Cannot say enough amazing things about Hwei. She is extremely talented at her job, I can say with 100% confidence she can do anything and everything you need help with / she wants. And on top, a team player who uplifts those around her. She guided me in my exec journey and took our vision as her own, bringing it to life. We are in a much stronger place as a company after working with Hwei, we can't wait to continue our partnership with her :)

Hwei is truly one of a kind. I’ve worked with her for over two years on many data science and AI projects, and she played a key role in managing our community of hundreds of technical professionals. She’s highly capable technically, always punctual, communicates seamlessly, and when she says she’ll handle something, it’s done. On top of that, she’s a great team player and has coached hundreds of our members in their careers.

Nobody understands your business like you do, and you know exactly the bottleneck you want gone. You want someone who can see it just as clearly, bring it to life the way you imagined, and build it to last. That has been my track record.
Imagine handing off your idea, and what comes back makes you say, "This is exactly what I had in mind!" That is the feedback I hear most from my clients.
Here's what working together looks like: You explain the vision once. I turn it into a clear plan, build the system end-to-end, and ship something your team can actually run and trust.
Whether it's an LLM or RAG application, an AI agent, or a forecasting or anomaly-detection engine, it is handed over to you already deployed in production, documented, and yours to keep building on.
What my clients say:
→ "She took our vision as her own and brought it to life."
→ "When she says she'll handle something, it's done."
→ "Hwei is the proverbial needle in a haystack. She gets it. She gets it done."
Recent projects:
• A US women's health startup: I led the AI intelligence layer at the core of their v1.0, live before their funding raise.
• A Fortune 500 consumer brand: I built a stability testing platform that turned days of manual work into seconds.
• An Italian telecom compliance consultancy: I built an LLM document-processing pipeline that cut review time from days to minutes, with zero false approvals.
• A Dutch water consortium: I built an anomaly-detection dashboard that flagged genuine contamination events with zero false alarms.
