Joyslu International Limited · Founded 2022
We run online stores. We build the systems behind them.
Joyslu is an import trading company that operates three Shopee stores and a momo channel of its own. Ordering, reconciliation, ad analysis and profit calculation are all handled by systems we developed ourselves, running every day in our own stores. The same capability is available to others: operations automation, website and app development.

Founder
Edwin Lu (Wei-Hua Lu)
Founder and Representative
Edwin Lu spent nine years in the nail industry before founding Joyslu in 2022. He now runs three Shopee stores.
He has done every part of store operations himself, so he knows where the real problems sit. Faced with stockouts, accounts that do not reconcile or ads with no visible effect, he first puts a number on the problem, checks that the judgement holds, and only then turns the method into a system.
At Joyslu, Edwin sets the specification and acceptance criteria, and the development team builds and tests in collaboration with AI. Client projects follow the same process.
How we work
01
You hear when it breaks
Every system has health checks, run logs and failure alerts. Before delivery, we trigger the alert once to confirm it actually reaches a person.
02
Numbers can be checked
Spreadsheets are the source of record, and every result traces back to its source. We do not build black boxes that only engineers can read.
03
The system is yours
We build inside the client's own accounts, and the accounts and files belong to the client. We never take passwords; we use collaborator access or keys only.
04
Results as they are
If nothing changed significantly, we say so. We do not publish client counts or reviews that do not exist.
