A team you can count on

We are battle hardened developers and designers and we will bring your idea to life.

Hire us
Custom solutions

Your idea is unique. The implementation could be nothing less. We build applications from scratch using the most suitable technologies. We don't count on existing libraries. If something doesn't exist, we will create it.


Do you have an idea? We will create a minimum viable product for you to test. We know how startups are built. A development team is not a priority for you now and we are here to get you rolling.

Deliver on time

What makes sense now, won't always make sense. We understand how important deadlines are and we will do our best to never overpromise. We prefer to deliver sooner rather than later.

Pavlos Kallis
Full stack, Single page apps

Pavlos is one of those guys who like Javascript. He is fluent in Ruby and SQL too but still his latest favorite is ReactJS. He keeps an eye on the goal and alerts the team when focus is lost.
