We know how to address your technology shortcomings

Our solution

1. The application is slow and crashes frequently

Our experts will improve your app architecture & infrastructure, add caching and optimization techniques, and keep monitoring & fixing performance bottlenecks continually.

2. The system has grown in size and complexity,
and can't be scaled easily

By implementing microservices and containerization, we can make your app more scalable so that you can easily add new features and maintain them in the future.

3. The solution requires external data to be integrated
smoothly and efficiently

We will pull data from third-party APIs to facilitate data exchange between systems and use containerization technologies to ensure seamless integration of external data.

4. Outdated technology no longer supports your
business needs

With a technology upgrade or migration to more modern, flexible, & scalable systems, we can help you better align your software with the current and future needs of your business.

What our clients say

Read what our clients think about cooperating with JatApp.

The “handshake” between microservice and existing software was very efficient

“After launching the microservice we were way more flexible in enhancing our SaaS solution with new features. The “handshake” between microservice and already existing software was very efficient.”

Erik Boska
CEO, Real Estate Platform

The development team was so experienced

“We are currently testing our beta version. We aren’t ready to sell it yet, but our tester clients show that it is working well. We can see every detail through strong business analysis and we were happy to find a development team that was so experienced.”
