I listen.
You know your business. I ask questions, follow the steps, and work out with you what is worth changing. Sometimes the answer is a small fix, not new software.

Software
that fits.
This is an exciting time for small business. AI enables faster and cheaper software development, so now small companies may also have tools made specifically for them.
It starts with
a conversation.
Maybe you use spreadsheets, paper, or a system you keep working around. Show me what happens on a normal day — and where it gets awkward.
We build it together.
After our first detailed conversation, I aim to have a usable first version ready in about a week. You try it with real work, we talk, and I make changes.
You use it. I look after it.
Your team opens it in a browser, on a computer or phone. I handle hosting and routine maintenance, and we can improve it as your needs change.
A few things
I’ve worked on.
Practical tools for actual businesses. Most of the useful work happens behind a login; these links lead to their public websites.

Project managementThe team worked with spreadsheets and paper. I built a tool to bring projects and their details together, making it easier for the owner to see what is happening across the business. We tested and adjusted it together, feature by feature.

Bookings & automationBooking, administration, payments, and building automation. I built tools for day-to-day operations and connected the software to systems in the building.

Engineering & operationsMy background includes engineering and building custom tools for our own operations. It is the same habit: understand the work, then make a tool that helps.
You can see
what you’re paying for.
I charge by the hour. Your private project page shows what I worked on, the time spent, and the running total. Before work starts, we agree what to tackle and can set a spending limit. The price comes from the actual time spent.
Building your software
€40 / hour
A small project can take as little as 10 hours — €400 at this rate. After our first detailed conversation, we agree what to tackle first and estimate the work involved.
The first conversation is free. After that, understanding the workflow, building, changes, and testing use the same hourly rate.
- Actual time recorded, with a description of the work.
- A working version early, with feedback along the way.
- After payment, you get the code and data, and another developer can take over.
Keeping it running
€180 / 6 months
Paid in advance. Includes hosting, backups, updates, and small routine maintenance.
- The first 30 days of hosting are included.
- I aim to reply within 3 days. I work alone.
- Larger changes are logged at the agreed hourly rate.
When the software is ready to try, you see the total for the hours worked and use it in your business for a week. If it is worth that amount to you, you pay for the recorded work and keep using it. If you decide against it, you pay nothing, including for understanding the workflow, changes and testing. I switch off the service and do not hand over the software.
When does the maintenance fee start?
The first 30 days of hosting are included, starting when I set it up. Your one-week trial starts when the software is ready to try. If that takes us past the first 30 days, I cover the gap until your decision. Maintenance starts after the included period and only if you keep the software, billed for six months at a time.
What counts as extra work?
Tiny routine fixes are included. If a requested change takes more than five minutes, I log the actual time. Small amounts can be combined with your next invoice; I do not round a short change up to a whole hour.
What if something breaks?
Contact me directly. I aim to respond within three days.
What if I want to leave?
After you have paid for the work, the code is yours. You have access to your code and data, and another developer can take over.
Can you look after our public website too?
Yes, where it fits the same hosting setup. Building or moving the website is hourly work; it need not add another recurring hosting fee. We can discuss email hosting too, including the migration and support you need.
You’ll be talking to me.
I’m Greg, an engineer with more than ten years of building custom software for myself and others. I enjoy understanding how a business works and making useful tools for the people running it.
AI is how I work. It helps me build and change software quickly, making small, highly specific projects practical. Your software only needs AI inside it when that actually helps.
I work independently. You talk directly to the person who listens, builds, and looks after the result. If I don’t think I can make something useful for you, I’ll say so.

What is taking
too much of your time?
Tell me what your business does and what feels harder than it should. An email or a message is a good place to start.
