Don't rush to replace your system. Fix what's actually broken.
Slow website, servers that keep going down, a previous vendor who stopped answering, staff still typing data in by hand. I'm a software engineer. I find the cause, fix it and keep the system running. You work with me directly, with no account managers in between.
Get data from invoices, orders and forms into the software you already use without retyping it. Always starts as a small trial project.
Read invoices, orders and forms (PDF or scanned), check them, send anything uncertain to a person, then push the data into Excel, accounting software or a CRM.
Keep data in sync between your website, CRM and internal systems through their APIs.
Scheduled reports and alerts. When something fails, you can see where.
Indicative price
US$1,150–3,070 for a trial project
Timeline
2–6 weeks, depending on how many systems are involved
The trial has a fixed scope. Before starting we write down how things work today (how long it takes, how many errors) so we can compare afterwards. Going further is quoted separately.
Software can't read Vietnamese documents with 100% accuracy, especially blurry photos. That's why a person always checks the results.
You keep the client and build the front end. I handle the backend, API integrations, servers and deployment under your name. Priced per project or per month.
Prices and timelines above are indicative. USD prices are converted from Vietnamese dong at about 26,100 VND per US dollar (October 2026). The written quote states the final amount and currency once we've agreed the scope.
How I work
4 steps, agreed in writing before work starts
I don't go straight from one phone call to a big contract. Before any work starts, you know what will be done, when it will be finished, and how we roll back if something goes wrong.
1
Understand the problem
How it's affecting the business, what the system looks like today, and any limits on time or budget.
2
Review and agree the scope
What gets done, what gets delivered, how we sign it off, the risks, the cost and the timeline. All in writing.
3
Deliver in small steps
Every change is checked before it goes live, and there's always a way back to the previous version.
4
Hand over
Notes on what changed, what I'd do next, and a maintenance plan if you want one.
Access and security
I only ask for the access the job actually needs.
Passwords and keys go through a secure channel, never through the form.
When the work is handed over, I give access back or you change the passwords.
Happy to sign an NDA if you need one.
About me
You work with me directly
For more than 15 years I've built and run systems at major technology platforms in Vietnam. At GocFix, the person you talk to is the one reading the code, configuring the servers and answering for the result.
I only quote for a fix once I understand the problem. Diagnosing over the phone usually means fixing the wrong thing.
Keep what already works
Replace only what needs replacing. Starting over costs money and time, and tends to bring new bugs.
One person is responsible
You talk to the person doing the work. If the project needs another pair of hands, I'll tell you first and only bring someone in if you agree.
It still runs after handover
Deployment, backups, logs, a way to roll back and documentation are part of the job, not extras.
AI only when it's worth it
Most automation doesn't need AI. When I do use it, a person always checks the results wherever a mistake would be costly.
Examples
Before and after the fix
Illustrative examples, not specific client projects
Fragile server, manual deploys
Server
Before
The app runs on a VPS, every update is done by hand, and SSL has expired a few times.
After
Moved to Docker Compose, SSL renews itself, backups run automatically and a restore has been tested, with notes so someone else can deploy.
The report page takes forever
Database
Before
Staff wait every time they open a report.
After
Found the slow queries, added indexes without taking the system down, and kept an eye on it afterwards.
Invoices typed in by hand
Automation
Before
The accountant retypes every PDF invoice into the software.
After
The system reads the invoice, a person checks anything it's unsure of, and the data goes straight into the software.
The previous developer left
Legacy
Before
Nobody understands the system and everyone is afraid to touch it.
After
A Health Check, the biggest risks fixed first, and documentation so the system no longer depends on one person.
Scope
What I don't take on
If what you need falls outside what I do, I'll say so at the start so you don't lose time.
New website design or brand identity.
Mobile apps.
Full ERP implementations.
24/7 or unlimited support.
Penetration testing or security certification.
FAQ
Common questions
Will you work on a system someone else built?
Yes. I usually do a Health Check first to understand the system, then quote for the fix.
Is GocFix a company or one person?
GocFix is my own practice, and I'm the only engineer. You work with me from start to finish. If a project needs more people, I'll tell you first and only bring someone in if you agree.
Do I have to use AI?
No. I go for whatever is simplest, stable and cheapest to run. AI only comes in when the benefit is clear.
How long does it take?
A Health Check usually takes 2–4 working days, a fix-and-stabilize sprint 1–2 weeks, and an automation trial 2–6 weeks. The exact timeline depends on the work and when I get access, and is written into the scope before we start.
How is the price worked out?
By scope, difficulty and risk. Prices on this page are indicative. The actual quote always comes in writing. If you go ahead after a Health Check, its fee is credited toward the repair work.
Do we sign a contract?
Yes. Before any work starts, the scope, cost, timeline and how the work is signed off are put in writing. I'm happy to sign an NDA as well if you need one.
Is there support after handover?
Yes, through a monthly maintenance plan billed by the hour. Response times and what's covered are spelled out in the contract.
How many projects do you take each month?
Not many. I work alone and want to do each one properly. If I'm booked up, I'll tell you when I can start.
How do you keep code and data safe?
I only ask for the access the job needs and give it back at handover. How data is handled and an NDA are agreed before we start. Please don't send passwords or API keys through the form on this page.
Contact
What's going on with your system?
Write a few lines about the problem, what you're running and what you'd like to end up with. I'll read it and reply to set up a next step.
I only take on a few projects a month so each one gets proper attention.
