UI/UX design agency.

Interface design from user flow to developer delivery for mobile, SaaS and e-commerce products.

UI/UX design agency

We are an Istanbul-based UI/UX and interface design agency. We work remotely with teams in Türkiye and abroad. This service covers design; software development is scoped separately.

We work on mobile application, SaaS panel and e-commerce streams. We do not draw screens without user flow and information architecture becoming clear; we install the design in Figma and deliver it in a way that the developer can use directly.

This service covers the design side; coding remains on your team.

When looking for a UI/UX design agency, you can evaluate user experience coverage together with interface design. In Figma interface design, we also clarify interaction states alongside screens and the rules to be passed on to the developer.

Scope and deliverables

User research, user flows, interface screens and interactive prototype are different outputs. The current state of the product and the tasks to be tested are initially determined. The Figma file is not a standalone application delivery.

Pricing and proposal scope

The UI/UX design offer is determined by the number of screens as well as roles, empty and error states, components, and the need for research. Behavioral notes, situations, and the agreed upon design system are explained in the delivery to the developer.

FROM IDEA TO DELIVERY
01

Define the scope.

Together, we clarify the goals, audience and scope of the project.

02

Develop the design.

We explore the visual direction through concrete examples, then refine it with your feedback.

03

Prepare for handover.

We hand over the agreed files and usage details in an organised format.

Where UI/UX design ends and development begins

This service covers interface and experience design. Software development, databases, hosting and app store release require separate scope. Research and usability testing, when needed, should specify a method, participants and deliverables in the proposal.

Brief and handover checks

We start with product goals, user roles, priority journeys, existing screens and technical constraints. Handover checks cover agreed screens, interaction states, components and developer notes. Changes to screens or features require a review of scope and timing.

See the Libera mobile interface, RBS website design and Hospitra website design. Kortex’s role in these projects was design agency; these examples do not claim software delivery or measured commercial results.

Startup and MVP product design

How do we narrow down the scope of the first product?

The starting point in MVP design is not to draw all the features, but to determine the flow in which the user will complete his basic work. User flow, low detailed screens, interactive prototype and interface design can be planned as separate submissions. The prototype is clarified during the bidding phase where there is no running software.

What is required for the UI/UX design proposal?

What problem the product solves, the target user, the current research and technical constraints are shared. Price depends on the complexity of the flows, research, testing, design system, and delivery to the developer, alongside the number of screens. Examine the design working model for initiatives.
