Do you take on large, long-running projects?

Yes, that's our specialty: we run projects lasting from a few months to several years, with custom integrations and complex logic.

Can the service be connected to our systems?

Yes. We integrate with accounting systems, CRM, payment and other services, and open an API for mobile apps and partners.

Do you have similar projects?

Yes: the Oneunion social network, the Maxmeet events platform, the Skillexpress education platform, the Union Wallet settlement system and others — see the portfolio.

How much does development cost and how long does it take?

It depends on the scope. After discussion and the specification we give a transparent estimate and fix cost and timeline in the contract.
