more senior level than I had expected. Highly recommended!

Cheng is one of the best in the business when it comes to navigating the data science and analytics job market, truly unmatched in her insight and support. I came to Cheng after struggling to land interviews, despite having five years of experience. She helped me completely reframe my resume and approach, and soon after, the interviews started rolling in. Beyond resume help, she coached me through interview prep—what to say, what not to say, and how to tackle the technical portions with confidence. Thanks to Cheng’s guidance, I landed the role I’d been aiming for. If you’re feeling stuck or overlooked, Cheng is exactly the person you want in your corner. Her ability to challenge you while keeping you motivated is rare and incredibly effective.
