Delivered value

Lemberg continuously provides Chris with dedicated teams. At first, a team of our mobile engineers helped the client build a mobile app for iOS and Android. And now, our DevOps and back-end engineers maintain and support their servers, repositories, and databases under an SLA.

The process

We engaged with the client when they were looking for senior mobile engineers to finish their mobile development on time. Instead of relying on freelancers or wasting time hiring in-house, they came to Lemberg for a dedicated development team. 

Within less than a week, our team was on-site at the client’s office. Onboarding was crucial because our engineers needed to figure out the existing codebase and workflow before they could get started. Once they were up to speed, our dedicated team helped the client deliver an iOS and Android app for Chris. 

The next — and current — step in our collaboration is to help the client with back-end development and DevOps services under maintenance and support agreement (SLA). Our dedicated team handles Chris’s servers, repositories, and database; maintains and improves their back-end and API. 

Our work helps the client build a better product and continuously improve the experience of their users.

Lemberg engineers were very skilled and very much engaged to our project. They gave their best for the project and didn’t hesitate to do overtime in order to meet the deadlines. There was also a great cultural fit. They developed very good relations with my team.
