we do

Our brightest minds use the latest technologies along with agile development methodologies in order to implement your ideas into an intelligent product. We work directly with you, providing personalized unique solutions that cater to your area of business. Enjoy the development process with us and make complex processes easy.


In order to create a great app we investigate your project and make sure that we are on the same page as you. Then we move forward with the design applying years of our experience to produce a refined app concept.


Without creating a prototype it’s hard to capture the app flow. As a rule we employ wireframes to break the app into screens and transitions. After the overall app flow is approved by the customer, we apply our graphical designer skills and creativity to produce catchy pixel-perfect design.


We employ Agile approach to produce high quality deliverables in a timely manner. The process is structured in the way that the course of development can always be changed if required by the customer.


We remain in close touch with our customers after the release. Successful apps require continuous support and extension based on gathered statistical data and user reviews. We help analyze the available metrics and make right conclusions.

Founder, Barbershop

I've been working with YELK since I started up my Barbershop. YELK team has helped me to choose appropriate solutions for my business. They have optimized all of the processes at the salon and as a result, it has become very popular and now attracts a lot of new clients. I'm going to continue our cooperation with YELK and certainly recommend them. YELK is a team of highly qualified professionals who know their job perfectly.

CEO of restaurant chain

I used a ready developed ordering system for a long time, but it was unreliable and expensive to maintain. So I decided to develop my own one with YELK. They built ordering system from scratch. It complies with all my requirements and satisfies all my needs. During our cooperation I got a stable and well optimized product meeting deadlines. YELK team helped me to save money and quickly achieve positive results.
