Your China supply
chain has a
loyalty problem.
Commission agents work for the factory. Trading companies pocket the margin. Alibaba can't visit, vet, or negotiate for you. I'm Mara — I charge a flat fee paid by you, and every cent I negotiate goes directly into your pocket. Ten years on China's factory floors. $500M+ managed. 100% job success on Upwork.

a sourcing agent.
Ask yourself: does your agent charge the factory or you? If it's the factory, their income goes up every time your price goes up. Every recommendation they make — which supplier, which price, which quality call — happens in the shadow of that financial relationship.
agency or trading company.
Trading companies buy from the factory and sell to you. The margin in between — 20 to 40% on top of the real ex-factory price — is theirs. You never see the actual cost. And when something goes wrong, the person who picks up the phone is whoever's account manager that week.
from Alibaba.
Alibaba is a directory. It lists factories — it doesn't vet them, visit their production floor, test their real capacity, or negotiate for you in Mandarin. You're making decisions based on profile photos and chat transcripts, 8 time zones away, with no way to know what the factory looks like on a normal Tuesday.
Your factory is overcharging you right now. The only question is by how much.

I built Ulinko because I watched brands get robbed by the people who were supposed to help them.
I've stood on factory floors across Guangdong, Zhejiang, Fujian, and Jiangsu for over ten years. The same thing happens every time: a brand hires a sourcing agent, the agent takes a cut from the factory on every order, and the brand pays 15–30% above the real price for goods they never fully inspect. Every agent I knew worked both sides of the table. I didn't.
Factories never pay me — not a commission, not a kickback, not a red envelope. You pay a flat fee. Every supplier I recommend, every price I fight for, every quality call I make goes in your direction, not the factory's. Ten years. Hundreds of projects. 100% job success on Upwork. Top 10% worldwide. Not because the jobs were easy — because I only take jobs I know I can win.

Same start,
every time.
Every engagement starts the same way, regardless of scope. No surprises, no sales calls, no handoffs to someone you've never met.
We talk for as long as you need. You tell me what you're sourcing and I give you an honest read on feasibility, timeline and likely costs — whether or not you hire me.
If we're a fit, I send a written scope of work with a fixed flat fee. No hourly billing, no surprises mid-project. A standard NDA covers everything from day one.
I handle everything in China. You get clear, regular updates and can reach me directly whenever you need. No handoffs, no account managers, no one you've never spoken to.
Every engagement ends with a concrete deliverable: a report, a shortlist, a video, a shipped order. I debrief you on what was found and what comes next.
Ten years of work,
every job visible on Upwork.
Every engagement I've completed — client reviews, project descriptions, ratings and outcomes — is publicly visible on my Upwork profile. No curated case studies. No cherry-picked wins. The full record, unfiltered, going back to day one.

"Zhang was very professional, available and exceeded my expectations. She found us a shortlist of vetted factories in under a week and caught a pricing discrepancy that would have cost us thousands. I would recommend her to anyone."
"Mara did a pre-shipment inspection that identified defects our previous supplier had signed off on. The shipment was held, reworked and delivered correctly. She saved us from a full returns disaster."
"Very efficient, responsible, and genuinely considerate of the client's needs. Delivered faster than expected, negotiated our MOQ down by 40%, and was reachable at every step."
