Who we are 

We are a Ukrainian multiproduct company that creates database development and management tools, connectivity solutions, productivity tools, and data services for more than 500.000 clients from 120 countries. Among our clients, you can find such legends as Microsoft Corporation, Oracle America, IBM, Intel, and many more companies that deserve their place in the Fortune 100 and Fortune 500.

Since 1997, we have been streamlining data workflows for professionals and teams with our intuitive and efficient software products. We’re committed to enhancing our customers’ experience across the globe by minimizing data-related tasks and enabling them to focus on more inspiring goals.

• Experience designing and building REST APIs.
• Strong experience with relational databases such as SQL Server or PostgreSQL and ORM tools such as Entity Framework Core.
• Understanding of authentication and secure application development, including OAuth 2.0 and JWT.
• Experience with automated testing using frameworks such as xUnit or NUnit and mocking tools such as Moq.
• Experience with Git-based development workflows, including pull requests and code reviews.
• Practical knowledge of Docker / Docker Compose and basic CI/CD practices.
