Custom applications for companies · Hanoi
I build applications that take over your work.

Off-the-shelf programs rarely fit what you actually do. So I build you something of your own: a system shaped around the way you work, running on real data and owned by you. After that I stay on it and keep it alive. For small and mid-sized companies, and for departments inside larger ones.

Clients and teams I have worked with
What I build for you
Not a kit of parts, just what gets asked for most. If you recognise one of these, something can almost always be built for it that does the job in seconds and never makes a careless mistake.
One system instead of five spreadsheets
Customers, orders, quotes and invoices in one place, with proper rights for your team. Replaces the spreadsheet that actually runs your company.
A tool for reports and documents
Merge spreadsheets, build a deck from current numbers, produce quotes and minutes in the right layout. Built once, it takes seconds instead of half a day.
A connection between your programs
No more copy-and-paste between inbox, spreadsheet and system. What comes in lands where it belongs, completely.
Something that keeps running in the background
The daily check, the weekly report, chasing open quotes. It runs by itself and only speaks up when something actually happened.
A tool that searches for you
Prices, suppliers, addresses, tenders, competitors. Instead of clicking for hours you get a finished list you can work with straight away.
A website wired into the system
You edit the content yourself, enquiries land in the system rather than an inbox, and the numbers sit in one view.
What I offer
One service, not a catalogue.
I build you your own application and keep it running afterwards.
You show me how you work today and I build the system that takes that work over: shaped around your way of working rather than the other way round. After that it runs in production, belongs to you and grows when something changes. Looking after it is part of the deal, not a separate business. What it costs I tell you as a fixed price, once I have seen what it is about.
- Shaped around your work, not around a product
- Fixed price as soon as the scope is clear
- Running it and looking after it are included
- Source code and infrastructure are yours
Three systems that already exist
Some applications come up so often that I do not rebuild them each time. These three are already running for clients and go live considerably faster than a new build.
Website wired into a CRM
An enquiry from the website does not land in a mailbox but directly as a record in the CRM. Quotes and invoices are created from there, without anyone retyping data.
- Enquiry form linked straight to the record
- Customers, quotes and paperwork in one place
- Role permissions and an audit trail
- Paperwork as PDF in your own visual identity
A website you maintain yourself
You change content in your own area, see it as a draft and publish it yourself. No content system to maintain, and nothing that wants patching on a Friday evening.
- Your own editorial area under /admin
- Review the draft, then publish
- Live in about 35 seconds
- No cookie banner, because no third-party tracking
Analytics access for your website
Cookie-free visitor numbers, your Google Search Console data and your form enquiries in one view, with a separate login for your team.
- Cookie-free, so no consent needed
- Search terms and rankings included
- Form enquiries archived in the same place
- A separate login per client
I do not quote blanket prices, because the effort depends on the application. After a first conversation you get a fixed price I hold myself to. For running it afterwards I name a fixed monthly amount.
How a project runs
Custom applications rarely fail on the programming. They fail because nobody trusts them or nobody looks after them afterwards. That is exactly what this process is built around.
- 01
Look at it
I look at how you work today, count where the hours go, and also tell you where something custom-built is not worth it. That list is often the most valuable one.
- 02
Smallest version
The simplest variant runs on real data in production first, not a demo that only works in the meeting.
- 03
Make it production-ready
Container, monitoring, backups, documentation. Built to survive a holiday, a handover and me.
- 04
Running it and building on it
I do not disappear afterwards: I keep the system running, extend it when something changes on your side, and I am reachable when it jams. Handing it over works just as well, it only has to be decided. Anything nobody looks after turns into a risk.
One point that comes up every time: the source code and the infrastructure are yours. No platform you cannot leave, and no licence that expires with our contract.

What is costing you time every week?
Describe in two or three sentences how you work today and where it gets stuck. You will hear from me within one working day on what could be built for it and roughly what it takes. That assessment is free.
