Welcome

Hi, I'm Hung. Welcome to my growth city.

I'm a digital marketer at Roborock Vietnam. I turn ad spend into sales in real stores, then build the dashboards and AI tools that prove it and scale it. Every building here is one part of that job.

Ad Tower

Where the conversations start

Meta, Google, TikTok and Shopee ads for 11 flagship and authorized Roborock stores. I move budget by ROAS, CIR, CPA and store revenue rather than the cheapest cost per message, because a cheap chat that never visits a store is still wasted money.

Watch the blue chat bubbles fly from the tower to the stores. Some turn into gold coins on the way: someone who chatted online, then bought in the store.

Store Thủ Thiêm, Thiso Mall Sala

A new flagship, from opening day to 120% of plan

Thủ Thiêm opened in July 2026. I ran its launch ads and tracked every month whether online leads were walking in and buying. Pick a month: the shoppers walking into the store on the map change with it.

See the numbers as a table

Read from the store's live dashboard. Revenue rounded; Q3 total VND 3,013M against a VND 2,500M plan. October covers 1 to 16 Oct, so it is drawn lighter.

Data Lab

Dashboards and data apps I built

Ads, traffic, sales, customers and products used to live in five places and took most of a day to report. Now they refresh on their own. I also built a warranty analytics app for the after-sales team.

Automation Workshop

An AI assistant that helps the sales team close

A Chrome extension I built for Meta Business Suite. It reads the whole conversation, works out what step the customer is at, and drafts three replies, each split into an answer and one follow-up question. It never sends anything on its own. Try it below.

Interactive demo in Vietnamese, as the store team uses it. Customer messages here are written examples.

Also built

  • Ad follow-up bot. Four messages in 72 hours, then a handover to sales: +65% Fanpage orders at peak.
  • Inbox store marker. Tags each chat with its store from the ad it came from.
  • Content analyser. Finds posts that earn reach and suggests reposts per store.
  • Sales playbooks. Chat process, catalog ads and group posting SOPs the store team runs today.
