From showcase website to business application.
We design and build custom websites and functional web applications, with a proven method, mastered technologies and fast delivery. From requirements to deployment, including security and hosting.
Custom websites
A website is not a template. We build your digital presence using a structured method: defining objectives, target audience, content, design and styles, in that order. The result is a consistent, performant and maintainable site.
- Objectives and target audience definition (framing workshop)
- Information architecture and sitemap
- Custom design aligned with your visual identity
- React, advanced HTML/CSS or solution adapted to the need
- Technical SEO and performance optimization (Core Web Vitals)
- Mobile-first responsive design, WCAG accessibility
Proven method: objectives, design, content defined in 1 to 2 sessions
React, HTML/CSS, PHP: we choose the right tech, not the trendiest
Deployment and management via Infomaniak (Swiss) or your infrastructure
A first functional deliverable in days, not months
Dashboards, management tools, administration interfaces
Input, validation, approval workflow and archiving
Data exchange between your applications, ERP, CRM, GIS
Secure access, document management, project tracking
Custom web applications
A website displays. An application does. We develop web applications with data input and output features, advanced user interfaces and custom backend components, designed to integrate into your information system and communicate with your existing tools.
- UX/UI design focused on business efficiency
- Frontend development: React, Angular, advanced HTML/CSS
- Custom backend: Node.js, PHP, Java, Kotlin, .NET
- REST APIs and inter-application exchange components
- Connection to your existing databases (PostgreSQL, MySQL, SQL Server…)
- Authentication, rights management and application security
A fast and proven method
We have developed a framing method that reduces back-and-forth and accelerates time to production. Every project starts with a definition session that aligns style, design, content and objectives before the first line of code.
Framing
Objectives, targets, content, design and architecture defined together in 1 to 2 sessions. No surprises along the way.
Design & Prototype
Functional mockup validated before development. What you see is what you get.
Development
Short sprints, intermediate deliverables, continuous feedback. Certified Scrum method.
Deployment & Security
Hosting, server configuration, HTTPS, data protection. Managed by our infra team.
Accelerated by AI, validated by humans
Our developers co-create with AI tools (Claude, Mistral, Gemini) to accelerate development without sacrificing quality. AI generates, our experts validate, test and integrate. The result: faster delivery and more solid code.
Mastered technologies
From development to secure deployment
Development does not stop at the code. We manage the entire lifecycle: Swiss hosting (Infomaniak), environment configuration, application security and access management, with the infrastructure expertise of the IT IS GIS group.
- Preferred Swiss hosting (Infomaniak, LPD compliance)
- HTTPS configuration, SSL certificates, security headers
- Application protection: authentication, session management, input validation
- Separate development, staging and production environments
- Availability monitoring and alerts
The hosting and security of your web projects rely on the infrastructure expertise of the IT IS GIS group: the same skills that secure organisations of 1000+ users.
