Web application design · frontend & backend: Web applications designed end to end
We design every kind of web application, from the interface people use to the backend that runs it: clear, accessible and secure by design.
Good design goes all the way down
A beautiful interface on top of a fragile backend is not good design. We design the whole application: user experience, interface and frontend, together with APIs, data models and backend services. That gives you web applications that are easy to use, fast to develop further and secure from the ground up. When services are easy to understand, people also make fewer mistakes, so good design is good security.
Every kind of web app
Portals, SaaS, e-commerce, booking, internal tools and patient systems.
Frontend, UX & UI
User research, interface design and components that are fast and consistent.
Backend & API design
APIs, data models and services designed for security, performance and change.
Sensitive & patient data
Design for privacy, access control and traceability, built on 15 years of patient systems.
Accessibility
WCAG 2.2 AA compliant design that works for everyone.
Design systems
Reusable components that speed up delivery and keep everything consistent.
Web design for every kind of web application
Customer portals, SaaS products, e-commerce, booking systems, internal tools and patient systems all have different users and different demands. We design for each of them, with the same focus on clarity, speed and security.
- Customer and member portals
- SaaS products and dashboards
- E-commerce and booking
- Internal tools and admin interfaces
- Patient and healthcare systems

Frontend and backend, designed together
Design decisions in the interface affect the API, and decisions in the database affect what users can see. We design all layers together, with a security control in each: safe input in the frontend, authentication and validation in the API, least privilege in services and encryption in the data layer.
- UX, UI and component design
- API design: REST or GraphQL, contracts and versioning
- Data models built for privacy and retention
- Security designed into every layer
- Performance and scalability from the start
Designing for patient data
Few kinds of data are as sensitive as patient data. With 15 years of designing and running a patient system for private healthcare, we know how to make systems that are easy for clinicians to use while protecting every patient: role-based views, masked identity numbers, consent and a full access log.
- Role-based access, so each user sees only what they need
- Masking of personal identity numbers and sensitive fields
- Consent handling and traceable access logs
- Designed for daily clinical work, not just for compliance
- GDPR and healthcare requirements built in

From idea to validated prototype
We move quickly from concept to clickable prototypes and validate with real users before a single line of production code is written.
- Concept and service design
- Interactive prototypes
- Usability testing
- Hand-off to development
Accessible and responsive by default
Your users are on phones, tablets and large screens, and some rely on keyboards or screen readers. We design so the application works for all of them, and meets WCAG 2.2 AA.
- Responsive design for every screen size
- WCAG 2.2 AA: contrast, keyboard, screen readers
- Fast loading and clear structure
- Accessibility testing before launch

Case · Healthcare
A patient system for private healthcare, in production for 15 years
armsec's founder designed and developed a patient system for private healthcare providers, with applications connected to SLL (Region Stockholm). Clinics have used it in their daily work for 15 years, and they still do today. Building software that handles patient data for that long requires security, privacy and reliability to be part of the design, not added afterwards.
