About Service
UI Engineering connects product thinking, interface design, and frontend code
UI engineering is the process of designing and implementing the interface layer of a digital product as one connected system. Instead of separating UX, visual design, components, and development delivery across multiple vendors, our team works through the full interface lifecycle — from flows and prototypes to reusable coded components, QA, and launch support.

FAQ
Answered questions
1
What is UI engineering, and do I need it?
UI engineering combines UI/UX design and development within one coordinated process. Instead of receiving design files and then searching for a separate development team, you can take your product from idea to launch with Cosmos Studio. This service is a good fit if you want to launch faster, avoid managing several agencies or contractors, reduce gaps between design and development, and have one team responsible for the final result.
2
Can I come to you with just an idea?
Absolutely. You do not need to have a detailed brief, designs, or technical documentation. We can help you shape the idea, define the product scope and functionality, create the brand and interface, and take the project through development, testing, and launch.
3
Do you provide backend development too?
Our in-house team handles UX, UI and frontend development. Backend, mobile and DevOps are delivered with trusted engineering partners. You still work through one coordinated process, with Cosmos Studio managing the project, communication, design alignment and quality.
4
How long does a project take?
Most projects take around 4–8 weeks. The exact timeline depends on the scope, complexity, required integrations, and the current stage of your product. Contact our client manager to discuss your project and receive a more accurate timeline and scope estimate.
5
How much do UI/UX design and development cost?
The cost depends on the size, complexity, functionality, and technical requirements of your project. To provide an accurate price, we first prepare a detailed project estimate. The estimate is free and does not commit you to starting the project. Contact our client manager to discuss your requirements and receive a tailored calculation.
