Review Summary

We choose Kolosek to assist us with creating our App for Human Resource Social Network and a few other things.
Upon conducting an extensive search for possible development partners throughout multiple countries, we selected Kolosek to provide us with:
- Platform strategy
- Architecture
- Development specifications
- Systems setup
- UI/UX Design
- Front & Back-end Development
- Testing
Through out the project we have been extremely satisfied and Kolosek have surpassed our expectations many times and on many areas.
Especially their flexibility, their ability to value add, their engagement in our project as if it was their own baby, their many suggestions for improvements and enhancements, and their rock steady hand and management of the project even in the hard times you always experience at times when the code is challenging you or limitations impose themselves on your scope and requirements. They have been amazing and their CEO is a constant source of comfort and trust.
I have worked with external development houses in India, Poland, Scandinavia, US, Pakistan, Ukraine, Germany and a few other places, and I would choose Kolosek over again anytime.
Our product which is in a soft launch phase with test clients, have become the great App it is, not least because of all the wonderful people at Kolosek. It's been an inspiring and learning process.

Review Summary

After a couple of years of trying to find a good fit for our development needs and dealing with people that just didn't understand what deadlines are we finally found our home with Kolosek and won't be looking back. After two years of working together with these guys I can say that it'll be hard to top the level of service that they deliver.
