Openkoda: Core Travel Insurance live in eight weeks, SkyGuard on the same platform
Stratoflow as implementation partner for the Openkoda insurance platform: a travel insurer from contract to production in eight weeks, and a life and aviation specialty insurer.
8 weeks to production
We are very pleased with our partnership with Stratoflow and, as we continue to grow, we expect to increase the numbers of developers that work with us on our projects. They have proven to be very skilled and flexible. They're extremely reliable, and they have a very good company culture of their own, which gives them a real edge compared to other providers that serve more as production shops rather than thought partners and creative problem solvers.
Before you choose an industry page
Do you only work in these industries?
No. These are the industries our case studies come from. The engineering carries over wherever a high-volume Java system runs the business, and the scoping call is where we tell you whether we are a fit.
Which industries do you know best?
Banking, fintech and insurance, where most of our work and our deepest references are: the FastPost ledger and our Openkoda implementations. Travel and ecommerce follow, through the hotel metasearch engine and Recostream.
How large is the team?
A boutique team of senior engineers in Poland, all direct employees, with no subcontracting.
