Software house · Prague · since 2009
We build software that survives years in production.
Websites, e-shops, information systems and custom applications. We do not ship demos that fall apart after handover — we run our own SaaS product and know what keeping a system alive actually takes.

What we do
Six areas we know inside out
From a one-off website to a system that keeps a company running for years. Always with one person who knows the project from design to production.
Custom websites and e-shops
Presentations, e-shops and landing pages built to measure. Fast, findable, and built so the client can maintain them without us.
Bespoke information systems
Enterprise systems, internal tools, ERP and CRM integrations. We automate what someone currently retypes into a spreadsheet.
Mobile and web applications
Web applications and native apps for iOS and Android. From prototype through API to store deployment.
IT support and infrastructure
Servers, hosting, Docker, backups and monitoring. We handle operations so the phone does not wake you at night.
Fast, secure UniFi networks
Wi-Fi that covers the whole house or office — and a firewall that genuinely protects you. Ubiquiti UniFi instead of the ISP box. Homes, offices and industrial halls.
AI and automation
Wiring language models into your processes: assistants, document processing, content generation, smart search.
UniFi networks · homes and businesses
The internet your provider will not give you — at home or at the office
The box the ISP technician left behind has one job: to be as cheap as possible. Coverage dies behind the second wall, guests share the same network as your computers, and nobody is looking after security. We build your network on professional Ubiquiti UniFi — for a flat, a family house, an office or business premises.

How we work
Four steps, no black box
You know what is happening, what it costs and when it lands. You see a working build throughout, not just invoices.
-
01
Analysis
We map what you need and what you already have. The output is scope, price and deadline — in writing.
-
02
Design
Architecture, data model and design. Signed off before the first line of code is written.
-
03
Development
Short iterations on a staging environment you have access to the whole time.
-
04
Operations
We deploy, monitor and keep looking after it. Handover is not the end of the relationship.

FAQ
What clients ask most often
How much will it cost and how long will it take?
You get price and timeline in writing after the initial analysis — never as a guess over the phone. Smaller websites take weeks; information systems usually months. We split the scope into stages so you see a working result as early as possible.
Will you take over a project from another supplier?
Yes, we do it regularly. We start with an audit of the code and infrastructure and tell you straight whether it is worth continuing or rewriting. You get the findings even if you then decide to go elsewhere.
What happens after handover?
Handover is not the end. We offer managed service, monitoring, backups and further development under an SLA. The source code is always yours — we never hold you hostage.
Which technologies do you use?
Mainly PHP and Laravel on the backend, React and Livewire on the frontend, MySQL for data, running in Docker behind Traefik. We are not dogmatic — we pick what the project needs and what will still be maintainable in five years.
Do you do networks for flats and family homes too?
Yes — and not only for businesses; a large share of our jobs are family homes and flats. We survey the coverage, plan where the access points go, separate the guest and smart-home networks and configure the firewall. The result is Wi-Fi throughout the house and protection an ISP modem simply does not offer.
Do you work with clients outside Prague?
Yes. Development and operations are remote, so location does not matter. Physical presence is only needed for network installations, which we travel to as standard.
