Custom web development and integrations
For projects where a template is not enough: online booking, product configurators, calculators, complex filters or connections to the tools your company already uses. Price and timeline are set in the quote.
What kind of features
- Online booking with a calendar, open times and validated details
- Product configurators that check option compatibility and calculate the price
- Calculators: instalments, finance, cost estimates
- Advanced search and filters for large catalogues, with results that update instantly
- Comparison tools, map results, multi-step forms
- Integrations with forms, calendars, maps or other external services that offer a public interface
Concrete portfolio examples
In the Volta concept, the PC builder checks the processor socket, memory, power supply, cooling and graphics-card length, and the build is saved in the page address so it can be shared. Clinica Aria has a four-step booking system with a monthly calendar, open times generated per doctor and a calendar file (.ics) at the end. Torsio includes a finance calculator, and Cheie has price-histogram filters and a map view.
These are demonstration projects: they run in the browser with fictional data and send nothing real. In a real project, the part that stores or sends data connects to a server or a service we choose together.
How a custom project works
Specification
We describe together what the feature must do, for whom and which data it uses.
Quote
You get an estimate of price and timeline, plus what stays out of scope.
Prototype
I build a first working version you can test early.
Delivery
We refine, test on different devices and launch.
What affects the price
- How complex the logic is and how many special cases it has
- Whether data must be stored on a server or can stay in the browser
- Integrations with external services and the quality of their documentation
- The number of languages and user roles

Frequently asked questions
Do you build full web applications?
I build complex interfaces and features for websites. For large applications with many user roles and extensive databases, we first discuss the requirements and I tell you honestly what I can deliver and when.
Can you integrate the system we already use?
If the service offers a documented integration interface (API) or a widget, usually yes. I check the documentation before quoting.
How much does a custom feature cost?
It depends on complexity, so the price is set in the quote once the requirements are clear. I do not start work without an agreed price.
