Everything your business needs, under one roof
Forget about juggling multiple vendors. We handle websites, apps, APIs, infrastructure and custom software —including the kind that only runs behind closed doors at your company— end to end.
Web development
We are experts in web development. We help you build a site with the best value for money and a digital experience that reflects your business.
App development
Custom iOS, Android and desktop apps for Windows, macOS and Linux — from public ones in the App Stores to in-house tools (POS, management, inventory) that only run inside your company.
API development
If you need your products or services to talk to other companies, we'll build an API that provides flexibility and ease of integration.
Server administration
We take care of your server's security so risks to your business are minimised.
Migrations
Hosting, server or stack migrations with zero downtime. We apply SSH hardening, automated deployments and pre-cutover verification.
Technical support
We provide service to companies and individual users dealing with issues on their VPS or production servers.
IT consultancy
Technical audits, modernisation plans and ongoing technology guidance for companies that want clarity on what to do — and why.
Best practices by default. You decide with the full picture.
Every project starts with the best security practices available at the time. If your business needs a different call —budget, urgency or a specific requirement—, we walk you through the risks in writing before we commit. No surprises down the line: you stay in control, we stay transparent.

What our clients say
Verified Malt reviews and recommendations from teams we have worked with.
He connected remotely to our Linux server, set up the folders and got the NAS backups running. Always available, fitted in with our needs and even coordinated with our other IT technician to get things sorted. Highly recommended.
Excellent. The work was done quickly and efficiently. Strong Linux know-how, very approachable, and I am looking forward to working with him again.
Glad to have him on the team. Real peace of mind knowing he will sort out anything our clients run into, whether it is code or server config.
