We design web, admin panel and mobile interfaces that help users find what they are looking for and complete their tasks.

Which interfaces do we design?
Data-dense screens
On planning, quality control and reporting screens, we arrange information in order of importance. Users can see alerts and task statuses as they drill into the details.

Shop-floor and tablet interfaces
We design shop-floor screens with large buttons and clear field labels. We arrange how data such as production counts, work orders and downtime reasons is entered to suit the working environment.

Map and operations panels
We design screens for tracking shipments through maps and lists, showing delays and status changes in the relevant record.

Client portals
We design portal screens where clients can track their own shipments, documents and delivery status.

Mobile app screens
We design screens that let field staff follow tasks, deliveries and required documents from their phones.

We design every screen with shared rules.
Design system
We define shared rules for recurring elements such as buttons, forms and tables, so new screens can use the same components.
- Button
- Form
- Table
- Notification
- Status label
- Dialog
- Empty state
Empty, loading and error states
We also design what users see when there is no data, loading is in progress or an action cannot be completed.
- Empty list
- Data loading
- Action failed
- Unauthorised access
Accessibility
Contrast, keyboard use and form labels are part of the design decisions.
- Contrast
- Keyboard
- Form label
Consistent status indicators
We use consistent colours, labels and icons for each status across screens, so users do not have to rely on colour alone.
- In transit
- Planned
- Delivered
- Delayed

More about this service
UX design addresses the steps a user takes to complete a task. UI design defines the screen layout, controls and visual design for those steps. At Şahan Design, we develop the flow and interface together.
The user's task
We first examine who performs each task, what information they need and where they struggle. For an existing product, we review screens, feedback and available usage data. We plan the work needed for user interviews and testing separately.
Flows and wireframes
We map task steps, information order and transitions between screens. We use simple wireframes to decide where content goes. At this stage, we also handle states such as empty lists, loading, errors and unauthorised access.
Interfaces and shared components
We create shared rules for colour, typography, spacing, buttons, forms and tables. We check components at different screen sizes with realistic sample content. Readability, keyboard use and form labels are part of the design.
Prototype and handover
A clickable prototype lets us review key tasks before development begins. We deliver screens, components, assets and behaviour notes in a file developers can use. If software development is also needed, we agree its scope separately.
See our Meridyen and Arven dealer portal projects. We can also discuss our admin panel and mobile app development services.
Our Projects
How does the process work?
- 01
Tell us what you need
You tell us what you want to do, and together we pin down the scope.
- 02
Approve the quote
Once the scope, stages and price are clear, you approve the contract and payment plan in the panel.
- 03
Follow the process
We share the work at the agreed stages and review your feedback together.
- 04
Take delivery
For handover, we prepare the files and usage information covered by the approved scope.

You can pin down your project's scope and working steps with our design and development team.
Reviews
We’d like to thank Abdullah for his attentiveness and professional approach. We had our own ideas in mind for our corporate logo. With Abdullah’s creative work, it evolved into something completely different. As a company, we were very pleased. I’ll definitely be calling him for future projects.
Thank you for your care and attention right to the end. Our cover was designed meticulously. 👏
Great work 👏👏
I was very pleased
The way Abdullah ran the process, answering all our requests with patience and understanding, was admirable. We worked together and got there. Thank you.
Amazing logo designer
Thank you, Şahan Design. It turned out to be a really nice piece of work, and I liked it a lot. Very high-quality touches.
Frequently asked questions
What is the difference between UI and UX design?
UX defines the steps users take to complete a task. UI designs how those steps appear on screen. We work on both together because flow and presentation influence each other.
Can you redesign an existing application's interface?
Yes. We first review the existing business rules and technical constraints. Updating the appearance and changing task flows involve different work. We agree what to keep and what to change at the start.
Is a clickable prototype a working application?
A prototype demonstrates screens and transitions. Real data storage, permissions and integrations are implemented during development. The prototype lets us review key tasks before coding begins.
Does every project need a design system?
Its scope depends on the product's size. Basic colour, typography and component rules may be enough for a small project. As the number of screens grows, we organise those rules in a more detailed component library.
Do you carry out usability testing?
We set the scope of user testing separately, and plan the participants, tasks and evaluation method together. Reviewing the prototype with your team is part of the design process.
Is development included in UI and UX design?
This service covers the design work. We prepare the screens and behaviour notes ready for handover to developers. If you'd like us to build the software as well, we can plan that separately within the same project.
Let’s bring your project to life together.
Brand identity, packaging, web or custom software. Tell us what you need and we will define the scope, process and budget together.
