Custom software
you can rely on.

I build custom business systems, applications and websites. I can connect separate tools, reduce manual work or help your product grow.

AI-accelerated development. I use AI to speed up routine development tasks; I remain responsible for solution design, technical decisions and the final review.

Services

What I can build for you

From an internal tool to a customer-facing app. I can help with a new project or develop a system you already use.

Business systems and integrations

Internal tools, automation and connections between services that currently work in isolation. Less manual data entry, better visibility and software that fits your processes.

Custom applications

From the first version of a new service to the next stage of an established product. I build web or mobile apps that serve a real user need and can keep growing.

Websites and customer portals

A company website, content platform or portal for your customers. Fast, accessible and easy to manage, with a clear purpose.

Development and modernisation

I can take on part of an existing project, help reshape its architecture, review code or add features. I build on what already works.
