01
Connect your systems and automate the work
Let information flow between your tools without anyone having to copy and paste. I build integrations and workflows between, for example, your website, CRM, finance system and booking.
Web development, AI and automation · Stockholm · since 2004
Less manual work. More room for your business.
I help companies and organisations connect their systems, automate recurring tasks and build digital services tailored to how they work.
Need a smarter quoting flow, a customer portal or help using AI in your business? I take you from idea to working solution – with over 20 years of experience and direct contact throughout the project.
What would you like to stop doing by hand?
Entering the same data several times. Looking for information in different systems. Compiling reports or creating every quote from scratch.
I help you find the steps that take time and build solutions that make the work easier.
02
Use AI where it adds value
Make it easier to find information, process documents and prepare material. I help you choose a clear use case and connect AI to your workflows, with the ability to review the result before it is used. We decide together which AI services are used and where your data ends up.
03
Build the tool that is missing
When your existing tools fall short, I build what you need: quoting systems, customer portals, booking, internal tools or reporting. We start with what matters most and develop further based on how the solution is used.
04
Turn an idea into a digital service
Do you have an idea for customers, members or your own organisation? I help you make it concrete, test a prototype and build a first version that can be used for real.
05
Develop your website and e-commerce
I build and develop websites and online shops that are easy to use, update and connect to the rest of your business.

The house is drawn in 3D while the price is being calculated.
Selected project · Quoting & drawings
Quote, 3D model and drawings for greenhouses
A sales system for the greenhouse manufacturer Sweden Green House. The salesperson sets dimensions, doors, colour and stove in six steps. The system calculates the price and simultaneously draws the house in 3D, as a foundation drawing and as a building-permit document.
Client: Sweden Green House
- Finished quote as PDF, with no manual calculation
- 3D model that follows the dimensions as they change
- Foundation drawing at 1:50 scale for whoever pours the foundation
- Building-permit drawing with plan, section and four elevations
Own product · Ticketing system
Scantré – ticketing system for culture and events
A ticketing system I have built and run. Admin panel, purchase widget for the organiser's own website and a scanner that works offline – parts of the same system, so nothing needs to be exported or entered again.
- Purchase widget embedded with one line of code, payment via Stripe
- PDF tickets with QR code straight to the inbox
- Scanner on the staff's phones that works offline
- Reports with sold versus checked-in per screening
01 / 04
Revenue, tickets sold and occupancy for every upcoming screening.
Get started
A first step at a fixed price.
You don't have to commit to a large project. Start with a well-scoped engagement. After the first call you get a fixed price for exactly that scope, before you decide.
Mapping a workflow
We go through a workflow that takes time today, for example quotes, orders or reporting. You get a description of how it works now, where the time goes and a concrete proposal for what can be automated.
Ask about mappingPrototype of an idea
You have an idea for a digital service or an internal tool. I build a clickable prototype that you can test with users and use as a basis for decisions.

- 01The first call
Free of charge. You tell me what takes time or isn't working, and we work out whether and how I can help.
- 02Proposal at a fixed price
You get a short description of what will be done, what it costs and when it can be ready. Only then do you decide.
- 03Built in stages
I build what matters most first and show the result as I go, so you can test and adjust along the way.
- 04Launch and maintenance
The solution goes live, you get a walkthrough, and I stay on for support and further development.

Testimonials
What clients say.
We used to price every quote and draw by hand. Now the salesperson enters the dimensions and gets the quote, 3D model and drawings in one go. Andy took the time to learn how we work and built the system around it.
Lucky Cat and Andy are skilled at getting to grips with complex processes and understanding our customers' needs. From that, he develops smart web solutions that create real customer value. At the same time, he always keeps the bigger picture in mind and helps us develop our web presence in a modern, standardised way.
Andy has improved our website many times over, and our clients' sites too. No task is too big and no integration too complicated to pull together. WooCommerce and FileMaker? No problem.

A developer who sees the whole picture.
I'm Andy Karlsson, a freelance developer in Stockholm. Since 2004 I have built websites, e-commerce and business systems for everyone from non-profits to national organisations.
I work across the whole chain – database, integrations, interface and operations – and you deal directly with me throughout the project. I have no employees and no middlemen: the person you talk to is the one who builds. Invoices come from my company, Lucky Cat Industries AB.
Specialist in WordPress and Laravel
Looking for a developer for an existing WordPress or Laravel project? I take assignments directly, as part of your team or as a subcontractor to agencies.

You are not locked in to me.
You own the code
All code belongs to you and lives in a repository you have access to. Domains, hosting and services are in your name.
Built to be handed over
I use established technology and document the solution, so another developer can take over if that is ever needed.
Maintenance after launch
I stay on after delivery for operations, updates and further development – ongoing or when needed.
Start with a concrete problem.
You don't need to know which system or technology is needed. Tell me what takes time, what isn't working or what you want to be able to offer.
In a first free call we go through the need and work out a sensible next step.
