Over 7+ years on Upwork, I've helped startups and enterprises across sectors - Marketing, Healthcare, Law, Education, and Agribusiness - translate AI into measurable business ROI by building the right data and ML foundations.
Whether collaborating with 1000+ employee companies or lean 2-person startups, I adapt to the teamโs needs: reporting directly to CEOs or CTOs as an AI/Data Lead, or integrating as a hands-on contributor alongside in-house developers.
I bring a โbrain-for-hireโ + hands-on mindset - tackling strategic and technical challenges with equal enthusiasm, always focused on delivering outcomes, not overhead.

๐ Unlock faster, smarter sales growth with AI-powered workflows - without hiring in-house tech experts, managing complex tools yourself, or getting stuck in rigid, one-size-fits-all systems.
I help remote B2B service firms and agencies simplify their sales and marketing processes with lean, AI-powered workflow automation that:
โ Frees your team from repetitive tasks
โ Improves lead quality and conversion rates
โ Shortens sales cycles and speeds up revenue
โ Delivers measurable ROI - within weeks, not months
Many teams I work with have tried adding tools or hiring freelancers before. But too often, the results donโt stick:
โ Overbuilt systems and a ton of code no one adopts
โ Flashy AI hacks that create more work
โ โBig techโ solutions that donโt fit your teamโs reality
โ Projects that drag on endlessly without clear ROI in a human's lifetime
If you have experienced this, then you're in the right place. ๐
I partner closely with growth-minded leaders to design and deploy automation that fits your processes, your people, and your goals. No bloated tech stacks. No overengineering. Just smarter, simpler workflows that scale.
Hereโs how I can support you:
๐ Sales & marketing workflow automation (lead capture, qualification, follow-up)
๐ CRM optimization & integration (HubSpot, Airtable, custom APIs)
๐ AI-powered outreach systems (personalized messaging & proposal generation)
๐ Building smart AI workflows with N8N, Make.com, and LLMs
๐ Designing and deploying AI Agent systems with Relevance AI
๐ Revenue operations process design (RevOps)
I bring a rare mix of:
๐ Business strategy (what matters for growth)
โ๏ธ Technical execution (making systems actually work)
๐ฅ Team adoption (so the change sticks)
This isnโt โtech for techโs sake.โ Itโs about enabling your team to move faster, win more deals, and focus on high-value work.
How does working with me look like?
โถ๏ธ We analyze where you are at.
โก๏ธ We collaborate to set realistic goals.
โคด๏ธ I build a little (or work with a team to build).
๐ We talk about findings and restart.
By iteratively refining solutions, we effectively turn potential into progress and investments into ROI.
๐ฉ Ready to streamline your sales processes and unlock smarter revenue growth?

I'm an Upwork Expert-Vetted Data Scientist who covers what usually takes two specialists: classic ML and modern LLM systems, shipped to production.
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. 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:
โ "She took our vision as her own and brought it to life."
โ "When she says she'll handle something, it's done."
โ "Hwei is the proverbial needle in a haystack. She gets it. She gets it done."
Recent projects:
โข A US women's health startup: I led the AI intelligence layer behind their production multi-agent chatbot, live ahead of their fundraise.
โข A Fortune 500 consumer brand: I built a shelf-life forecasting platform that turned weeks of manual modeling into 30-second predictions.
โข An Italian telecom firm: I built an LLM document validation pipeline that cut compliance review from days to minutes, with zero false approvals against their own 99.7% precision target.
โข A Dutch water consortium: I built an anomaly-detection system that caught real contamination with zero false alarms, then grew it into a 12.3M-measurement data platform that their own team can run without a developer.
โ Expert-Vetted ยท Top 1% on Upwork ยท 100% Job Success
โ ML and AI since 2018 ยท 8 published papers ยท Trained at Fraunhofer SCAI and the University of Hamburg
