Application modernization

Why do we offer app modernization services?

While green-field projects can be interesting for most developers, the most challenging will always be the ones where you deal with tech debt. Improvement of existing applications or legacy systems is always tricky, extremely difficult and unique. This is definitely not a task for a junior developer, but rather a much-needed test of skills for the senior developer. It demands great expertise and patience from the technical standpoint, but also a deep understanding of business processes in order to make such an ordeal profitable. That gives us the best opportunity to hone our skills even more, while also granting the best solution on the market for our client.

Quotes
What I like most about app modernization is that both business people and developers can immediately see the benefits of it. Improving a system that is making money allows one to reap the harvest from the first day. Each change makes development easier, infrastructure cheaper, and users happier. It drives conversion and it brings happiness to the development team.

Ensure your application can keep up the pace when you scale up for new users

There are many obstacles along the way when scaling a web application. Often, popular apps are not able to handle their own success. Quite often, adding new features has to be done quickly, especially during the early years. As a result, the code becomes hard to maintain and blocks innovation. It is often less secure, the technologies used are outdated, development becomes slow, app performance drops.

Application modernization services that we offer can help with all of that. In fact, we helped already a dozen of legacy applications. Our experienced developers carried out multiple architecture audits, prepared modernization strategies, plans for infrastructure migrations, moved from monolith to microservice and refactored codebases.

What is important, we always plan for full operational excellence during the whole modernization process. No downtime and no feature freeze.
