Custom applications

We are constructing custom tailored software solutions from the very well crafted back-end in either Java/Grails or PHP/Perl, to very practical front-end. We are making web, desktop and mobile applications from scratch, assisting you from the day one of project. We are helping you review, maintain and reorganize existing solutions. Our services go far beyond the code development. We provide deployment, maintenance and user experience design services. Our applications are developed with care. We know the "little-big details" are making the difference and decide if application is just working fine or have a great, positive impact on your business. We are looking for challenges, building large and small, scalable enterprise solutions based on well evaluated cutting edge technologies.
