I build internal management web apps, automation for Excel/Google Sheets, Zalo integrations and e-commerce websites for small businesses. Fixed quotes, documented handover, warranty after delivery.

Not because your staff are slow. Because no tool is doing the repetitive part for them yet.
Accounting, warehouse and sales each keep their own file. Merging the numbers takes a full day and still doesn’t match.
Staff read the chat and retype it. Orders get missed, quantities get mixed up, customers have to ask twice.
The number on paper differs from the shelf. Over-ordering, stock-outs, and painful end-of-period counts.
Want this week’s revenue? Wait for someone to build the sheet. Every decision runs a beat late.
Sales in one app, accounting in another, stock in a spreadsheet. The same data gets entered two or three times.
You have a site, but no visitors, no enquiries, and changing a line of text means calling someone.
Start with the smallest thing that annoys you. See it work, then expand.
Automatically consolidate, reconcile and send reports from the data you already have. No change to how you work.
Orders, stock, customers and tasks in one system. Works on phone and desktop.
Orders from Zalo, Facebook and Google Forms flow straight into your management sheet. Customers get automatic confirmations.
Company sites, e-commerce and landing pages with lead forms, SEO-ready, editable by you.
You describe how you work today and what eats the most time. I ask questions to understand; nothing is sold at this step.
Clear scope, delivery milestones and cost. No extras unless the scope changes.
At each milestone you try the result and give feedback. Pay per milestone, only for what you can see.
Source code, documentation and training videos for your staff. 30 to 60 days of bug-fix warranty, support via Zalo.
You’re not paying for overhead, sales or an office. You pay the person doing the work.
No middleman, so every requirement is understood correctly from day one.
Full handover, no lock-in, no dependency. Anyone can continue the work.
Scope, milestones, price and warranty written down.

Just describe the work in plain words. I turn it into a solution and explain it without jargon.
Yes. Many automations cost 1 to 3 million VND and save dozens of hours a month. I prefer starting small so you see results quickly.
Small tools 3 to 7 days. Landing pages 1 to 2 weeks. Management web apps 3 to 6 weeks. Exact timelines are in the quote.
30 to 50 percent deposit to start, the rest per delivery milestone. Invoices available on request.
Hourly support or a monthly maintenance package. Since you keep the source code, you can also ask someone else.
I’m in Ho Chi Minh City and can meet within the city. Elsewhere we work over Zalo, Google Meet or email.
A free 30-minute call, no strings attached. I’ll tell you honestly whether software is worth it yet.
